Mobile Phase Additives
Mobile phase additives such as triethylamine, trifluoroacetic acid, and
ion-pairing reagents can compete with sample ions, decreasing sensitivi-
ty and, in some cases, reducing sample ion intake into the MS. To obtain
symmetric peaks and/or sufficient retention, use base deactivated, state-
of-the-art Type B silica packings that minimize the need for additives.
Assembles quickly and easily!
