Fast GC-MS and GC-MS/MS methods require fast-cooling PTV injectors.

CHROMTECH developed the PFC option (PTV Fast Cooling), which can be retrofitted to all common (compressed air cooled) PTV injectors - Agilent, Gerstel, JAS, ATAS, Bruker...

Cryogenic media such as CO₂ or LN₂ are not necessary. The cold for the compressed air is generated and maintained electrically via Peltier elements.

At an oven temperature of 50°C, temperatures <5°C can be reached within 3 minutes (depending on the injector brand).
