Raman Astm Signal-To-Noise Test - Agilent Technologies 1260 Infinity User Manual

Raman ASTM Signal-to-Noise Test

These tests verify the Raman ASTM signal-to-noise for
• single wavelength (at signal) (EX=350 nm, EM=397 nm) or
• single wavelength (at background) (Ex=350 nm, Em=397 nm, dark value 450
• dual wavelength (EX=350 nm, EM
The specification single wavelength at signal can be measured with the Agilent LabAdvisor.
