Preparation of the G7162A Refractive Index Detector, G7162B Refractive Index Detector

For best performance of the detector

• Turn on the heater in the optical unit and set it to the required temperature. We strongly recommend having the heater set to the same temperature as the column compartment. Let the optical unit equilibrate for at least a few hours (initial turn on of the module requires a longer time depending on the environment and the application needs).

• For high sensitivity measurements, a stable environment is required; refer to Environment. Prevent drafts from air condition systems.

• Do not work with removed/open front panels/doors. When the system includes a G1316 TCC (typically located below the detector) and its front panel is removed while the TCC is set to high temperatures, the up-streaming air could influence the stability of the detector baseline.
