General description

LiChrosolv^® LC-MS grade solvents are specifically formulated to meet the stringent requirements of liquid chromatography-mass spectrometry applications. With exceptional purity, minimal impurities, and low evaporation residue, our solvents ensure reliable and reproducible results in complex analyses. Their excellent UV transparency and stable composition further enhance performance, making them the ideal choice for high-quality analytical outcomes. Designed to support a wide range of analytical workflows, LiChrosolv^® LC-MS grade solvents minimize potential interferences, empowering you to achieve the best possible results in your mass spectrometric analyses.

Now Available with Data Matrix Code

This high-quality HPLC-grade solvent now features a unique Data Matrix Code on its label, providing digital access to essential product information such as batch number, product number, and expiry date. Unlike standard barcodes, our DMCs feature a unique serial number for each bottle, enabling you to monitor and trace every bottle individually. With standard barcodes, all bottles from the same batch look identical. Our solution gives you true bottle-level traceability for greater control and compliance in the lab.
Know more about our data matrix code-labeled HPLC-grade solvents.
