设计和试验了一种有效的富集方法,用镍丝涂上约2mgAPL,置水样中萃取痕量的二甲苯后迅速装在色谱仪的居里点裂解头内,裂解器控制一定的加热温度和时间,使样品随APL蒸发而气化进样并进行色谱测定,APL则冷凝留在预柱里。研究了一系列的因素对测定的影响。线性检出下限达到2ng/ml,相对标准误差±5％,本方法可以测定水样中一些痕量的有机物。 An effective enrichment method was designed and tested. Approximately 2 mg APL was coated with nickel wire. A trace amount of xylene was extracted from the water sample and quickly loaded into the Curie point pyrolysis head of the chromatograph. The cracker controlled a certain amount of heat Temperature and time, the samples were vaporized with APL vaporization and chromatographed, leaving the APL to condense on the precolumn. The effects of a series of factors on the assay were investigated. The linearity detection limit reached 2ng / ml, the relative standard deviation of ± 5%, the method can be measured in water samples trace of organic matter.
