5.4.3 Equilibrating the Detector

After you have prepared the system, perform an equilibration for the detector. Make sure

that you set the gas pressure for the nebulizer before you perform an equilibration of the

detector.

1. Start the gas supply. Observe the gas supply requirements in section 3.1 and gas

supply guidelines in section 4.5.3.

Important: To prevent damage to the detector, do not exceed the

maximum gas pressure of 550 kPa (80 psig) for the gas

supply.

Always turn on the gas supply before starting the flow of

mobile phase. Wait at least 5 minutes before turning on

mobile phase flow.

Turn on the gas flow only when a nebulizer is installed

Important: Ne pas dépasser une pression de gaz maximaux de 550 kPa

(80 psig) pour l'approvisionnement en gaz.

Toujours couper l'alimentation en gaz avant de commencer le

débit de la phase mobile. Attendez au moins 5 minutes avant

de se tourner sur le débit de la phase mobile.

Activez le débit de gaz uniquement lorsqu'un nébuliseur est

installé.

2. On the detector display, from the Main Menu, select the Run Mode soft key. The Run

Mode Menu is displayed.

The gas flow will automatically start. Alternatively, you can establish the gas flow before

you start the acquisition in the Main Menu (→ page 49).

Adjust the settings and parameters as required for your analysis.

3. On the evaporation temperature screen, set the evaporation temperature. To optimize

the evaporation temperature for your application, observe the guidelines

in section 5.6.3 (→ page 66).

4. Start the delivery of the mobile phase. Monitor the fittings and tighten as appropriate.

Observe the guidelines for mobile phases and the flow rate specifications for the detector.

Tip: Make sure that you keep the flow rate within the specified range for the

detector (→ page 121). Operating the detector outside of these flow rates

may result in a loss of performance.
