Analyzing the GCMS amenable compounds in water matrices according to the European Water Framework directive ( 2013/39/EU)

Purpose: An overview of the results of GC amenable compounds is given for EU 2013/39/EU
Methods: For the volatile compounds headspace GCMS was used; for the semivolatiles liquid liquid
extraction was applied followed by GCMSMS detection.
Results: The detection limits are calculated by standard deviation and there are some linearity examples. Not all compounds are listed in this poster, but a full list is available.

An Innovative Injector Allows Helium Carrier Gas Conservation in Analytical Gas Chromatography

We introduce a new, innovative injector which allows conservation of helium carrier gas. While preserving the analytical GC column flow with helium, it maintains the septum purge and the split flows with another inert gas like nitrogen - even during the analytical run. The analytical performances of the injector are in line with those of the common split/splitless injector module

Automated, Rapid And Reliable Determination Of Dissolved Gases In Water By Static Headspace – Gas Chromatography

Purpose: Exploring the possibility to perform a quantitative determination of dissolved gases in water in a reliable and accurate way. Methods: The quantification of dissolved gases is performed by building a calibration curve spiking blank water samples with increasing quantities of saturated water followed by headspace sampling and GC/ FID analysis. Results: The results show good correlation factors and limit of quantification lower than 10ppb for the four gas analyzed.

Determination of Veterinary Drug Residues in Milk by GC/MS and GC/ECD

Purpose: Develop a rapid, sensitive method for determining amitraz and its metabolites in milk.
Methods: Samples were hydrolyzed in acidic condition and extracted with hexane. After derivativation, the samples were analyzed by GC-ECD or directly by GC-MS.
Results: The results show that GC-MS determination of amitraz and its metabolites is rapid and sensitive.
