HPLC Methanol 1 L (Absolute)


HPLC Methanol (Absolute 200 proof) is purified, dried, and distilled in glass and guaranteed for lot-to-lot consistency and low UV absorption. HPLC grade Methanol is specifically purified for high resolution gas chromatography, trace organic analysis, critical and routine HPLC. Our HPLC Methanol meets all other ACS Specifications for General Use Reagent, Spectrophotometric Analysis and General Use HPLC. ProteoChem also offers ultra high purity LCMS Grade Methanol.

Applications for HPLC Methanol
HPLC Methanol is an ideal solvent for separation of peptides or proteins. ProteoChem's HPLC Methanol purity is ≥ 99.9% to maximize sensitivity of your assay. Our HPLC Methanol is a clear liquid packaged under nitrogen and provides sensitive low UV wavelength nondestructive peptide detection in HPLC.
