Beschreibung

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
