Do I need Peltier cooling with the OPTIC inlet?

Solution

The OPTIC inlet is standard supplied with Air cooling. The Air cooling of the OPTIC is very fast because the OPTIC inlet has a very low thermal mass. The Air cooling can be used to cool the inlet till a temperature of about 30°C depending on the GC oven temperature and environmental temperature. In general it is easy to reach 45°C for the OPTIC inlet with Air cooling and the 45°C is reached very fast.

When inlet temperatures below 40°C are needed is is better to use a Peltier cooler or a Cryogenic solution. With the OPTIC Peltier cooler a temperature of 7°C can be reached. When the LN2 cooling option is used it is possible to reach -150°C and with LCO2 a temperature of -60°C.
