HPLC grade MetOH ? - (Jan/25/2010 )

Dear All,

what is the difference between the usually used MetOH and the HPLC grade one ?

thanx in advance ;)


hplc grade is supposed to contain less uv absorbing contaminants.


thanks mdfenko :lol:

aaaah...and the reason is, not to interfer with detecting my analyte ...

does make sense...

right ?

thanx alot


exactly. but, keep in mind that the solvents used have their own intrinsic uv absorbance which precludes their use at lower wavelengths (eg-<210nm).
