Capillary column problems
Thread Content
Previously, for the analysis of gasoline desulfurization, OV-1 type capillary columns and FID detectors were used. Now that we want to analyze the benzene-thiophene system, should we still use the same chromatography setup? If that doesn’t work, what kind of columns should be chosen? It’s best to use domestically produced ones
1. It is recommended that you get in touch with your current supplier of capillary columns. 2. Send in samples and observe the analysis results; you can judge for yourself whether it works. If not, I recommend using imported columns, as I am not very familiar with domestic ones

Old Ox talks a lot; you can make comparisons under the existing conditions, focusing mainly on whether the peak shape is correct. Secondly, OV-1 is non-polar, so you should check the polarity of the sample you are analyzing. If you’re not sure, you can contact the supplier – today’s suppliers all offer technical support services, and as long as you buy their products, they are likely to provide you with some useful suggestions.
