Cary 630 FTIR - changing the desiccant

Hello all

I need to change the desiccant on our Cary 630 FTIR unit. Is there any detailed instructions and practical tips available as how to do this?

I ask as last time I did this, the desiccant became partially saturated as soon as it was installed.

I did purge the unit with N2 while changing the desiccant - was that the correct gas and thing to do. We don't purge the unit continuously during normal use.

One final question - should the Cary 630 FTIR unit be powered all the time. We tend to only connect it to power when it is going to be used.

Any help would be appreciated



  • Hi Kevin,

    As per above notes, you should keep it on when not in use to avoid mositure problem.

    If you will keep it off then there is high chance that desiccant discharge soon due to surrounding environment..
