Cryogenic cold trapping is frequently used for narrowing the chromatographic band and improving the detection limit in Gas Chromatography. The cryotrap uses LN2 or CO2 for cooling, due to our low thermal mass the cooling is really fast. The CryoFocus has direct heating of the cooling chamber, resulting in amazingly fast heating of the trap.
After trapping, the analytes must be released from the cryotrap using a highly accurate and extremely fast heating, ensuring that they are introduced onto the column in a very sharp band. With a fast-heating cryo-trap better detection limit and better resolution can be seen on the detector.
Lately we have developed a new LN2 valve. Our in-house developed LN2 valve is silent and gives a better regulation of the low temperature.
