223/2021 Gas Chromatography-Olfactometry (GC-O) is an essential technique in aroma analysis. Olfactory detection is often performed in parallel with GC detection, for example, using a mass spectrometer. To ensure that […]
LEARN MOREApp Note 213/2020 Stir Bar Sorptive Extraction (SBSE) coupled with gas chromatography-mass spectrometry and olfactory detection (GC-MS/O) allows for separation and identification of aroma compounds in complex sample matrices with […]
LEARN MOREGC-MS analyses of wine samples were conducted by a modified sequential-SBSE-GC-TOFMS method to compare concentrations of free and glycosidically bound smoke taint chemicals. Free volatile phenolics were determined by seq-SBSE-GC-TOFMS […]
LEARN MOREApp Note 3/2002 PTV inlets are often used for cryo-focussing and trapping of analytes for large volume, headspace, and thermal desorption applications. Selecting and optimizing trapping conditions for thermal desorption […]
LEARN MOREApp Note 8/2007 Reduction in analysis time is an important goal for easing the burden of large sample sets associated with routine screening of blood samples and sample sets produced […]
LEARN MOREApp Note 12/2012 16 phenolic compounds along with typical drinking water off-flavor compounds like geosmin, 2-methylisoborneol(MIB), and 2,4,6-trichloroanisole (TCA) were determined using two different approaches: 1) In-situ derivatization with acetic […]
LEARN MOREApp Note 8/2009 Accurate qualitative and quantitative analysis of perfumed or flavored products is essential to the flavor and fragrance industry. Especially when unknown samples need to be analyzed, traditional […]
LEARN MOREApp Note 5/2005 This paper applies SBSE coupled to thermal desorption (TD)-GC/MS to determine ultra-trace levels (sub-ng/L to ng/L) of compounds in aqueous samples.
LEARN MOREApp Note 5/2004 Analysts often encounter complex real-world sample types such as petroleum fractions or volatile polymer components. Resolving all individual compounds using a single chromatographic separation can be quite […]
