Multicolumn Tandem 2-D Affinity Templates
Tasks
1. Insert a second column switching valve (referred to as the loop
valve) near the sample inject valve on the NGC instrument and map
as C2
2. Short length of tubing from port F on the sample inject valve to the
left inlet port on the loop valve (C2)
3. Short length of tubing from port E on the sample inject valve to the
right inlet port on the loop valve (C2)
4. One 5 ml loop tubing for each affinity column to the top and bottom
ports on the loop valve (C2)
For example, if you have two affinity columns
 Attach loop tubing to Column Top port 1 and Column Bottom
port 1
 Attach loop tubing to Column Top port 2 and Column Bottom
port 2
5. Tubing from port 2 on the outlet valve to the syringe port on the
sample inject valve
6. Affinity columns at ports 1–4 on C1
7. Desalting or SEC column at port 5 on C1
