Description

Description générale

We offer EMPARTA grade solvents for routine tasks in analytical laboratories. EMPARTA grade solvents offer fewer test parameters than EMSURE, yet are still of high quality. EMPARTA solvents meet ACS requirements, making them ideal for a wide range of analytical applications.

Application

• A technique based on infrared spectroscopy for determining sulfanilamide levels sustainably: Progress and comparisons of greenness and whiteness using ComplexGAPI, AGREE, and RGB.: This research introduces a sustainable method using methanol in infrared spectroscopy to measure sulfanilamide levels, highlighting advancements in green analytical chemistry (Lahkar et al., 2024).



• A novel method for quantitative determination of multiple substances using Raman spectroscopy combined with CWT.: The study utilizes methanol as a solvent in a new Raman spectroscopy technique to quantitatively analyze various substances, demonstrating enhanced precision in chemical analysis (Yang et al., 2024).
