摘　　要：戊醛中水分利用瑞士万通公司生产的916KF容量法卡尔费休仪测试,通过选择专用卡氏试剂、确定仪器最佳的滴定参数、确定合适称样重量,在密封状态下将样品注入工作介质中进行滴定,3min报出分析结果,多次进样结果重复性好,提高了分析效率,无毒无污染。The 916kf volumetric Karl Fischer apparatus produced by Swiss Wantong company is used for water in glutaraldehyde.By selecting the special Karl Fischer reagent,determining the best titration parameters of the instrument and determining the appropriate sample weight,the sample is injected into the working medium for titration under the sealed state,and the analysis results are reported in 3 minutes.The repeatability of multiple injection results is good,which improves the analysis efficiency,Non toxic and pollution-free.
