Setting Up The Inlet For Loop Injections (Flow Injection Analyses) - Thermo Scientific LCQ Fleet Getting Started Manual

Setting Up the Inlet for Loop Injections (Flow Injection Analyses)

Thermo Scientific
To set up the inlet for loop injections
1. Connect a loop filler to port 5 of the divert/inject valve. See
Figure 34. Divert/inject valve set up for loop injections
Connect port 3 to
the ion source
Connect a
loop filler to
port 5
2. Connect a sample loop to ports 1 and 4.
3. To connect the LC pump to port 2 of the divert/inject valve:
• Using an appropriate fitting and ferrule, connect one end of a length of red PEEK
tubing to the outlet of the LC pump.
To produce a stable solvent flow, the Surveyor MS Pump Plus requires a minimum
backpressure of 3 bar (43 psi). To connect the Surveyor MS Pump Plus, use a length
of 0.005-in. ID PEEK tubing sufficient to exert a backpressure of 3 bar (43 psi), or
connect an in-line backpressure regulator between the LC pump outlet and the
divert/inject valve.
• Using a fingertight fitting and a ferrule, connect the other end of the tubing to port 2
of the divert/inject valve.
