GERSTEL Cooled Injection System – internationally the most frequently used PTV-type universal inlet, with patented septumless sampling head. Gas chromatographic analysis is now more versatile, reproducible and has lower detection limits than ever before, thanks to temperature programmed sample injection using GERSTEL Cooled Injection System. The CIS is easily and conveniently controlled from the GERSTEL MAESTRO Software – stand alone or through the Agilent Technologies ChemStation software.
