Raman ASTM Signal-to-Noise Test
Raman ASTM Signal-to-Noise Test
This test verifies the Raman ASTM signal-to-noise for the FLD detectors.
Figure 59 Raman ASTM Signal-to-Noise Test (Lab Advisor)
Depending on the version of the detector the specification has changed.
Conditions: Standard flow cell (G1321-60005, G5615-60005), flow of
0.25 mL/min of water.

G7121B 500 / 3000 300
The Dark and Dual WL values are just additional specifications. Only the Raman value is
used for the standard instrument checkout.
The specification single wavelength at signal can be measured with the Agilent Lab
Advisor. All others (not used for standard checkout) have to be set up manually with the
information from Ta ble 2 4 on page 174 and Tab le 2 5 on page 174.
