IC very high conductivity
Posted: Thu Feb 08, 2024 9:32 am
Hi,
I have very high conductivity near 7000 μS.
IC 5000+, AERS 500e, AS 11
food testing: phosphates, nitrates
Gradient method NaOH
A high level began to appear suddenly when moving the gradient from low concentration 0,5% NaOH to 50% - 50mM NaOH.
Has something damaged the suppressor!? Any contamination!? At 0.5% there is a very low conductivity of 0.5.
The first injections did not show such anomalies. I changed from aqueous solutions (fish and meat) to ashing (fish and meat; 550C) and dissolving in water.
