Spike Channel
Another feature of PeakSimple for
Windows allows you to display the reo
suits of a matrix Spike Channel sub–
traction. The example shown below
demonstrates the peak area counts of
a unspiked channel being subtracted
from the area counts of a spiked chan–
nel.

After selecting channel 2 as the Spike Channel, the area counts for channel 2are
subtracted fromchannel 1 to equal
697, (939 -
242
=
697).
Thedifferenceof
697
indi–
cates the area counts of the amount of sample spiked into channel 1.
