Answer
Cause1: The light paths of the hollow cathode lamp and the deuterium lamp do not coincide. (When the BGC-D2 mode is set)
Corrective Action1: Adjust the position of the deuterium lamp. Click here for Replacing the Deuterium Lamp
Cause2: Light radiation derived from the flame or sample is exerting an influence.
Corrective Action2: Carry out a line search while spraying the blank solution.
Carry out a line search while spraying the standard sample at the maximum concentration in the measurement range, and then perform auto zeroing while spraying the blank solution.
Adjust the C2H2 flow rate and the burner angle.
