Descrição

General description

Methanol is a highly purified polar solvent widely used in analytical chromatography due to its low UV absorbance, high volatility, and compatibility with mass spectrometry. It ensures minimal background interference, making it ideal for trace-level detection in complex matrices.

Application

Methanol is used as:

• A solvent to prepare the Mobile phase for LC-MS/MS analysis.
• A solvent or reagent in chemical synthesis
• A solvent in work-up phase of chemical synthesis
• A disinfectant to clean laboratory space.

Packaging
