1,4-Dioxane is a chemical contaminant formed in trace amounts as a byproduct during the manufacturing process of detergents, foaming agents, emulsifiers and some solvents, which are widely used ingredients of commercial products such as soaps, detergents, shampoos, cosmetics, and cleaning agents.
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 an Olfactory Detection Port (ODP) is installed properly and is in good working condition,...
Direct thermal extraction (DTE) is a thermal desorption technique in which a small amount of sample, typically 10-50 mg, is placed in an empty fritted thermal desorption tube or into a small vial (μ-vial) within an empty thermal desorption tube.
The ability to perform accurate qualitative and quantitative analysis of perfumes or flavored products is essential to the flavor and fragrance industry. Especially when unknown samples need to be analyzed, traditional methods of GC analysis often lead to only qualitative results and...
This study shows the analysis of a commercially available personal care product using the GERSTEL MultiPurpose Sampler (MPS) configured with Thermal Desorption Unit (TDU), Cooled Injection System (CIS) PTV-type inlet, Dynamic Headspace (DHS) and pyrolysis (PYRO) modules...
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 methods of GC analysis often lead to only vague results and often require time consuming...
Aroma Office 2D (Gerstel K.K.) is an integrated software approach for simultaneous processing of retention index (RI) and mass spectra (MS) for rapid and improved identification of flavor/aroma compounds.
Static headspace analysis is often considered to be useful only when the analytes of interest are present in high concentrations. Although techniques like solid phase microextraction (SPME) and dynamic headspace (DHS) have better extraction effi ciencies, due to advances in mass spectrometry design,...
In this study, Thin Film Solid Phase Micro-Extraction (TF-SPME) devices with carboxen/polydimethylsiloxane (CAR/PDMS), divinylbenzene/polydimethylsiloxane (DVB/PDMS), and hydrophilic lipophilic balanced/polydimethylsiloxane (HLB/PDMS) coatings are investigated for their usefulness...
Stir Bar Sorptive Extraction (SBSE) coupled with gas chromatography-mass spectrometry and olfactory detection (GC-MS/O) allows for separation and identifi cation of aroma compounds in complex sample matrices with minimal sample preparation time.
