Data compression

IC NET / Process / More / Compress

Selection of this menu item opens the

Raw data compression

win-

dow for compression of the raw data of the active chromatogram

by summing up several neighboring points.

Divisor

Coefficient of compression (the number of

data points is reduced by this value). The

default value of the compression coefficient

is calculated so that the width at half-height

of the narrowest peak will be digitized by at

least 30 points. If the user enters a coeffi-

cient of compression that exceeds the

value offered by the software, integration

precision may decrease.

8.6.5

Invert chromatogram

IC NET / Process / More / Invert!

This menu item inverts the response curves for all channels of the

chromatogram so that negative peaks become positive and vice

versa (useful for chromatograms with wrong input polarity).
