CHEMetrics offers test kits employing the well-known PDMAB reagent to deliver sensitivity and accuracy within two minutes. Based on CHEMetrics patented Self-Filling Reagent Ampoule technology. Premixed. Premeasured. Precise. Each kit contains 30 tests.
The PDMAB Method
CHEMetrics' hydrazine test kits employ the PDMAB, paradimethylaminobenzaldehyde chemistry. PDMAB in acid solution reacts with hydrazine to form a yellow product. Results are expressed as ppb (µg/l) or ppm (mg/l) N2H4.

Hydrazine is a powerful reducing agent that is used in various chemical processes and in boiler water as an oxygen scavenger. To control corrosion, residual hydrazine typically is maintained in the 0.05 to 0.1 mg/l range. Higher levels may be used to guard against corrosion when the boiler is out of service for an extended period.
