LiChrosolv® hypergrade is accurately tested for LC-MS suitability, and meets all the requirements of modern LC-MS ionisation 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 ionisation efficiency. The packaging material has been improved to perfectly meet LC-MS quality requirements.
