HH.

Confirm that the pH is >11. With the pH within this range, turn on the cell using the

carbohydrate standard quad waveform. Let the system equilibrate for 30 min.

2.6.3

Verification of Column Cleanliness

Once the columns are equilibrated, inject a system suitability standard such as the column’s QAR

standard, to establish the performance of the column at start-up. This chromatogram can then be

referred to when troubleshooting your system. Once you obtain the expected chromatographic

performance, you are ready to proceed to running your application.

Thermo Scientific recommends that the system suitability standard be run whenever you reinstall

a column after long-term storage.
