Analyses of standard reference materials, if recognised by GLITTER, will be marked
with an asterisk in the table. If a standard analysis is not recognised by GLITTER,
click on the row label that contains that analysis to activate it as a standard (another
click on the row will de-activate it). The standard reference material used appears in
the first (upper) droplist in the window and can be changed if required by making
another selection in the droplist.
The use of up to three isotopes as internal standards (IS) is allowed. The number of
internal standards to be used is selected from the second (lower) droplist in the
“Standards” window, and the identities of the internal standards are selected from
the minor droplists below it. The selected IS isotopes appear as column headings in
the table, and the IS values for the standard analyses (e.g. NIST 610) ALWAYS
appear in the first column. Other values should be entered in the appropriate column
(see section 5.2 for more details).
For some ICP-MS instruments, the dwelltime is not written to the datafile and it
must be entered manually by the user in the text box that appears in the “Standards”
window. Enter the dwelltime in units of milli-seconds (ms), and press “Enter”, or
select “Multiple dwells” if necessary and proceed to the dwelltimes popup window.
Typing the IS values in the table provided is, unfortunately, a little tedious at this
stage (an IDL and Microsoft Windows problem). To activate a cell, select the cell,
press “Enter”, type the value and press “Enter” again. Move to the next cell by using
the arrow keys or the mouse, and repeat the process. Once all the values have been
entered (excluding the values for the standards - GLITTER enters these
automatically), click the “Accept” button. The “Standards” window disappears, the
results are calculated and the data appear in the results table.
Click any of the “Save Settings”/ “Save” buttons (in the “GLITTER”, “Review” or
“Standards” windows) to write the values of the internal standard(s) and the current
marker settings to a file with the same name as the datafile, but with the extension
.gli (Step 8 below).
