Cooled Injection System Universal inlet for all injection techniques used in GC- and GC/MS

GERSTEL Cooled Injection System CIS Universal inlet for all injection techniques used in GC and GC/MS The GERSTEL Cooled Injection System is the most widely sold PTV-type universal inlet in the world. The CIS combines high performance with unique flexibility. The CIS readily adapts to all liquid injection techniques used in GC and GC/MS: Split & Splitless, On Column and Large Volume Injection (LVI). Thanks to the CIS and its Septum-Less Head (SLH), detection limits are lowered and the effort required for sample preparation is reduced. Due to the controlled programmed heating rate, analyte...

Important features and benefits of the CIS If the CIS is operated with GERSTEL ePneumatics, the MAESTRO Method screen provides an “at-a-glance” graphical display of all parameters including split ratio and resulting flows. Maximum flexibility • One inlet for all GC & GC/MS injection techniques • A range of cooling options to meet all user requirements: LN2, LCO2, Cryostatic and patented Peltier cooling enables multiple Headspace injections into the hot TDU combined with trapping in the cold CIS and splitless transfer to the GC column for best possible recovery and limits of detection. The...

Reliable and efficient routine analysis of matrix laden samples GERSTEL Automated Liner EXchange ALEX Dirty Matrix samples can lead to significant contamination of the GC inlet liner after just a few injections. Peak broadening, analyte discrimination and other matrix build-up effects can be the result of such contamination. This causes the quality of the analytical data to suffer. In order to avoid this, the inlet liner should be exchanged regularly. Liner exchange is a task that requires several manual steps, and the interruption of the analysis sequence, making it impossible to run...
