ASTM D4983-89(1996) Standard Test Method for Cyclohexylamine, Morpholine, and Diethylaminoethanol in Water and Condensed Steam by Direct Aqueous Injection Gas Chromatography
1.1 This test method covers the general considerations for the qualitative and quantitative determination of volatile amines such as cyclohexylamine, morpholine, and diethylaminoethanol in steam condensates and surface water by gas-liquid chromatography.2,3
1.2 This test method may be applied to water samples containing the amines in concentrations from 2 to 15 mg/L by direct injection of alkaline aqueous samples. Higher concentrations may be determined by appropriate dilution.
1.3 Although this test method is written for flame ionization detector, the basic technology is applicable to any highly sensitive nitrogen-specific detector provided water does not interfere with the measurement.
1.4 The test method may be extended to steam condensates containing low levels of these amines by adopting suitable concentration techniques such as steam distillation to bring the analyte concentration to an accurately quantifiable range.
1.5 The test method is applicable to other chromatographable amines by appropriately varying the chromatographic parameters. This must be validated by the individual analysts.
1.6 This test method has been used successfully with reagent-grade and boiler steam condensate waters. It is the user’s responsibility to assure the validity of this test method for any untested matrices.
1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
