In order to improve pyrolysis chromatographic analysis of materials that release polar functional groups e.g. carboxylic acids, a simple and rapid methylation method based on TDU pyrolysis/GC-MS in the presence […]
LEARN MOREThis study shows the use of the GERSTEL MPS/TDU/CIS with pyrolysis module for generating simulated thermal gravimetric mass spectrometry data (TGA-MS) of polymer samples. This mode of operation is also […]
LEARN MOREUltra-fast gas chromatographic methods for determination of the hydrocarbon oil index according to ISO 9377-2 were developed using a low thermal mass column heater (LTM). The column heater consists of […]
LEARN MOREIn this study we describe direct liquid injection techniques compatible with “dirty” samples containing non-volatile components. Using a glass liner that can be removed and replaced after the injection can […]
LEARN MOREThe determination of volatile and semi-volatile compounds in aqueous solutions using Stir Bar Sorptive Extraction (SBSE) as the extraction step is gaining acceptance in a wide variety of application areas […]

LEARN MOREExamples of optimized conditions for quantitation of residual hydrocarbons in polymeric packaging film and residual flavor components in recycled PET are shown. Techniques and equipment necessary for reliable calibration are […]
LEARN MOREThis paper describes an online LC-GC coupling system that allows fractions from an LC eluant stream to be transferred to a standard GC system. A large volume sampler equipped with […]
LEARN MOREThe combination of a new thermal desorption module with a cooled injection system (TDS-2,CIS-3, GERSTEL) now provides a powerful thermal desorption system for direct analysis of volatile trace compounds in […]
