Description
PRISTINE® Methanol, LC-MS Grade, 4 Liter, 4/case
Ultra-Pure Solvent for Liquid Chromatography-Mass Spectrometry (LC-MS)
PRISTINE® LC-MS Grade Methanol is a premium, ultra-pure solvent designed to meet the rigorous demands of liquid chromatography-mass spectrometry and other high-sensitivity analytical techniques. With a purity level of ≥99.9% and minimal levels of metal ions and organic contaminants, this methanol grade delivers consistent, high-performance results in both quantitative and qualitative analyses.
Key Features:
- Ultra-High Purity: Engineered for purity at ≥99.9%, reducing background interference to enable accurate, reliable data in sensitive LC-MS applications.
- Low Metal Content: Minimizes ion suppression and enhances signal clarity by significantly reducing trace metals that can interfere with ionization.
- Consistent Performance: Every batch undergoes strict quality control to ensure reproducibility, supporting precise and consistent results across experiments.
- Applications: Ideal for LC-MS, HPLC, UV spectroscopy, and other analytical methods in pharmaceutical, environmental, clinical, and biotechnology research.
Trust Birch Biotech LC-MS Grade Methanol for unmatched purity, consistency, and performance—optimized for researchers who demand the highest analytical accuracy in their workflows.
