Description

4L LC-MS Acetonitrile / Advantages of products

  • Very low gradient peak, less than 0.8 mAU at 210nm, especially at 254nm, below 0.5 mAU, to minimize the interference of the gradient peak to the analysis results and improve the analysis accuracy.
  • Very low metal ion content, and the lowest metal ion content is less than 5 ppb.
  • Use three-level hydrolyzed borosilicate glass bottles to ensure sable quality.
  • Extensive application adaptability can fully meet, LC-MS/UHPLC/HPLC.
  • Very low content of organic impurities, the lowest relative baseline intensity in the mass spectrometry test is less than 2 ppb, which to the maximum extent reduces the influence of baseline noise and ion inhibition effect and ensures the high sensitivity of the analysis.
  • After 0.05 μm filtration process, the inert gas in the clean environment to ensure lower particulate matter content and non-volatile salt content.
  • Strict quality control, each batch of products throughLC-MS.Q-TOF-LCMS multiple analysis.
