General description
This bio-based solvent for LC-MS offers the same precisionand reliability you trust, now with more sustainability.
LiChrosolv® hypergrade is accurately tested for LC-MS suitability and meets all the requirements of modern LC-MS ionization methods (ESI/APCI - positive and negative mode). Thanks to their low level of ionic background and low ion suppression, LiChrosolv® hypergrade solvents provide high reproducibility and high ionization efficiency. The packaging material has been improved to meet LC-MS quality requirements perfectly.
- Derived from renewable feedstocks with bio-carbon content certification
- Similar chromatographic resolution, reproducibility, and baseline stability
- Drop-in replacement: no method redevelopment required

Other Notes
Bio-Based LC-MS Solvents
LiChrosolv® bio-based solvents are derived from renewable feedstocks and verified through bio-carbon content certification. They provide comparable chromatographic performance to conventional solvents; same resolution, reproducibility, and baseline stability; and function as drop-in replacements requiring no method redevelopment.
Available with Data Matrix Code
This high-quality LCMS-grade solvent now features a unique Data Matrix Code on its label, providing digital access to essential product information such as batchnumber, 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.
