Note If you don't see spectral features in this window, inject a sample that is at a
higher concentration (2 to 10 times higher than the previous one) and collect the data
again. If you are using a split injection technique, you can also decrease the split ratio
so a higher concentration of the sample goes onto the GC column. For example, if
you were using a 100:1 split ratio, try changing it to 20:1.
9. To display a spectrum collected at a particular time, first select the spectral cursor tool...
...and then click the desired time location in the profile in the time response display.
Here is an example showing the cursor located at the top of a peak in the time response
display and the corresponding spectrum in the spectral data display.
