XDS MultiVial Module
The XDS MultiVial Analyzer is primarily designed for vial sampling, which is the focus of this manual.
Optional sampling devices are available, and are also described following the vial information. For
optional sampling accessories, please contact your Metrohm NIRSystems distributor.
5.1 Introduction to Vial Analysis
The MultiVial Analyzer is designed to provide
sampling for trays of vials, like that shown at
right. This provides for a greater degree of
automation, and permits the operator to
perform sample loading and other duties while
one rack is being scanned by the instrument.
This extends the usefulness of the instrument
into a routine analytical tool, since no operator
input is required, once the sample information
is entered and the rack is in place. Spectral
information for each vial is acquired and
stored, and the calibration or library
identification is automatically applied.
Partial racks may be run, and the order of scanning determined by the user. Vision provides easy
graphical tools to make setup easy and accurate. No special software skill is required to set up the
instrument for routine analysis, once the calibration is in place.
Because the MultiVial may be used with different size vials, Vision accommodates setup by offering a
screen to help define the tray dimensions, including vial spacing. The number of columns and rows of
vials is entered, along with the manufacturer’s nominal diameter and tolerance. Vision takes this
information and provides centerline data for each bored hole in the tray, which can be used for
machining.
There are four default vial sizes set up in Vision, for commonly-used vials. The 15mm vial diameter is
shown as an example:
The setup screen for sampling is straightforward and easy to use. An example is shown:
