摘要
采用特殊的取样装置 ,以气相色谱法测定尿素—甲铵液 (以下简称尿液 )中微量溶解氧。具有简便、快速、准确度高、测定重现性好等优点。其最小检测浓度小于 1× 10 -6。适用于对高温。
The trace dissolved oxygen in urea solution can be detected with gas chromatography and a special sampling equipment It has high degree of accuracy and the merits of being simple, fast and having good repeatability.Its least detection concentration is less than l×10 -6 which suits the fast detection of dissolved oxygen in high temperature and high pressure liquid phase
