PDA detectors?

hello,

Can someone please explain the purpose of purging PDA detectors - is it to flush out any residual contaminants/samples from previous run before starting a new run?

As far as I know, the detector should be purged for max. 30 minutes before autozeroing it before purging again.


Please help.
Thanks!

I didn't find the right solution from the Internet.
