A report on an initial comparative study of two methods for the determination of glutaraldehyde.
Two methods for the determination of aqueous glutaraldehyde, a gas chromatographic method and an ultraviolet spectrophotometric difference method, were compared. The two methods gave similar results for glutaraldehyde concentration determination when investigating undegraded samples. However, the ultraviolet method gave lower values than the gas chromatographic method when degraded samples were studied. A possible source of these discrepancies is discussed.
