Assessment of 'cold Sterilog glutaraldehyde monitor'.
A new monitor, used in conjunction with an ultraviolet spectrophotometric difference method to determine glutaraldehyde concentration was tested with 2% alkaline solutions of varying concentrations and pH. Glutaraldehyde solutions with a concentration below 1.6% were rejected by the monitor, which reflected deterioration of glutaraldehyde quite closely, but failed to yield satisfactory results with fresh 2% alkaline solutions.
