Filming Amine (Aliphatic Amine) Test Kit & Refill Method Filming amines (aliphatic amine) are fed continuously into boiler feedwater to protect metal surfaces from corrosion caused by dissolved oxygen and carbon dioxide in condensate water. The amine forms a thin film on the surfaces that repels the potentially corrosive water. The Methyl Orange MethodReference: ASTM D 2327-80, Mono- and Dioctadecylamines in Water.CHEMetrics 3-minute procedure uses the standard methyl orange chemistry and features a unique extraction technique. The extraction eliminates several steps required in other procedures and provides increased sensitivity. The filming amine compound reacts with methyl orange to form a yellow-colored complex that is extracted into an immiscible organic solvent. Results are expressed in ppm (mg/L) octadecylamine. Options Filming Amine Test Kit 0-1 ppm Part#: K-1001 Minimum Detection Limit: 0.05 ppm Kit comes in a cardboard box and contains everything needed to perform 20 tests: Refill, Comparator, reaction tube with lid, tip breaking tool, and instructions. Refill Kit Part# R-1000 Applicable Refill Kit contains 20 self-filling ampoules and 20 double-tipped ampoules to refill kit K-1001 for the analysis of filming amines. R-1000 is compatible with C-1001 comparators.
