2-Propanolo ≥99.9% (by GC), LiChrosolv®, hypergrade per LC-MS, Supelco®
Fornitore: Merck
|
Pericolo
|
Synonyms:
IPA, Alcool isopropilico
M-Clarity™ quality level = MQ100
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.
