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

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).

...
Grateful =)
thanks alot.
