NIRCal chemometric software
NIRCal is a modern chemometric software package for use with Buchi FT-NIR Spectrometers. It can
be used for qualitative and quantitative applications. For method development a lot of comprehensive
pretreatments are available. However, the software is easy to use even for novices. The Calibration
Wizard guarantees the development of reproducible calibrations. Complex calibrations and interpreta-
tions are greatly simplified by the use of wizards, which automate standard procedures and help to
develop calibrations.

Measuring cells with their add-ons and accessories
The modulated light coming from the interferometer interacts with the sample. The light is then
detected in the measuring cell and the data is sent to the basic instrument.
The measuring cell has its own power supply and is galvanically isolated from the basic instrument. It
can be swapped without switching off the basic instrument and is automatically identified (plug & play).

Operating panel of a measuring cell
The START button is used to start a measurement without using a PC keyboard.
The STOP button is used to stop a measurement without using a PC keyboard.
An LED informs the user about the current instrument state:
Red
: Instrument is in error state
Green
: Instrument is ready to use
Green flashing
: Instrument is busy measuring
Yellow
: Power is on but the instrument is not yet initialized by the NIRWare software
For a description of the LEDs at the handle of the fiber optic, see sections 4.6.15 and 4.6.17.
