文献以KOH(NaOH)/H_2O_2-H_2-SO_4分别取代Ba(OH)_2/K_2Cr_2O_7,作为DFY-12型高速定碳定硫自动分析仪(下称仪器)的电导吸收体系,改善了测定条件并扩大测定范围.本文利用其测定法,对仪器的自动控制系统进行改装,采用自动预热—→自动给氧→自动读数→气路通断→程控指示等程序,与原自动线(自动放波一→自动加液→自动搅拌)组成一条更为完整的闭路程控测量自动线.只需按动一个搅拌开关,反应即可进行,80秒(可调)终端显示碳、硫读数,操作更为方便准确.
In the literature, Ba (OH) _2 / K_2Cr_2O_7 was replaced by KOH (NaOH) / H_2O_2-H_2-SO_4 as the conductivity absorption system of DFY-12 high-speed carbonization sulfur automatic analyzer Expand the measurement range.This article uses its determination method, the automatic control system of the instrument to be modified, using automatic preheat - → automatic oxygen → automatic reading → gas on-off program-controlled instructions and other programs, and the original automatic line → automatic dosing → automatic mixing) to form a more complete closed loop automatic measurement of measurement. Just press a mixing switch, the reaction can be carried out, 80 seconds (adjustable) Terminal display of carbon and sulfur readings, the operation more convenient and accurate .
