Hello,

I am trying to check the status of the optical system in an atomic absorption spectrometer by using it in emission mode.

The model i am working with is a XplorAA Dual (GBC Scientific) system. Currently, we do not have a hollow cathode lamp to test the equipment, but i was told that it could be used in emission mode to check the status of the burner and/or optics before acquiring a HC lamp. The problem is i can't seem to find the information regarding the configuration of the equipment for its use in emission mode. The manual provided doesn't seem to include this information, although i was able to find the configuration option for emission mode in the software.

We also have problems with the installation of the flame shield, it seems some parts are missing or there is something we are not seeing.

GBC Scientific doesn't have an official representative in my country (Argentina) anymore. I have tried to make contact with the technical service in Australia and other Latin american countries to no avail.

If someone familiar with this brand and/or model can help me solve these issues, it would be greatly appreciated.

Best regards,
