Waters/432 Conductivity Detector - Verifying detector
Following the instructions for this in the manual, I set the temp to 35deg, then allow to equilibrate for 3 hours, base range set at 200, filter time response to fast, and pump 1mM KCl at 1.2 mL/min, it says I should be getting an output reading of 147 +/- 5. I am getting a consistent reading of 121. Any advice or help with this matter is appreciated. Advise this member.
