Sensitivity . . . . . . . . . . . . . . . . . . . 1-30, used in model peak perception ranges:
30, 15, 10, 3, 1. As the value for this
parameter increases, increasingly noisy and
broad peaks are sought at the expense of
analysis time and increased risk of false
positives. An increase in the sensitivity will
extract broader peaks, resulting in an
increase in the extraction of smaller and
noisier peaks.
Resolution. . . . . . . . . . . . . . . . . . . . High/Medium/Low, Default Medium: As the
level of resolution goes up, the program
separates peaks that are closer together.
If Analyze Region is selected, see Figure 11-31 , the AMDIS is directed to only
search in the scan range selected. This is for specialized use, and does not need
to be utilized for normal usage. The default of Analyze Region off (i.e., unchecked)
will search the entire range specified by Low Mass and High Mass.
Figure 11-31 Analyze Region
When setting up the AMDIS library for qualitative analysis the HAPSITE.msl is the
default library for the system. See
Figure 11-32 .
Figure 11-32 The Libraries
To view other library choices, select the Browse button, refer to Figure 11-32 . There
are several small and specific libraries in addition to the HAPSITE.MSL See Figure
11-33 . Many of the compounds found in these small libraries, that can be detected
by the HAPSITE, are incorporated in the HAPSITE.MSL file.
NOTE: INFICON recommends using HAPSITE.MSL.
