由洛阳石油化工工程公司研制的,适用于天然气、煤气、石油气中硫化氢含量测定的GD-101型在线分析仪,于1992.05.20在洛阳通过了中国石化总公司组织的技术鉴定。该仪器采用“返滴定原理”用纸带光度法测定硫化氢含量,采用计算机技术使之自动化程度高,测量范围比国外同类产品宽,不增加硬件可同时测量样气中的水份。该仪器在以下方面有独创性:1.用电解法产生标准硫化氢气体进行标定,具有结构简单、浓度准确、使用方便,控制灵活等优点。2.用红外光电检测技术制成微型光电检测头,体积小、热量小、信号大、操作方便。鉴定测试结果表明:性能稳定可靠,各项指标均优
The GD-101 on-line analyzer developed by Luoyang Petrochemical Engineering Company and applied to the determination of hydrogen sulfide content in natural gas, gas and LPG passed the technical appraisal organized by China Petrochemical Corporation in Luoyang on January 5, The instrument uses the “back titration principle” with strip photometric determination of hydrogen sulfide content, the use of computer technology to make it a high degree of automation, measuring range wider than similar foreign products, without increasing the hardware can simultaneously measure the sample of water. The instrument has the following ingenuity: 1. Electrolysis method to generate standard hydrogen sulfide gas calibration, with a simple structure, the concentration accuracy, ease of use, control and other advantages. 2. With infrared photoelectric detection technology made of micro-optical test head, small size, small heat, large signal, easy to operate. Identification test results show that: the performance is stable and reliable, all indicators are excellent
