Description
Catalogue Number	100029
Synonyms	ACN, Methyl cyanide, Ethyl nitrile, Cyanomethane
Overview	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.
