Hi,

Our Water UPLC columns count total injection and sample injections.

We are not sure they are counting correctly or how they are doing it.

Any idea how they do it? We cant find anything in the software or online...


Thank you all for your time and help.

Good luck on your challenges!
Mean while i end up finding out: it uses the vials.

More than one injection from the same vial spot in the same sequence counts like only one sample.

It does make sense.

Any way, thank you all for your time.

Good luck!
