1		G1362-87301	Restriction capillary

Turn ON the detector.

You are now ready to change the settings of your detector.
Connect the restriction capillary directly between the column compartment heat exchanger outlet and the in port of the detector.

Set up the instrument with the following test conditions.

**Table:** Chromatographic Conditions
Mobile phases	LC grade water
Column	Restriction capillary 2.7 m x 1.7 mm i.d.
Flow rate	1.0 mL/min
Compressibility	46
Stroke	20 µL
Stop time	20 min
Column compartment temperature	35 °C
Optical unit temperature	35 °C
Polarity	Positive
Peak width (response time)	0.2 min (4 s, standard)

Set the RID setpoints.

NOTE
The optical unit temperature must be set at least 5 °C above ambient conditions. Therefore if ambient temperature is above 30 °C higher values for optical unit temperature and column compartment temperature must be set.
Turn the heater ON and purge the detector reference cell for 20 min.
When purging has finished allow the baseline to stabilize.

NOTE
For optimum performance a stabilization time of 2 hours minimum is recommend.
Run the ASTM Drift and Noise Test Screen with the Agilent Lab Advisor (for further information see Online-Help of user interface).
Click OK.

The measurement starts.

The test has completed and shows either PASSED of FAILED.
