Avanti LIPID MAPS Mass Spectrometry Internal Lipid Standards are designed to be “one time use items”. It is important to directly transfer from the ampoule to the experiment or prepare as a dilution for immediate use. Avanti cannot guarantee product purity and subsequent performance if used outside these guidelines.
Please note, if you need larger quantities of standards, all of our research catalog items are suitable for use as MS standards. Avanti can provide a Certificate of Analysis for all research products.
