5.1 Checking the Performance and Specifications
Performance checking method is explained here.
The following items are required for performance check.
(1) Component Units of Liquid Chromatography System
•
Pump (Hitachi L-2100/2130 or equivalent)
•
Detector (Hitachi L-2400 or equivalent)
•
Data processing unit
•
Waste liquid bottle
NOTE
:
If deaeration of detergent is inadequate, full
performance may not be provided. In this
case, deaerate the detergent sufficiently of
connect it through a degasser.
(2) Items for Performance Check
Prepare the following items for performance check.
•
Load resistance coil
A coiled stainless tube with an inner diameter of
0.25 mm and a length of 10 m
•
60% methanol in about 1000 mL
A mixture of methanol 60% and distilled water 40% in
volume. This should be prepared separately.
•
Distilled water in about 500 mL
(3) Performance Check Parts Attached to Model L-2200
Autosampler
•
Standard sample
60% methanol solution of methylparaben
(Methylparaben 6 mg in methanol 60 mL + distilled
water 40 mL)
•
Sample vial, cap, septum
•
Standard rack
