Full form of Mobile Phase MOC

[S.M.PANDYA]

Dear Experts

Can anybody guide me if HPLC method indicates about Mobile phase is MOC then what should be the mobile phase . Is MOC is a short form of any mixture of mobile phase ? If yes please advise me the detail.

Doesn't ring any bell as abbreviation for mobile phase solvent/additivies... The closer I could come at is "Metal Oxide Chromatography"... which can give some indicatations of the nature of the mobile phase additives used...

looking around on google :

Perhaps it deals with Fast Moc solid phase procedure ( developped by ABI) , in the field of peptides amino acids etc...

Could you give some more info about the HPLC methods or its references , it would help us to guide you

regards

Dear philippe

Thanks for yr reply .

Detail I have is only as below .

Column : TSK GEL 250mm

Mobile Phase : MOC

Wavelength : 274 nm

Column : TSK GEL 250mm

Mobile Phase : MOC

That is virtually useless. TSK makes dozens of columns called "TSK GEL", and MOC is not a standard abbreviation as far as I know. You need to contact whoever sent you the method and get more details.

I agree with Tom...

Maybe in this case (as probably it is a SEC method) MOC means "maximum organic concentration"
