一般描述

Methanol is suitable for isocratic HPLC, meets ACS specifications for testing USP/NF testing monographs. It is extensively utilized in High-Performance Liquid Chromatography (HPLC) due to its excellent solvation properties and high miscibility with both water and organic solvents, thus making it an effective solvent for preparing mobile phases that enhance the separation and sensitivity of analyte detection.

应用

HPLC, Meets ACS Specifications, Meets Reagent Specifications for testing USP/NF monographs
MX0475P-6 and MX0475P-1 are packaged in poly coated glass bottles
MX0475-NP10 is sold as 2 x 10 L
Methanol can be used as:
  • A solvent for the extraction of pesticides from soil samples.
  • An organic modifier in the quantification of esculin in pharmaceutical formulations via reverse-phase high-performance liquid chromatography (RP-HPLC).

包装
