Report elements

If

Quantification method = Custom

has been selected, the peak ta-

ble can be customized on the user's choice. After clicking the

<Customize>

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).

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

- t

) / 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)

)

where i and i+1 indexes refer to the neigh-

boring peaks, and w

0.607

stands for the

peak width at 60.7 % of the peak height.
