GERSTEL
10 important reasons why you should choose a GERSTEL CIS
Universal inlet   Only one inlet for all injection techniques
Septumless sampling head  

No contamination by septum particles; no loss of analytes from septum bleed; low-maintenance

Patented heating system   Optimal transfer of analytes to the column, even thermally labile substances, due to programmable linear heating; improved separation performance due to resulting small peak band width
LCO2, LN2 or patented Peltier cooling   Fast operation cycle time; cost-effective Peltier cooling eliminates need for external coolants when not necessary    
Elimination of solvent peak   Better chromatographic separation; protection of the capillary column and detection systems
Large volume injection of up to 1000 µl   Reduced detection limits and time savings due to less sample preparation time
Selective extraction of high or low boiling compounds  

Selective transfer of components to the column

Control by means of GERSTEL-MAS controller   Cost-effective system upgrades to other GERSTEL modules
Can be retrofitted to existing GCs  

Suitable for almost all GC models; a new GC is not required

Uses GERSTEL-GRAPHPACK®  technology  

Reduces system leaks and maintenance; extends column life and increases sample throughput
