6.2.3 Additional Vial Dialog Functions
There are several other important functions to be set or used in the Vial Dialog box. They are shown
below, and described in the text that follows.
Starting at the right side:
Samples per Reference:
This setting defines the number of sample spectra to be taken per reference scan. With multiple
samples, it is cumbersome to take a reference scan for each sample spectrum, and very time-
consuming. Because it is not necessary to take a reference spectrum for every sample scan, Vision
may use the same reference scan for a number of sample spectra.
The default is “10”, as shown above. This means that on a tray of 20 vials, Vision will take an initial
reference scan, then scan the first ten vials. Then Vision will take another reference scan, and go on
to scan the last 20 vials. If the tray has fewer than 10 vials, Vision will scan up to ten vials, if the
setting is “10”. If the setting is another number (other than 10) Vision will use that setting as the
maximum number of vials to be scanned per reference.
A “0” may be entered in this field, and Vision will scan the whole tray with a single reference scan.
Repeat:
A given tray may be scanned multiple times, to acquire “replicate” data. This is not often done,
though some users may want two or more replicates of the data for statistical reasons.
As a rule, this should be left at “1” unless there is a specific reason that replicates are required.
Paste:
As explained in the previous section, if the Sample ID names exist in an Excel spreadsheet, they may
be pasted directly into the table. The “Paste” button is used to place the Sample ID names into the
