Rapid sample preparation methods for the analysis of Polycyclic Aromatic Hydrocarbons (PAHs) in seafood were evaluated using GC/MS/MS as the determinative technique. Three preparation techniques were studied: a) QuEChERS (Quick, Easy, Cheap, Effective, Rugged, and Safe) extr...

IntroductionFor some GC applications, the possibility to inject sample volumes as small as 10-20 nanoliters is extremelyattractive. This is particularly true with very concentrated samples, such as essential oils, where the mainconstituents easily overload the capillary column even at the highest ...
A minimum penetration depth in the injector (cold needle mode) is set, and 0.3 µL of air is automatically withdrawn after the sample to ensure that the part of needle inserted into the injector is empty. A 3 mm i.d. upper-tapered empty liner with an 8 mm long and 1 mm wide ...
