Argon gas intensity?

Dear Helios User,

We recently upgraded CyTOF2 to Helios. The standard protocol require that argon gas intensity has to be above 5 millions before tuning. But I usually can't get such high gas intensity although every connection parts are tight enough. sometimes after full protocol tuning, it can be over 5 millions, but sometimes not (Tuning can pass with Tb159 at about 1000K).
any suggestion to this gas issue? does this low gas intensity will affect data acquisition? signal intensity? Thanks!
