Thread Content
Help: Online measurement of methanol in a gaseous medium; the gaseous medium consists of 99% nitrogen, 0.5% water, and 0.5% oxygen. There is approximately 250 ppm of gaseous methanol. What analyzers do experts use to detect it?
1. Use an online chromatograph equipped with a FID detector. 2. Use a VOC analyzer, which also requires a FID detector. 3. Use an online gas infrared analyzer to detect the absorption of methanol. 4. Use an online TOC analyzer to measure the TOC after the sample is absorbed, and then convert this value into methanol content. 5. Use an online COD analyzer; similarly, measure the COD after the sample is absorbed and then convert it accordingly
Hello, are there any manufacturer recommendations?
I generally do not recommend manufacturers; if your company wishes to inquire about prices, it can carry out business activities through official channels.
