Achieving Low-Level Detection of Benzene in Beverages with an Automated Headspace Vial Sampler

Abstract

Eight commercially available beverage samples were selected for low-level detection of benzene by static headspace analysis. This study will use the Teledyne Tekmar HT3 Automated Headspace Vial Sampler to analyze parts per trillion (ppt) levels of benzene in beverages. A GC/MS system will be employed in full scan/SIM mode for separation and detection of benzene, as well as other volatile compounds.

 

Evaluating USEPA Method 524.3 Utilizing Newly Permissible Method Modifications to Purge and Trap Techniques

Abstract

Purge and Trap (P&T) concentration in conjunction with Gas Chromatography/Mass Spectrometry (GC/MS) is a widely used technique for the determination of Volatile Organic Compounds (VOCs). Due to the sensitivity requirements required with drinking waters, P&T is the recommended technique for VOC extraction. Recently, the United States Environmental Protection Agency (USEPA) approved an updated version to their drinking water method, USEPA Method 524.3. This new revision allows more flexibility in method operating parameters that take advantage of current P&T capabilities and have the possibility of increasing lab productivity. This application note investigates purge extraction volume variations and their respective affects on compound response.

 

Using Alternative Carrier Gas for US EPA 524.3

Abstract

Due to regional shortages and increasing costs of helium, the preferred carrier gas in gas chromatography, alternative carrier gas options are in ever increasing demand. This study will evaluate the Teledyne Tekmar Atomx Multimatrix Autosampler in conjunction with a Thermo Scientific TRACE 1310 / ISQ GC/MS, while employing hydrogen carrier gas and nitrogen purge gas to perform USEPA Method 524.3. A working calibration curve, precision and accuracy study (% Diff) and 4-bromofluorobenzene (BFB) tune evaluation will be presented to determine the validity of alternative gases to helium for EPA Method 524.3.
