Total value for the column is the sum of

concentrations for all components.

concentration% Normalization of concentrations for all

peaks using the NORM value entered in

the Total % for normalization field (default

setting 100%):

% = NORM • W

) / ää

)

Total value for the column equals NORM

for the main table, and the sum of concen-

trations in the group for the group table.

rel. concentration Relative concentration of the component

relative to the standard component, as-

sumes concentration of one of the compo-

nents to be known in advance. The con-

centration of the component is calculated

by the formula:

= W

) / V' = W

) • C

/ W

where V' = W

) / C

is the effective

(reduced) volume of injected sample. The

standard component concentration C

entered by the user.

Total value for relative concentration col-

umn does not include the concentration of

the standard component.

rel. concentration% Relative concentration percent differs from

concentration% by exclusion of standard

component(s) from summation, so that

sum of all concentrations (excluding stan-

dard) equals NORM.

Total value for the column equals NORM

value for main peak table, and the sum of

concentrations in the group for Group ta-

ble.

index Linear or logarithmic retention index for

identified components.

Total value for the column is a weighted in-

dex average with absolute concentration as

weight.
