一、仪器简介 QGy—1型干涉仪是仿瑞利干涉仪设计的一种实验室仪器。它是利用比较受试物(气、液体)与参比物(已知折射率气、液体)的折射率差值来确定气体混合物或溶液成分的仪器,它也可用于测定气体或液体中微量杂质的含量。我部一些单位用它来测定火、炸药燃烧后气体含氮量和作气、液体成分分析及环境有毒气体含量测定用。该仪器采用一米气室时,测量折射率的近似精度可达2×10~(-8),测量范围为5×10~(-5)
First, the instrument profile QGy-1-type interferometer is imitation Rayleigh interferometer design of a laboratory instrument. It is an instrument that determines the composition of a gas mixture or solution by comparing the refractive index difference between a test substance (gas, liquid) and a reference substance (known gas, liquid refractive index), which can also be used to determine the trace amount of gas or liquid Impurity content. Some units of our department use it to determine the fire, explosives burning gas nitrogen content and make gas, liquid composition analysis and environmental toxic gas content determination. The instrument uses a meter air chamber, the approximate accuracy of measurement of refractive index up to 2 × 10 -8, measuring range of 5 × 10 -5,
