Loading Samples for CPM/Xtal CPM
An example loading sequence for a cpm program using blanks and replicates is shown in
Figure 5.2.
When loading samples for cpm, if blanks or replicates are not used, the samples may be
loaded in any manner desired. If blanks are specified in the User Program as described in ID
Section 4, the blanks must be loaded first. Any number of blanks may be used. After the
blanks, an empty space is used, signal-ling the instrument that samples follow. Load the
samples after the empty space.
