The figure below shows a 60-minute trace of continuous injections of
caffeine and propyl paraben in 50% methanol/50% water.
Scaled trace of continuous injections with T1 changed to –60
The figure below shows a 5-minute scaled trace (or zoom) of the 60 minutes of
continuous injections shown in the previous figure. T1 is changed to –5. T2 is
changed to 0. AU1 and AU2 remain as “auto.”
Scaled trace for 5 minutes of continuous injections with T1 changed to –5
The figure below shows a 60-minute scaled trace similar to that shown in the
preceding figure titled “Scaled trace of continuous injections with T1 changed
to –60” with the starting absorbance or AU1 changed from auto to 1. T1
remains at 60. T2 remains at 0.
Scaled trace for 60 minutes of continuous injections with AU1 changed to 1
