Application

Aceticacid 100% can be used as a background electrolyte (BGE) in CE-MS (capillaryelectrophoresis is coupled to mass spectrometry) analysis of peptide digests.

General description

Aceticacid 100% is the most commonly used additive or solvent in LC-MS (LiquidChromatography-Mass Spectrometry) applications.
We are committed to providing greener alternatives that adhere to the 12 Principles of Greener Chemistry. This acetic acid is bio-renewable and produced from sustainably sourced beechwood, minimizing waste and promoting resource efficiency. Thus it aligns with ′Waste Prevention′, and ′Use of Renewable Feedstocks′.
