Hi, all.

I have a question for quantitative analysis with react IR (PAT).

I understand that the calibration curve should be drawn before the quantitative analysis with react IR.

My question is, do I have to draw a calibration curve every time I use react IR? Or once I draw it, can I still proceed without calibration for several days or weeks?

For example, in the case of pH meter, calibrating every day is good before we use it, but there is no big difference in the results even if we do it once a week.

Once the react IR is installed in the reactor, it is not easy to remove it again to draw the calibration curve, so calibration cannot be drawn every day. Thus, if the sensitivity of reactor IR is very different that day, we should consider not using reactor IR at all. I want someone to answer this question. Thank you in advance!
