[labnetwork] CO2 purity for CPD?

[DeRose, Guy A.]

Mariusz,

In my lab, we use “Coleman Instrument grade” 99.99% CO2 in an aluminum cylinder with a dip tube.  We have found that the aluminum cylinders are much easier to handle than the steel ones due to reduced weight, and much cleaner to have inside the lab.

Subject: [labnetwork] CO2 purity for CPD?

Dear LabNetwork,

I would like to investigate what purity of CO2 is being used for Critical Point Drying (CPD) of MEMS in various labs. Could I please ask for a reply with a comment if you are using CPD? Did anyone investigate if there are significant benefits of using  5N over 3N purity of CO2?

Cheers,
Marius
