Selection of applications for gas chromatography and liquid chromatography in petroleum product analysis
Thread Content
The laboratory wants to add a chromatography instrument, mainly to analyze the components of finished oils as well as trace elements such as sulfur and nitrogen. Since I have no experience with similar instruments before, I would appreciate it if experts could advise me on whether to choose gas chromatography or liquid chromatography I had looked at some relevant materials and standards before; it seems that gas chromatography is often used for oil testing in SH standards, but it appears to be suitable for measuring light components. Also, what is the feasibility of purchasing used instruments? The budget should not exceed 50,000: (Thank you everyone!) ! ! !
If the analysis of sulfur and nitrogen is required, it is recommended to use two chromatographs. For component analysis, a regular chromatograph is sufficient; it is necessary to select an appropriate detector, with TCD and FID being commonly used. To detect sulfur, an FPD detector is required, while to detect nitrides, a nitrogen-phosphorus detector equipped with a rubidium ball is needed; these two types of detectors are not conventional. Your 50,000 yuan is simply not enough to buy such a chromatograph.
It might be difficult to afford a chromatograph for 50,000 yuan.
You might want to check with Shandong Ruihong; it’s possible
Yeah, I’m worried, haha. Let’s do the research first and then let the boss make the decision; no need to worry about it:lol
Well, thank you. I’ll go check it out: handshake
:)Thank you, teacher. I didn’t know what to do at the time and so I didn’t reply :( In the end, I still didn’t buy it
