Description

General description

EMPARTA solvents are designed for routine chemical synthesis, drying, purification, and critical labware cleaning in quality control environments. Engineered for precision, they deliver consistently reproducible results essential for rigorous validation and documentation.

Exceptional Quality Standards: These solvents meet or exceed ACS specifications, providing assurance of high quality that is crucial for accurate testing and analysis in quality control.

Consistent Reproducibility: Designed for precision, the solvents ensure that results can be reliably reproduced, which is vital for maintaining compliance and integrity in quality control processes.

Versatile Applications: Suitable for a variety of QC tasks, including analytical testing, method validation, and testing USP/NF monographs, these solvents support a comprehensive approach to quality assurance in laboratory settings.

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).
