In this application note, the flavor profile of five types of hops will be identified using Full Evaporation Technique (FET) Headspace on a Teledyne Tekmar Versa Automated Headspace vial sampler connected to a GC/MS (Gas Chromatograph/Mass Spectrometer) for chromatographic separation and detection. ...
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. ...
Introduction The Korean Standard Method for Drinking Water ES 04607.1 requires static headspace with GC/MS to monitor naphthalene. The Minimum Quantitation Limit (MQL) must be less than 3 ppb. ...
Introduction The Korean Method ES 04602.1b requires either static or dynamic headspace with GC/MS to monitor vinyl chloride, acrylonitrile, and bromoform. ...
Introduction The Korean Standard Method for Drinking Water ES 04603.2b requires static headspace with GC/MS to monitor 12 Volatile Organic Compounds (VOCs). The Minimum Quantitation Limit (MQL) must be less than 5 ppb. ...
Introduction The Korean Method ES 04601.2 requires static headspace with GC/MS to monitor 1,4-dioxane. The Minimum Quantitation Limit (MQL) must be less than 1 ppb. ...
The large number of samples and requirement for speed of sample processing mean that analysis needs to be conducted quickly, whilst giving reliable and accurate results. For analysis of BAC, headspace GC with FID detection is typically used. Headspace GC allows the quantitative analysis of alcohol directly from blood samples. Standard ...
This paper presents such a method, using gas chromatography with flame ionization detection fitted with a GS-Gas PRO column coupled with a headspace auto sampler. A practical limit of detection for methane of 0.9 mg L−1, with a retention time of 1.24 min, was obtained. ...
Environmental Protection Agency (EPA) has developed a standard method, namely EPA 524.3 to identify and quantify the purgeable organic compounds in finished drinking water by using purge-and-trap with GC-MS. Headspace with trap mode could serve as an alternative option in analysing the purgeable VOCs. During incubation, VOCs from water samples are effectively partitioned into ...
Abstract A static headspace method was developed using Teledyne Tekmar automated headspace vial samplers (Figure 1 and Figure 2) to meet the method requirements of the Alcohol and Tobacco Tax and Trade Bureau of the US Department of the Treasury (TTB) method SSD: TM:2001 for testing fusel alcohols in alcoholic beverages. ...
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. ...
Introduction This study focuses on the Versa Automated Headspace Analyzer and its ability to analyze Volatile Organic Compounds (VOCs) in water at the part per trillion (ppt) level. Read the full article Click ...
One of these qualifications, methanol content, is determined by EN 141103 , a headspace-gas chromatography method. This application note will present data for two different automated headspace vial samplers to meet the performance criteria outlined in EN Method 14110. ...
Introduction Police and forensic laboratories around the world routinely use headspace-gas chromatography for volatile components in biological fluids. One of the more common headspace analyses is the determination of blood alcohol in cases involving suspected DUI or OVI. ...

The combination of static headspace sample introduction and gas chromatography/mass spectrometry (HS/GC/MS) provides the analyst with a powerful, fully automated technique for the determination of trace volatile organic compounds (VOCs) in water. Samples may be hermetically sealed in the headspace vial at the point of sampling. This approach avoids errors due to ...
