Perkin Elmer, N9304940, Water, LC/MS Grade, ≥99.9% (4x4L)

Our range of high purity LC/MS grade solvents, specifically optimized and tested for LC/MS suitability, ensure high-sensitivity analysis with minimal impurities and interferences. Designed for the most demanding UHPLC and MS applications, you can be assured of the following:   No LC/MS TIC signals higher than 50 ppb Reserpine (ESI+ mode) and 50 ppb 4-Nitrophenol (ESI– mode) Very low metal concentration Low particles (sub-micron filtered) Packaged in amber glass bottles with Actual Lot Analysis printed on each label QR codes on labels for quick access to SDS Our solvents are extensively QC tested to ensure the highest purity and lot-to-lot consistency. Testing Parameters Water LC/MS Grade Specification ESI+ mode (as reserpine) ≤ 50 ppb ESI- mode (as 4-nitrophenol) ≤ 50 ppb Fluorescence trace impurities ≤ 0.1 ppb at 450 nm emission ≤ 0.2 ppb at emission maximum of impurities Maximum UV absorbance λ: 200 nm  Amax: ≤ 0.01 Au λ: 250-400 nm  Amax: ≤ 0.005 Au LC gradient suitability/elution test ≤ 1 mAU at 254 nm ≤ 5 mAU at 210 nm Residue after evaporation ≤ 1 ppm Trace metal impurities (ppb) ≤ 5-50 ppb (depending on element – 18 elements tested)
