为了配合我所科研工作,遵照毛主席关于“独立自主,自力更生”的教导,我们试制了一台氢火焰、热导池两用气相色谱仪,使用情况良好。其电气部分采用了晶体管电路,结构简单,体积小,现介绍如下:(一)氢火焰电路氢火焰微电流放大器,一般采用静电计型或其他电子管型放大器。国外曾有用场效应管代替静电计管的报导,我们在此基础上设计了一台用场效应管与线性集成电路
In order to cooperate with our scientific research and follow Chairman Mao’s teaching on “independence and self-reliance”, we piloted a hydrogen flame and thermal conductivity cell dual-purpose gas chromatograph, which is in good condition. The electrical part of the transistor circuit, simple structure, small size, are described below: (a) hydrogen flame circuit hydrogen flame micro-current amplifier, the general use of static meter or other tube amplifier. In the past, there was a report that the field-effect transistor was used instead of the electrostatic meter tube in foreign countries. Based on this, we designed a field-effect transistor and linear integrated circuit
