Hello Robert

I would have thought HPLC grade of solvent.

In the archive is there any reference to the procedure for cleaning
stainless steel gas supply lines and tubing for connecting the sample and
reference inlets? We may need to replace ours and also clean the S/S valve
assemblies on a MAT-253/Kiel carbonate device. We have an ongoing problem
with contamination.

Regards

John Hill
