i'm running an anionic analysis on dionex with gradient NaOH from 1.0 to 60 mm concentration. Analytical column is Ion Pac AS 11-HC 4x250 mm,9μm Dionex and guard column Ion Pac AG 11-HC 4x50 mm, 13μm Dionex. Suppressor is ADRS 600 4mm. When i performed the analytical method validation my conductivity was around 0.8 μS and now its around 1.8μS and it won't drop even with over weekend equilibration.
I have changed detector, suppressor, eluent generator, pump and still the conductivity is high.
Can someone help me solve my problem?
Thanks in advance
