Food SAFETY is a primary concern for manufacturers and consumers World-wide. While there is always concern for the Food PRODUCT itself… from either Microbial or Chemical contamination… there is also a need to preserve Food for storage and ...
In today’s world, over 75% of all metal surfaces on manufactured metal “items” have some sort of plated finish on them. From highchromium steel car bumpers to zinc diecast toys to Silver-contact electronic components. While the primary composition ...
The Earth is 75% water, as are most life forms on Earth. People need to drink several quarts of water a day to live well, and most of us prefer to consume beverages other than water to satisfy our thirst. Soda (or Pop depending on your location) is ...
The government and the military have spent millions of dollars on making millions of tons of explosive materials. Most of these materials are warehoused in storage depots and often-present problems with leaking containers and contamination of the ...
Infrared Spectroscopy (IR) is one of the most descriptive “tools” available to the analytical organic chemist both for qualitative identification and quantitative determination of single and mixed components. Classically, most samples have been ...
There are STANDARD Guidelines used to define the Identification and Purity of compounds used in Pharmaceutical and Cosmetic formulations, as well as the final Products. These protocols are described in great detail in the various Monographs of the ...
While the growth of technology and industry has given us a high standard of living, it has also given us a greater amount of waste products to deal with. A significant portion of the waste is either buried underground or stored in abandoned ...
Semiconductor components are made primarily from surface-doped substrates of silicon, gallium arsenide, mercury-cadmium telluride, and other highly refractive metalloid materials. Special lenses and mirrors usually have a specific coating to impart ...
Normal quality control procedures involve accepting a “lot” of a raw material from a supplier and then performing a series of tests to determine if the material is suitable for use in a manufacturing process. For the drug manufacturing ...
Processing waste discharges, manufacturing effluents and sewage would not normally have been a problem 50 years ago, but the advent of almost unchecked industrial growth the latter half of the last century has created the POTENTIAL for a wide ...
The distillation of Naphthenes and Coal Tars results in a complex array polynuclear aromatics, or which many do not show up in an analysis by GC-TCD or FID because they are at trace levels in the sample. In some cases these trace products are ...
The analytical chemistry of PCB’s is rigorous, demanding the highest quality in sample preparation and analytical technique. Insufficient sample extraction and inappropriate methods of sample clean-up are the most common sources of error in PCB ...
Although leaking underground storage tanks account for the majority of gasoline contamination in soils and groundwater, other events such as accidents during product transportation or delivery are also significant. Spill clean-ups and tank ...
The EPA regional offices who continuously monitor ambient air quality have determined that combustion by-products and automobile exhaust make up the largest source of air pollution throughout the U.S., with more severe conditions existing ...
To help build a comprehensive Industrial Hygiene program, Buck Scientific introduces the IH910 vapor monitoring system utilizing our model 910 gas chromatograph and IH300 air sampling train. Designed to analyze hydrocarbons in air, such as ...
Since 1963, when Rachel Carson published Silent Spring about the destructive power of synthetic chemicals, regulatory agencies in the U.S. have increasingly restricted the manufacture and use of pesticides. The goals of pesticide regulations ...
Because of the widespread use and history of indiscriminate disposal practices of gasoline and fuel oils, their analysis in environmental samples is in high demand. Gasoline and diesel are both complex mixtures containing up to 400 individual ...
The complex mixture of condensible hydrocarbons and permanent gases in a natural gas product has historically been separated on gas chromatographs equipped with dual columns and a switching valve. The light gases are separated from heavier ...
