Soil analysis
Bruker offers both FTIR and FT-NIR spectrometers widely used for soil analysis applications. The output of the MIR and NIR analysis is a complex spectrum, that includes information on important parameters. Our OPUS software with automatic optimization of calibration models can then use the measured reference spectra of known concentrations to create the most accurate models for determining these parameters.
Both NIR and MIR have advantages and disadvantages. NIR allows measurement of larger sample volumes and is less demanding in terms of sample preparation. While MIR requires grinding to fine particles, it often achieves more accurate calibrations and is useful for a greater number of parameters.
Example of monitored parameters:
- Organic C
- Inorganic C
- Total carbon
- Total nitrogen
- Nitrates
- Potassium, Aluminium, Calcium ...
- Organic component,
- Clay share
- Sand fraction
- pH
- etc.
For soil analyzes, we offer both the compact ALPHA II FTIR spectrometer and the higher INVENIO spectrometer range, which can be expanded with an autosmapler for larger samples and possibly with a photoacoustic measuring cell (PAS), which is also used in soil applications
