Chemistry Reagent Methanol Optima™ LCMS Grade 99.9% 4 Liter

Novel gradient elution test with Photodiode Array Detector screens for UV-absorbing contaminants at every wavelength in the 200 to 400nm range to afford smooth baselines and to reduce interferences

Evaluated for 17 metal impurities at ppb concentrations to minimize the formation of metal adducts during analysis and simplify spectral interpretation

0.1 micron filtration minimizes troublesome particles that may interfere with LC/MS and UHPLC system performance and provides an ideal solution to prepare cleaner, particle-free mobile phase blends

Positive mode ionization (as propazine) and negative mode ionization (as mecoprop) with ESI and Single Quadrupole MS detect organic contaminants at max 100ppb and max 300ppb, respectively
