General description

EMSURE grade solvents are suitable for a broad spectrum of classical lab applications, and are frequently used in regulated and highly demanding lab applications. EMSURE provides worldwide best and most extensive product specifications. We declare our EMSURE range to be in compliance with the ACS, with the reagent part of the European Pharmacopoeia (Reag. Ph Eur) and also with the ISO standards.

Application

Methanol can be used as a solvent for the extraction of:
  • Bioactive compounds in bottle gourd using gas chromatography-mass spectrometry.
  • Antioxidants in lotus rhizome through centrifugation.
It can also be used as a reactant in the direct synthesis of dimethyl carbonate from CO2.

Features and Benefits

  • Most extensive specifications worldwide
  • Tested for up to 70 parameters
  • Extraordinary purity
  • Very low limiting values
  • Greater accuracy and control of analyses
  • Optimized for highly critical and demandinganalyses
  • Ideal for method development
  • No interference or contamination due tounknown impurities
