ABSTRACT:
An improved Schiff's reagent for detection of aldehydes (such as formaldehyde and gluteraldehyde) contains a para-rosaniline compound (such as para-rosaniline hydrochloride), orthophosphoric acid, a bisulfite compound (such as sodium metabisulfite), a phosphate compound (such as sodium orthophosphate monobasic), and water. This reagent provides lower detection levels and faster results than the reagents of the prior art, and is particularly useful in testing the rinse solutions of reusable medical equipment (such as hemodialysis equipment).
