I wants to develop phosphorus chloride content on ECD, in starting i got constant response of phosphorus chloride peak, but now it's response was have variation not consistent, pls suggest
I have updated the tags on this post and will share the post with the applications forum on the Agilent community .
Sharing your instrument type and method parameters would be a help as well.
When you say constant response, do you mean of just the phosphorus chloride peak area or from the relative response to an internal standard?
Reason being is that your response will change over time if you are just looking at the peak with no internal standard. Ideally for GC with any detector you need an internal standard to normalise your peak area response as no injection into a GC is ever the same from a syringe.
