o-Phthalaldehyde (OPA) Diluent Buffers
o-PHTHALALDEHYDE (OPA) DILUENT
|
Chromatographic Grade™
For preparation of o-Phthalaldehyde Reagents
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. | |
