Brief introduction: PHX-2012 semi-automatic chemiluminescence immunoanalyzer is developed and manufactured by Plum Medical's Beijing Plang New Technology Co., Ltd. The medical equipment adopts Windows operating system and has the function of setting the parameters of the testing project. Characteristics: 1. The instrument uses Windows operating system, color graphical Chinese operation interface; 2. The chemiluminescence instrument has the function of setting the parameters of the detecting items. 3. Input mode: has the Chinese, the case citation letter input function, may input the concentration unit and the patient information; 4. This chemiluminescence instrument has the function of detecting: a. The instrument has two detection methods: single hole and double hole. b. Up to 12 items can be tested on an enzyme label board. c. Before testing, all kinds of functional holes can be visualized on the enzyme labeled plate. 5. Detection methods: the instrument has three methods: luminous value detection, qualitative detection and quantitative detection. Qualitative detection method: single critical value, double critical value, limit value detection, can set gray area. The quantitative detection methods include two-point method, linear regression method, point-to-point interpolation method, semi-logarithmic regression method, total logarithm method, ratio semi-logarithmic method and four-parameter method. 6. The instrument has the following quality control functions: Each quality control item can select 1-3 concentration quality control products, have immediate method L-J quality control chart method, can carry on the multi-rule judgment, the instrument can store, query and print the whole month quality control result;
