HAPSITE ER Operating Manual
The results screen includes:
Retention time window . . . . . . . . . AMDIS uses a decimal time format. Multiply
the numbers after the decimal point to
convert to a seconds format.
Identifications window. . . . . . . . . . Lists the identifications in order of retention
time. If a question mark is displayed before
the identification, the match is between
70-79. If two question marks are displayed,
the fit is between 60-69, and if three question
marks are displayed, the fit is less than 60.
Component window . . . . . . . . . . . . Displays the width of the peak in terms of
scans, the purity of the peak and the min.
abund (minimum abundance). This is the
abundance of the smallest observable mass
spectral peak and model, which is the m/z
value or TIC used to determine the peak
shape. It is generally the ion that rises and
falls the fastest.
Match window. . . . . . . . . . . . . . . . . Displays the quality of the spectral match. If
the Net is greater than 70, the identification is
considered to be a good match. If the Net is
greater than 80, the identification is
considered to be a very good match. If the
Net is greater than 90, the identification is
considered to be an excellent match.
Library Tab . . . . . . . . . . . . . . . . . . . Displays the search library, CAS number,
synonyms and formula for the compound that
is highlighted in the identifications box.
Analyze Button . . . . . . . . . . . . . . . . Sets the library pathway, which may be
necessary when reloading the ER IQ
program. See section 8.5.1, Setting the
AMDIS Pathway, on page 8-18.
Help . . . . . . . . . . . . . . . . . . . . . . . . . Detailed Help instructions about AMDIS.
Done . . . . . . . . . . . . . . . . . . . . . . . . Closes the AMDIS screen.
Confirm . . . . . . . . . . . . . . . . . . . . . . Labels the peaks in the chromatogram that
were not identified by AMDIS and allows the
peaks to be exported to NIST for further
identification. See section 8.5.3, Confirm
Screen in AMDIS, on page 8-22 for further
information.
Print . . . . . . . . . . . . . . . . . . . . . . . . . Prints the AMDIS data in a report format.
