Perkin Elmer, N9304938, Methanol, 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.
