詳細

詳細

LiChrosolv hypergrade is accurately tested for LC-MS suitability, and meet 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.
