Tubing connections
Legend
from eluent bottle via pump to pressure sensor
from pressure sensor via manual injection valve (6 Port 2 Position valve)
to sample loop selection valves (16 Port Multiposition valves)
from manual injection valve via column bypass valve (6 Port 2 Position
valve) and column to detector
from detector via fractionation valve (16 Port Multiposition valve)
to fraction bottle
to waste bottle
After installation of single devices according to their respective manual the GPC system ist set up. Lastly,
tubings are connected with the system as highlighted in diff erent colours.
Damage to Tefzel® capillary may occur when certain parts are used which are not suitable with Tefzel®. Do
not use stainless steel ferrule 1/16” in combination with stainless steel fi tting 12 mm UNF10/32 on Tefzel®
tubings, though both parts are included in the Accessory Kit for 6-Port/3-Channel Injection Valve (order
number F1357).

Note:
The inlet tubing of the AZURA® Pump P 4.1S included in FPGA is too short for the AZURA® GPC
Cleanup System. Use a longer inlet tubing included in A50041.
Note:
In case of a fl uctuating detector signal which results from degassing in the fl ow cell, use a tubing
with a low inner diameter of 0.25 mm between detector and fractionation valve.
