PRISTINE® Water, LC-MS Grade, 4 Liter, 4/case

Ultra-Pure Water for Liquid Chromatography-Mass Spectrometry (LC-MS) 

PRISTINE® LC-MS Grade Water is purified for the specific needs of liquid chromatography-mass spectrometry and other highly sensitive analytical techniques. With a purity level that minimizes ion suppression and interference, this water grade is designed for maximum sensitivity and accuracy in critical applications. Featuring ultra-low conductivity, low total organic carbon (TOC), and low UV absorbance, it is ideal for achieving reliable, precise results in both qualitative and quantitative analyses.

Key Features of Part # 1939-5:

  • Ultra-High Purity: Ultra-low TOC and ion content reduce background noise and ensure minimal interference in sensitive LC-MS assays.
  • Ultra-Low Conductivity: Provides ultra-low conductivity to prevent ion suppression, optimizing signal clarity and response.
  • Low UV Absorbance: Provides low UV absorbance, essential for methods requiring high clarity and sensitivity, such as UV detection.
  • Consistent Performance: Strict quality control delivers consistent performance across batches, supporting reproducibility in every analysis.
  • Applications: Ideal for LC-MS, HPLC, GC-MS, and other advanced analytical techniques in pharmaceutical, environmental, food safety, and biotech industries.

Optimize the precision and accuracy of your LC-MS workflows with Birch Biotech LC-MS Grade Water, trusted by laboratories for unmatched purity, reliability, and performance in sensitive analytical methods.
