Question
Can the Hach PAN indicator solution be used to test wood for content of CCA (treatement)?
Summary
CCA (chromated copper arsenite) Indicator
Answer
Although Hach does not have a procedure for this, the procedure for this test calls for 0.1% (w/v) PAN indicator, which is the same strength of PAN indicator used in Hach low range manganese tests.
