Hi! I need to know if it is possible to use liquid or gaz chromatography to analyse mercaptans in White spirit, and the different conditions for this method. Thanks advanced

Hi! I need to know if the Silver Nitrate method, used to determine the mercaptan sulfur content in moter fuels and other volatile distillates, is valid for low concentrations of mercaptan (<20 ppmw) I need a reply as soon as possible Many thanks advanced!

Can you advice about the best type of adsorbant commonly used to adsorb mercaptans from light hydrocarbon products thanks advanced.

many thanks for your help, I have had contacted NORIT by e-mail but I don't yet received any information.

the type of activated carbon I use is NORIT RB03

can you indicate me the best method to regenerate an activated carbon which is saturated with mercaptans ( ethyl, methyl et propyl mercaptans) thanks advanced!

I've a solution of White-spirit with a known concentration of mercaptans and I want to vary this concentartion by dilution; the problem is that I have not a pur White-spirit for this. I would like, so, to know if there is an other solvant with which I can dilute my solution. thanks advanced.

I would like to know if there is a difference between an adsorption isotherm which is determined by varing the concentration of the adsorbate with a fixed masse of adsorbant, and the opposite.

I'm just starting a project about removing mercaptans (methyl, ethyl et propyle mercaptans) from Wite-spirit using fixed-bed adsorption. I realy need information about this subject ( adsorption isotherm, breakthrow curves, optimal temperature and pression, the best analytical method ...)
