Metrohm NIRS XDS RapidContent Analyzer - Manual (Page 39)

A Data Collection Method (DCM) must be established
to communicate with the instrument.
There are no Data Collection Methods available upon
initial connection. Click on “New”.
The instrument “self-identifies” as an XDS system. Depending upon the configuration, the DCM will
self-select as either a Rapid Solid Module or a Rapid Content Module, with or without spot size
adjustment. Select the proper module for your type of system. The user should enter a logical name
for the DCM.
Use 32 scans for “Sample” and 32 scans for “Reference.” The instrument scans on each forward
swing and each backward swing of the grating, unlike previous Metrohm instruments. Thus, 32 scans
are accomplished on only 16 grating cycles, and are very rapid. Click “OK” when finished.
The user will hear a slight ticking sound from the internal order sorter whenever the lamp is on. This
is normal, and has no effect on component life. The parts are kept in motion to reduce “wait time”
before instrument stabilization.
