LC/GC guy's question about USP water conductivity testing
Posted: Mon Aug 23, 2010 2:52 am
Hello all,
This question is kind of stray from LC, it is about the interval of conductivity cell verification, in USP chapter <645>, there is no clear requirement about the interval.
The vendor recommend that we just verify the cell constant on a weekly basis. Would you please share your experience with this?
Thanks in advance,
Terry
