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)
- Also, Very low metal concentration
- Low particles (sub-micron filtered)
- Additionally, Packaged in amber glass bottles with Actual Lot Analysis printed on each label
- QR codes on labels for quick access to SDS
Furthermore, our solvents undergo extensive QC testing to guarantee the highest purity and lot-to-lot consistency.
