30m*0.53mm 水、土中有机磷农药测定OV-17毛细管柱的详细资料
水、土中有机磷农药测定OV-17毛细管柱
名称:毛细管柱
固定液:50%苯基甲基聚硅氧烷
规格:30m*0.53mm
型号:OV-17
应用:GB/T 14552-2003 水、土中有机磷农药测定的气相色谱法
浩瀚色谱(山东)应用技术开发有限公司提出了固相萃取分离-毛细管柱-气相色谱法测定水中11种有机磷农药的方法。水样经固相萃取小柱分离并净化,甲醇-丙酮(70+30)混合液洗脱。用OV-17色谱柱(30m×0.53mm)分离,脉冲火焰光度检测器检测。11种有机磷农药的质量浓度均在5.00μg·L-1以内与其峰面积呈线性关系,测定下限(10S/N)在0.03~0.05μg·L-1之间。方法用于地表水样和饮用水样分析,加标回收率在65.7%~124%之间,测定值的相对标准偏差(n=6)在1.8%~9.9%之间。

Determination of Organophosphorus Pesticides in Water and Soil by OV-17 Capillary Column
OV-17 capillary column for the determination of organophosphorus pesticides in water and soil Details:
Name: capillary column
Fixative: 50% phenylmethylpolysiloxane
Specifications: 30m*0.53mm
Model: OV-17
Application: GB/T 14552-2003 Gas chromatographic method for the determination of organophosphorus pesticides in water and soil
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. proposed a method for the determination of 11 organophosphorus pesticides in water by solid-phase extraction separation-capillary column-gas chromatography. The water sample was separated and purified by solid phase extraction cartridge, and eluted with methanol-acetone (70+30) mixture. Separated by OV-17 chromatographic column (30m×0.53mm), detected by pulsed flame photometric detector. The mass co
