Subject: Seal AQ2 Discrete Analyzer Technical Report
PURPOSE: The purpose of this report is to introduce a complete examination regarding the laboratory’s need for automation equipment in order to keep up with the influx of the Total Kjeldahl Nitrogen (TKN) samples that have overwhelmed or staff since the new guidelines from the Environmental Protection Agency.
SUMMARY: Environmental Laboratories have been finding that by adding automated instruments increases productivity as well as leads to significant business growth. Laboratory owners and managers are seeing the benefit to automating some of the tests that they run. Having a machine like the SEAL SQ2 Discrete Analyzer that can run multiple methods, eliminate human error, save valuable employee time, and use less space will be a much needed addition to our laboratory. The software that is integrated into the analyzer will flow seamlessly into the laboratory information management system (LIMS) we already have in place.
DESCRIPTION: The AQ2 discrete analyzer from SEAL Analytical is an extremely automated flexible analyzer that analyzes samples and gives exceptionally accurate data. Automating the Total Kjeldahl Nitrogen method is needed in order to keep up with the influx of new customers needing to comply with the new EPA regulations. The AQ2 analyzer is the same size as a tabletop microwave and is connected to a computer that will allow the analysts to analyze the data collected at a fast pace. The analysts needs this effective tool in order to be able to save time and ultimately money. Machines in the laboratory are nothing new, this analyzer takes what was a full 12 foot lab bench and places it on the bench in a 12X15 inch area.

Analyzer: The front of the analyzer had a clear screen that can be lifted in order to place samples into the tray or remove them. The analyzer uses a robotic sampling arm that draws a preloaded sample in through the syringe and deposits it into a reaction well along with the correct amount of reagent. The reagent and sample are allowed to react for a precise amount of time and then an aliquot is transferred to the stop/flow Optical Quality Glass Cuvette. The absorbance is then read and the cuvette is cleaned and made ready for the next sample. Software: The software has been designed for ease of the analyst, it is very similar in look and style of LIMS. There are two version of the software, depending on the methods that are chosen. You can choose to have only one method installed or choose to have thirteen of them in order to run all of the supported tests.
Application: This will take the place of testing for TKN by distillation. Analysts will be able to run more samples in a fraction of the time. If in the future the laboratory decides to automate other tests the AQ2 has the ability to do that. Methods supported by the SEAL AQ2 are: Alkalinity, Ammonia, Chloride, Cyanides, Nitrate/ Nitrite, Nitrite, Phenolic, Phosphate, Ortho, Phosphorous, Total Silicate, Sulfates well as Total Kjeldahl Nitrogen.
COMPARISON WITH OTHER TECHNIQUES, OR PRODUCTS: * TKN by distillation has been used for years and is the standard method. One run of 4 samples at this point is taking 1 hour. Distillation is a quite lengthy process: first the analyst takes a measured amount of the sample and mixed it with two separate reagents, then the receiving flask must be prepared, after all of this occurs distilling takes an additional 40 minutes. In 8 hours 32 samples can be run, this is not takin the QC run into consideration.

ADVANTAGES OF SEAL AQ2 DISCRETE ANALYZER: Laboratory managers have been seeing the benefits of having automated equipment in their laboratories for decades. The SEAL AQ2 discrete analyzer will significantly reduce time spent analyzing samples, keep data errors and operating expenses down, and improve laboratory safety. * Increase Productivity: Automation can significantly cut down on the time it takes to run a sample. Prep time is cut down by 75% which in turn will make turnaround faster. Analysists are able to start preparing the next run as the machine is running the current samples. * Improved Data Quality: Data is taken from the analyzer and entered spontaneously to its software and is entered automatically into LIMS database. This saves time for the analysts by not having to enter it manually and keeps paperwork errors down. * Reduced Operating Cost: A fragment of the amount of reagents are needed in order to evaluate the samples this lowers costs. * Improved Safety: Employees are not handling reagents as often as they are added into the tray in the beginning of the run.

DISADVANTAGES OF SEAL AQ2 DISCRETE ANALYZER: While

* Upfront Cost: The upfront cost is between $30,00.00 and $35,00.00 depending on the software purchased with the analyzer. * Standards Development: New standard methods will need to be created and put into place. The rough estimate is between 3 -6 months. * Training Time: The purchase price includes a week of training for 2 employees. As with anything new it will take time to get comfortable with the analyzer and the software. CONCLUSION: Benefits for the Laboratory include being able to save time, money, boost productivity, and waste. I believe that the benefits justify the cost. Looking at the research spreadsheets the laboratory will increase production by 143%. The addition of the SEAL AQ2 discrete analyzer would be a significant asset to ourselves as well as our clients. Faster turnaround time leads to a more profitable business.

3d Printing

...How exactly does a 3D printer work? Before the 3D printer was developed, the 2D printer was still a fascinating machine to many people. With a 2D printer, what was printed out on a piece of paper was put together and designed on a computer program such as Microsoft Word or Presentations. The file that the printed image or information was created in holds the instructions that the printer is to follow. A 3D printer also needs a file and instructions to print. The goods or designs that are printed can be customized, because altering them will not require complete retooling, only slightly adjusting the instructions in the software. The file is known as a Computer Aided Design (CAD) or Computer-Aided Manufacturing (CAM) file that requires the use of a 3D modeling program, or with a 3D model using a 3D scanner. This software quickly slices the model or design on the program into hundreds or thousands of thin-sliced, horizontal layers. The layers get printed one by one atop of one another until the 3D object is complete. Owners of 3D printers can choose between 2 types of plastic strands: acrylonitrile butadiene styrene (ABS) or polylactic acid (PLA). Some 3D printers can use both kinds of plastic, while others only work with one. These plastics are available on spools with plastic strands/strings that are usually 1.75 millimeters thick or 3 millimeters thick. Gears work to pull the filament through the print head. Immediately before it is pushed through the pointed nozzle, the...

...ABSTRACT 3D printing is a form of additive manufacturing technology where a three dimensional object is created by laying down successive layers of material. It is also known as rapid prototyping, is a mechanized method whereby 3D objects are quickly made on a reasonably sized machine connected to a computer containing blueprints for the object. The 3D printing concept of custom manufacturing is exciting to nearly everyone. This revolutionary method for creating 3D models with the use of inkjet technology saves time and cost by eliminating the need to design; print and glue together separate model parts. Now, you can create a complete model in a single process using 3D printing. The basic principles include materials cartridges, flexibility of output, and translation of code into a visible pattern. 3D Printers are machines that produce physical 3D models from digital data by printing layer by layer. It can make physical models of objects either designed with a CAD program or scanned with a 3D Scanner. It is used in a variety of industries including jewellery, footwear, industrial design, architecture, engineering and construction, automotive, aerospace, dental and medical industries, education and consumer products.

...Robert A. Bratton ITT-Tech Printing the future in the not too distant future people should have access to 3d printing machines giving them the ability to make virtually anything that they can think of. Just over the past few years the technology has jumped by leaps and bounds. We have gone from 2d printing on paper to laser printing in gel and no we have printers that can scan and reproduce at least the exterior of an object. [Title Here, up to 12 Words, on One to Two Lines] The biggest advantage of having the ability to 3D print an object is it allows you to skip a large amount of the design faze and move more into production faster. By having the model printed early in designing a product it allows the designer to see flaws in the design allowing for faster correction. Another advantage is to the private sector it allows individuals to print things that they can use without having to run around and shop for thing that they might need like spoons, forks, bowls, and cups. The cost of 3D printers has decreased dramatically since about 2010, with machines that used to cost $20,000 now costing less than $1,000. For instance, as of 2013, several companies and individuals are selling parts to build various designs, with prices starting at about $500. The open source project has developed printers for general use with anything that can be squirted through a nozzle, from chocolate to silicone sealant and chemical reactants. Printers following the project's designs have been...

...of researchers at UNC-Chapel Hill have developed a new 3D printing process that will significantly reduce the amount of time it takes to complete a project as well as increase the smoothness and quality of the product produced (Moren, 2015). This new process is called CLIP, continuous liquid interface production, and they claim it can print smooth, complex objects in a fraction of the time as existing systems, and using a wider variety of materials (Moren, 2015). This product has the potential to completely change 3D printing. This new process allows the object to be built up from a pool of liquid resin, curing the resin as it rises. CLIP's creators say objects can be produced 25 to 100 times faster than old-school methods (Moren, 2015). In addition to it being much faster, it uses a variety of other materials, and can produce much finer parts, which allows the builder to make a much higher quality product. If the quick process and better product weren't enough for the consumer to love, watching the product rise from a pool of liquid resin will be the selling point. It is a fascinating process. This product has yet to release cost information, however 3D printers have been used for many different purposes. They are often used to create models for architects or inventors. It has been used by the military, engineers, for dental purposes, and even in the medical field. Last year a group of surgeons used a 3D printer to make a replica of a child's heart in order......

...In my 3D printing is a vastly expanding field with the excitement and use for 3D printing growing every day. In this paper I will talk about the beginning history of 3D printing and touch on the multiple areas of the economy it will slowly change such as manufacturing, architecture, cooking, prosthetics, organs, and more. The beautiful thing about 3D printing is the possibility of thinking “I can build and make anything I can think up on my own” is amazing. With the length of time it takes to come up with an idea to creating that idea to it being outsourced for manufacturing 3D printers decrease time and money by essentially cutting out the middle man making it so much easier for the consumer. If you are someone in need of a prosthetic extremity 3D printing can decrease the price and time on receiving that prosthetic. For these reasons I extremely believe that 3D printing will drastically change things economically around the world. In history of 3D printing since 1984 there has been extreme progress each year. The 3D printer evolved from the ink jet printer with the idea to substitute ink with actual materials in successive layers to create a physical object from a digital file. Charles Hull the co-founder of 3D systems invented the stereo lithography apparatus (SLA) a printing process that allows a 3D object to be created from digital data.

...3D Printing: New Technology Solving World Problems Berenthia Smith Lecturer: Dr. Raymond Wells Due Date: 23rd January, 2016 College of the Bahamas Abstract In the 21st century, it is inherent to say that technology is new. The word technology is symbolic of the word new in and of itself. Technology is created every day. The human race continues to grapple with the issues of today’s world and how technology can be used to solve world problems. The concept of 3D printing is discussed in relation to cost, customization and diversity. It is visible how 3D printing plays a role in solving world problems. According to White and Bruton’s definition of technology, it is defined as the way people use learning and knowledge to assist progress (2011). In other words, when people and businesses find new ways to use their experiences to solve problems, it is known as technology. Today, there are a number of technologies that are popular; whether it be because they are trendy or because they are rather useful. One of these technologies is Three Dimensional Printing (3D printing). Hoffman’s article defines it as the use of a machine to print objects through a layering process. The machine is controlled by data files usually generated from Computer Aided Drafting (CAD) or Computer Aided Manufacturing (CAM) software. The differences between 3D printing and traditional production is that the objects created the traditional way, once completed, will sometimes have to be further......
