I have been able to cool the oven perfectly fine providing the GC is contained within a fume cupboard. However if performed in a lab with "average" ventilation the volum of CO2 exhausted from the GC becomes so great it goes over the 8 hour and 15 min working limits (at about 15C).
Are there any other methods available that could achieve sub-zero temperatures without the need for large volumes of CO2 (or any other asphyxiant gas) to be injected into the GC oven?
Alternatively does anybody know of any methods available that will separate COS and SO2 at ppb level in bulk CO2?
