Analysis of Trichloroanisole in Wine and Cork using a Purge and Trap Multimatrix Autosampler
Abstract Due to its low odor threshold, 2,4,6-trichloroanisole (TCA), the compound responsible for “cork taint”, requires extremely sensitive analysis. TCA is a fungal metabolite of 2,4,6-trichlorophenol (TCP). Even minute contamination can cause issues with regards to taste. This study will demonstrate a purge and trap method for analyzing wine and cork samples at the ...

Analysis of Volatile Organic Compounds in Different Beverages
Abstract Volatile Organic Compounds (VOCs) have been a major concern of the U.S. Environmental Protection Agency (USEPA) leading strict regulations of VOCs present in drinking water. This study will focus on the amount of VOCs present in commercially available beverages. The analysis will utilize the Atomx, an automated VOCs sample prep system with an in-vial purge, in conjunction with gas ...

Analytical Trap Comparison for USEPA Method 8260C
Abstract Purge and trap concentration is a technique that is used for the analysis of Volatile Organic Compounds (VOCs). The major component of any purge and trap system is the analytical trap. This trap is responsible for retaining the VOCs during the purge cycle and then releasing them upon heating and transfer to the GC/MS for separation and detection. While most standard methods define the ...

The spectral absorption coefficient at 254 nm as a real-time early warning proxy for detecting faecal pollution events at alpine karst water resources
Because spring water quality from alpine karst aquifers can change very rapidly during event situations, water abstraction management has to be performed in near real-time. Four summer events (2005–2008) at alpine karst springs were investigated in detail in order to evaluate the spectral absorption coefficient at 254 nm (SAC254) as a real-time early warning proxy for faecal pollution. For the ...

Waters and BioanalysisZone are Highlighting our Bioanalytical Chemists
Like the black panther, are analytical scientists going extinct? In a presidential election year, we are reminded of the many tough choices we face—Democrats or Republicans, plastic or paper, ketchup or mustard, soccer or football. And as we watched the Olympic track and field events, for instance, we saw the margin between first and last become more narrow with each subsequent heat. ...

Simple determination of haloacetic acids (HAAs) in potable water with ion chromatography hyphenated to mass spectrometry
Haloacetic acids (HAAs) are commonly produced as disinfection byproducts (DBPs) from water treatment processes. Some HAAs are regulated by the author- ities and have been classified as potentially carcino- genic. They have traditionally been analyzed by gas chromatography (GC), a technique that requires time-consuming sample extraction and derivatiza- tion, leading to higher costs per analysis. ...
