一般描述

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.

应用

Appropriate for trace environmental analysis.
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.

包装

is packaged in 1L amber glass bottle
