Mineral oil hydrocarbon (MOH) contaminants can be found in foods such as cereals, baked goods, fats and oils, coffee and many more. MOH can be introduced through process aids, additives, and machine- and lubricating oils used during food processing.

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.

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.

In this study, the GERSTEL PYRO was used for the pyrolysis of various materials that are relevant to forensic analysis applications, including paints, adhesives, and cosmetics. A GERSTEL MultiPurpose Sampler (MPS) was used in combination with GERSTEL PYRO...

Preparation of calibration standards and quality control samples are critical tasks in chemical analysis. The accurate and precise transfer of liquid standards and solutions is critical for ensuring the validity of analytical results. Automating the accurate transfer of liquid standards and solutions helps to improve the quality of the analytical procedure while freeing the analyst from performing tedious and repetitive manual tasks

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,...

Liquid-liquid extractions are used to extract and concentrate analytes from aqueous matrices. This extraction technique is widely accepted as shown by its inclusion within many official methods.

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,...

Laboratory samples are typically extracted prior to analysis by sensitive GC-MS or LC-MS/MS methods to separate the analytes of interest from the bulk of matrix components that could interfere with the analysis. Typical extraction methods include liquid-liquid extraction or solid phase extraction strategies

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...
