# ICP Expert: Reagent blank correction

Hello everyone!

I was just wondering if it is at all possible to automatically correct a sample for its reagent blank in ICP Expert. Somehow this function is nowhere to be found in the software (or i looked with my eyes closed).
If the software does not support this function this means i have to take the signal intensity of both the sample and the reagent blank, substract them and then use the calibration function from the software into excel. This is mighty cumbersome especially when there are lots of samples. Am i missing something or is there an easier way to go about it?

If the signal from the blank is above the LOQ i can simply subtract the concentrations but if not so i do need to substract the intensity and subsequently interpolate the corrected intensity to obtain the corrected concentration.

I'm interested to see your suggestions!

• Okay turns out i didn't look hard enough. Under the QC tab, add a preparation blank and select the desired elements/lines for it. Then in the sequence tab you can select the option: Subtract preparation blank from samples and sample QCs.
