
The positioning of the UV lamp; sensitivity is best when the lamp is nulled. If the lamp is not correctly
positioned, more scattered light is produced in the fluorescence chamber that masks SO
2
response
as noise.

Contamination of the fluorescence chamber or sampling system; contaminants can either add to the
background noise, leach out SO
2
from the sample before it reaches the fluorescence chamber or
interfere with the fluorescence reaction.

Leaks in the system; leaks can either dilute the sample or change the flow rate.

Light leaks in the fluorescence chamber of the PMT housing; light leaks will increase the background
noise.

Condition of the membrane dryer; if the membrane dryer does not properly remove the moisture from
the sample, sensitivity decreases.
The overall sensitivity of the detector is expected to slowly decrease over time. This is mostly due to the
aging of the UV lamp and, to a lesser degree, the aging of the PM tube, the membrane dryer, and any
chemical changes that may happen to the fluorescence chamber coating due to reactions with the sample
stream. The sensitivity of the instrument should be restored with the replacement of the aged
components.
