OQ/PQ Operating Instructions
3.2.2
System Setup
The OQ/PQ procedure is similar for the different system configurations (e.g. NAN or CAP
configuration). However, some parts are different and depend on the system configuration
being tested (e.g. column, calibrator, connecting tubing, UV flow cell). Make sure that the
system is configured properly. Please refer to the UltiMate user’s manual for more
information.
In addition, several test parameters used with the tests are different for the individual
system configurations (e.g. flow rate, CRP value and injection volume). Refer to Section
3.2.1 and Chapter 6 for more details about how to setup CHROMELEON.
Note: Make certain that enough COM ports are available. For the Dual Gradient system
with flow sensors, the FAMOS and the Switchos 9 COM ports are required (including the
one required for the precision thermometer).
3.2.2 A
UltiMate System
To prepare the UltiMate system for the OQ/PQ test procedures 4.4 to 4.10:
a)
Switch on the UV detector at least 1 hour before starting the tests to warm-up the
instrument.
b)
Configure the system as required for the application (e.g. install the NAN calibrator
cartridge and NAN connection tubing for a proper NAN setup).
Note: If the system does not include a UV Detector, a standalone instrument is required to
perform the OQ/PQ procedures.
c)
Connect the appropriate restriction tubing to the port 6 of injection valve of the FAMOS
Microautosampler (‘column’ port). Use P/N 163933 for the NAN configuration and P/N
163934 for the CAP configuration.
d)
Use the Microtight union and appropriate PEEK sleeves to connect the restriction tubing
(360 µm O.D.) to the flow cell inlet (280 µm O.D.). Use P/N 161405 for the 360 µm
tubing and P/N 161498 for the 280 µm tubing (e.g. for the flow cell).
e)
Prepare the solvents as presented in TABLE 3-4, and start helium sparging to degas the
solvents. Thoroughly purge all channels.
TABLE 3-4
Required Solvents
Channel
Solvent
A
100% Water + 0.1% FA
B
99% Water + 0.1% FA + 0.8% acetone
(NAN)
99.5% Water + 0.1% FA + 0.3% acetone (CAP)
C
100% ACN + 0.1% FA (a)
D
100% Water + 0.1% FA
Note a) The acetonitrile is used to perform a wash step during the FAMOS test procedure 4.8.
CAUTION
Caution: Older revisions of the UltiMate system may be equipped with the
older type of the C and D solenoid valves (P/N160051). Due to their
limited resistance against strong organic solvents, do not expose these
valves to acetonitrile for a longer period than required to perform the wash
cycle of test 4.8 (e.g. not longer than 4 h).
