High-Low Calibration with Inline Dilution (Metrohm IC)
Posted: Fri Jun 12, 2020 1:51 am
Hello,
We are trying to extend the calibration range of both our anion and cation calibrations to account for high concentration ranges in wastewater samples. We are currently running a Metrohm 940 IC with Inline Filtration and Inline Dilution.
Our current analytes of interest are as follows:
anions: F, NO2, Br, NO3, SO4, PO4
cations: Na, NH4, K, Ca, Mg
I would like to set up the high-low calibration technique as specified in the S349 Metrohm application note, but this is for Partial Loop injection, which we do not have. According to a webinar I watched delivered by Dr. Andrea Willie, I believe this technique is possible with Inline Dilution.
Can anyone confirm this for me and ideally send me any tips to set it up with Inline Dilution on MagICNet 3.1? I would be very appreciative of any assistance.
