Signal drop on carbon and sulfur channels
After calibration on 4 channels(high carbon/low carbon , high sulfur/low sulfur) of a CS-d instrument and testing some samples with 40 ppm and 90% carbon concentrations. after few days there was a huge signal drop in all channels so that 60 ppm is reported 0% . please advise a solution for this issue.
