Response Problems

Low or no response problems are the most difficult to troubleshoot on the Agilent SCD and NCD as they may arise from one source or a combination of sources. Primarily, response problems are due to combustion problems, and Burner integrity should be investigated first.

It is beyond the scope of this supplement to deal with all possible chromatography related problems. The following table lists many of the common problems, their most probable causes, and the corrective action that should be taken. For further assistance contact Agilent.
