Metrohm NIRS XDS Interactance OptiProbe Analyzer - Manual (Page 41)

▪▪▪▪▪▪▪ 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. The DCM will self-select as an OptiProbe Module.
Select the proper probe type, either Interactance Reflectance, or Interactance Immersion. The user
should enter a logical name for the DCM, such as that shown above.
Use the default of 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.
