We arrange a wide range of specific injectors for matrices which cannot be introduced directly into the GC or GC / MS with standards injectors, for example high pressure injectors LGI of DaVinci for analyzing high pressure liquefied gas, injected directly to the column head. Or MyVAP systems of SRA Instruments that also allow the introduction of LPG on gas phase directly to the S/SL of GC or GC/MS injectors. We also arrange automated system like GICU for analysis of several lines of pressurized gas.
