Dear All,

I have the following issue:
I have a four-component mixture which is analyzed by HPLC-ELSD. I do external calibration by injecting different volumes. I also do the same for the unknown samples. After the calibration, I always do the checking whether the compounds fall on the calibration range or not or the detector doesn't cut the signal.
I would like to write a custom field to have visible information about this information whether the analyzed compound fall into the calibration range or not. I know boolean or enumerated custom fields can work.

Unfortunately, I cannot identify "the calibration range and the maximum signal response of the detector" in the calculated formula entry. They are not in the list.

What I would like to see to have an extra column past the identified peaks with the following:
- Accepted
- Cut by detector
- Outliers (out of calibration range)

Do you have any idea ?

Thank you in advance!
Tomi
Hi ,
Maybe try using MAX( function with ENUM(EQ, LTE and GTE with value 0 = accepted , 1= Cut off and 2 = Outlier
Sorry not in front of Empower at the moment
Hy,

Okey, but how do you identify the signal limit of the detector and the actual calibration range (min and max) ?

Thanks !
You may have to find the max slice area from the raw data file - not sure what the field name for that would look like.
Thanks,
DR
