LEARN MORESample clean-up steps, which are needed in order to prepare for example environmental or food samples for pesticide analysis, are time-consuming and a potential source of errors. Simplification or elimination […]
LEARN MOREThis study shows the use of the GERSTEL Cooled Injection System (CIS) a programmable Temperature Vaporization (PTV) type inlet for large volume injection of water samples and consequent trace compound […]
LEARN MOREFruit and vegetable extracts that are produced following the well established QuEChERS method typically contain a significant amount of nonvolatile matrix material. After several injections of such extracts into the […]
LEARN MORETypically membrane-assisted solvent extraction (MASE) is carried out off-line in a vial, from which the organic extract is transferred to a sample vial followed by large-volume injection (LVI). In this […]
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 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 MOREThis application note describes two automated methods for screening of extractable compounds from materials for food packaging, medical or technical purposes. The first method is based on automated liquid extraction […]
