    Analysis of Herbicides in Drinking Water

    Herbicides are used throughout the world to combat the growth of unwanted plant life. These polar compounds are hydrophilic, so they may find their way into drinking water sources. While gas chromatography has historically been the preferred technique for analysis of herbicides in water samples, the use of LC-MS/MS for this application is gaining acceptance. This is due to the power of MS/MS to provide detailed identification of multiple analytes, but also in part due to the variety of HPLC stationary phases...

    Measurement of ethylene oxide for monitoring workplace exposure limits

    The Series 8900 Ethylene Oxide Analyzer combines the selectivity of gas chromatography with the sensitivity of a Photoionization Detector (PID) providing interference free response to Ethylene Oxide (EtO) at levels below 0.05 ppm. This analytical method is referenced in OSHA`s `Occupational Exposure to Ethylene Oxide: Final Standard` 29 CFR Part 1910. The system documents exposure levels including: time-weighted averages (TWA), short-term exposure limits (STEL) and instantaneous alarms. Areas that are typically...

    DETERMINATION OF TOTAL PETROLEUM HYDROCARBONS (TPH) IN WATER BY FLUORIMETRIC METHOD

    Total petroleum hydrocarbons (TPH) is a term used to describe a large family of several hundred chemical compounds that originally come from crude oil; the main and most specific part of these compounds are non-polar and slightly polar hydrocarbons of the aliphatic, aromatic and alicyclic structure. These compounds are harmful to humans and animals if absorbed through the skin, ingested, and inhaled thus claiming the analytical control of THP content in water as a global issue. Quantification of TPH in water is...
