General description

Methanol:Water30:70 (v:v) is a mixture of methanol and water. The key application ofmethnol:water mixture in analytical chemistry as a mobile phase in RPLC(reversed-phase liquid chromatography).

Application

Methanol:Water 30:70 (v:v) can be used as a mobile phase in the HPLC method:
  • For the quantitative determination of 3-hydroxybenzo[a] pyrene and 3-hydroxybenz[a]anthracene in the urine of PAH (polycyclic aromatic hydrocarbon) exposed workers.
  • For the extraction and quantification of hydroxymethylfurfural (HMF) and furfural in bread and bakery products.
