Determination of Furan in Coffee by Static and Dynamic Headspace-GC–MS
Abstract Coffees have aroma and taste based on where the beans are grown, roasting techniques, and flavor additives. One component of the bean responsible for the aroma and some of the taste are volatile organic compounds (VOCs). Furan is one VOC that has recently been investigated in food (1). An FDA method for furan in food uses static headspace and requires 30 min of incubation time at 60 ...

Two Headspace Solutions for the Analysis of Dissolved Gases in Water by Method RSKSOP-175
Abstract Dissolved gas analysis has been performed using a simplified headspace method following US EPA method RSKSOP-175. This method describes the preparation and analysis of dissolved gases in water. Recent developments in natural gas drilling from deep underground shale formations, using techniques such as hydraulic fracturing, have renewed interest in this method to determine dissolved gases ...

An Alternative Method to RSK 175 using a Purge and Trap Concentrator and GC/FID
Abstract With the growing price of oil, many alternative energy sources are being explored. Natural gas prices are actually decreasing, in large part to the use of hydraulic fracturing in areas like the Marcellus Shale in Pennsylvania. Due to increased concern over the hydrofracturing process and the release of methane and other chemicals into the local drinking water, a need has developed for ...

Meeting the Korean Method ES 04605.3 for Formaldehyde with Static Headspace GC/MS
Introduction The Korean Standard Method for Drinking Water ES 04605.3 requires static headspace with Gas Chromatograph/Mass Spectrometer (GC/MS) to monitor formaldehyde. The method is based on the derivatization of formaldehyde with O-(2,3,4,5,6-pentafluorobenzyl) hydroxylamine (PFBHA) to form the pentafluorobenzyl oximine compound within a static headspace vial. The method requires that the ...
