The derivatization of primary amines with o-Phthalaldehyde
and a mercaptan requires basic conditions. To
ensure the optimum pH of the reaction it is
important to use the correct diluent.
Three application specific diluents are
available : CB910 and GA104 for carbamate and
glyphosate analyses, and OD104 for analysis of
amino acids and other amines.
These borate buffers are produced from
starting materials which are free of heavy
metals and amines. As with most other products
of Pickering Laboratories, the quality of the
OPA Diluents is verified by actual post-column
HPLC analysis.
