|Pesticides in Foods using automated QuEChERS and LC/MS/MS|
Our Principal Gerstel, Germany has developed Automated QuEChERS Extraction for the Confirmation of Pesticide Residues in Foods using the GERSTEL MultiPurpuse Sampler MPS combined with LC/MS/MS analysis.
QuEChERS (quick, easy, cheap, effective, rugged, and safe) sample preparation methods are developed to help monitor pesticides in a range of food samples. These methods are quite labor intensive,since they include several manual steps, such as shaking, centrifugation, and dispersive SPE.
The dispersive SPE clean up of QuEChERS type extracts is automated using GERTSEL MPS XL Prep-station with Anatune CF-100 Centrifuge. Analytical methodology for confirming the presence of a variety of pesticides in a range food samples is developed using LC/MS/MS system.
The sensitivity and selectivity of LC/MS/MS enable sufficiently low limits of determination to meet acceptance criteria for reporting the maximum residue levels (MRLs) that are established by regulatory agencies.
|Static and Dynamic Headspace analysis of Alcoholic Beverages|
Our Principal Gerstel, Germany has developed Automated Static and Dynamic Headspace Analysis with GC/MS for Determination of Abundant and Trace Flavor Compounds in Alcoholic Beverages Containing Dry Extract.
Direct injection for gas chromatographic profiling of alcoholic beverages is usually preferable, but where spirits and liquors contain appreciable amounts of non-volatile material, some mode of pre-treatment may be required to avoid both inlet and column contamination. This consideration applies in particular to products aged for extended periods in wooden barrels and especially products containing added sugar, as volatile artefacts from sugar decomposition in the hot injection port can also complicate the chromatogram.
A combination of static and dynamic headspace analysis is used for profiling both abundant and trace compounds in beverages products. Static headspace is used with a tenax packed injection port liner for the abundant compounds. Dynamic headspace (DHS) uses an additional purging step to a second tenax liner which can then be desorbed to the same injection port liner used for the simple static headspace. In this case the previous abundant compounds are overloaded in the chromatogram but many additional trace compounds are now apparent. For both techniques the only sample preparation required is dilution of the sample in a headspace vial and relevant automated sequences in either static or dynamic mode are also run from the same autosampler rail. A PTV injector (GERSTEL Cooled Injection System CIS) in solvent vent mode is used in both cases for lowest detection limits.
Application of this combined approach constitutes an effective routine analysis protocol for this particular class of products while avoiding dry extract contamination.
