Ethyle acétate 99,8 GC_ASSAY_METHOD, LiChrosolv®, hypergrade LC-MS, Supelco®
Ethyle acétate

LiChrosolv® hypergrade is accurately tested for LC-MS suitability, meeting 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.
