摘要:探讨水中油分浓度分析仪检定过程中萃取试剂对检定结果的影响。采用四氯乙烯替代四氯化碳作为萃取剂检定水中油分浓度分析仪,并与四氯化碳萃取剂检定结果进行比对,结果表明用四氯乙烯取代四氯化碳作为萃取剂,检定结果可以满足检定规程JJG 950-2012 《水中油分浓度分析仪》的相关要求,同时更加环保。
Abstract:The influence of extraction reagent on the verification result of analyzer for oil concentration in water was discussed. Tetrachloroethylene was used as the extractant to verifiy the analyzer for oil concentration in water instead of carbon tertrachloride. By comparison with the results of carbon tetrachloride extractant, it was considered that the calibration results could still meet the requirements of the regulation JJG 950-2012, and the extractant of tetrachloroethylene was more environmentally friendly.
