General description
Methanol, also known as Methyl alcohol, is a colorless organic solvent commonly used to dissolve substances with high and medium polarity. It is also used as a starting material/solvent for synthesis.
Application
Methanol is used as a solvent
- In the mobile phase to separate mercury species on a Zorbax C18 reverse phase column.
- To wash the cartridges and as an eluent to extract the analytes during the solid-phase extraction (SPE) process.
- A standard in the gas chromatography determinations of methanol content in alcoholic beverages.
Appropriate for trace environmental analysis.
Packaging
is packaged in 1L amber glass bottle
