has been selected, the peak ta-
ble can be customized on the user's choice. After clicking the
button, the following columns can be included in the
peak table.
number
Peak number.
retention time Retention time of the component (in min-
utes, irrespective of the chosen retention
units on the chromatogram graph axes).
The total value in the column is equal to the
chromatogram duration.
halfwidth Width of the peak at half height (in min-
utes).
height Height of the peak (in mV). The total value
in this column is the sum of heights for all
identified peaks.
height% Normalization of peak heights for all peaks
using the NORM value entered in the
Total

area Area of the peak. Depends on the units on
the X and Y axes of the chromatogram. The
total value in this column is the sum of ar-
eas for all identified peaks (including uni-
versal component).
area% Normalization of peak areas for all peaks
using the NORM value entered in the
Total

capacity factor
The capacity factor k'
i
of the component is
equal to the ratio of its corrected retention
time (t - t
0
) to the void time of the system t
0
:
k'
i
= (t
i
- t
0
) / t
0
Total for this column is equal to the capac-
ity factor of the last peak of the chroma-
togram.
resolution Resolution R for two neighboring peaks is
calculated as:
R = (t
i+1
- t
i
) / (w
0.607i
+ w
0.607(i+1)
)
