Note: The peptide needle and additional mixers are not required to
perform the separations in this care and use manual. However, if
these components are already installed on the system from other
applications, it is not necessary to remove them. No changes in the
separation quality of N-linked glycans should be observed if these
components are installed.

Figure 1: Typical chromatogram of 2-AB labeled human IgG N-linked
glycans using the Glycan Performance Test Standard (Part No.
186003649).

This chromatogram is typical of the results obtained in Waters
laboratories with the method described above, using an ACQUITY
UPLC BEH Glycan, 2.1 x 150 mm , 1.7 µm column. The retention
times will be decreased by 33% on a 100 mm length column and
67% on a 50 mm length column, and the resolution of component
peaks will also be reduced proportionately, as shown in Figure 2.
Since these columns are all designed to be used with an ACQUITY
UPLC instrument which has low dead volume, high pressure and high
sensitivity, chromatographic retention times will be quite similar.
Variances will be due to system volume (e.g. the mixer volume) and
dispersion, column oven, and detector cell. This test is exceptionally
valuable for monitoring the life of the column and for trouble-
shooting separation difficulties that may arise.
