5.3 Maintenance and service
5.3.1 Sample loop
The 889 IC Sample Center is equipped as standard with a 100 µL sample
loop. Other sample loops can be mounted. Please note however that the
correct combination of syringe and buffer loop is required in order to achieve
good results.
Observe the following when mounting a sample loop:
￭
Mount the sample loop at Port 2 and Port 5 of the injection valve.
￭
Adjust the configuration settings in the control software for the changed
sample loop volume.
Note
The maximum injection volume is calculated in accordance with the fol-
lowing formulas:
Full loop: Injection volume = Loop volume
Partial loopfill: max. injection volume = 0.5 × loop volume
µL Pickup: max. injection volume = (loop volume – 3 × needle vol-
ume) / 2
