Harmonization of spectrometers to assure that shared spectra are relevant is an important consideration.
I have 30 spectra of soils of Ecuador, cultivated with cocoa and 25 spectra of cocoa leaves
Use Infrared for transformation of Fourier (FTIR) and the program ORIGIN PRO for the graphis, use as a reference of the functional groups
Take the soil and the leaves of cocoa make the pill and infrared now I have 100 soil samples taken at different depths of a basin
I want to do FTIR but I do not have the spectral database
The new "Identify" feature of optical spectroscopy software http://Spectragryph.com allows to create custom spectral databases from all kind of spectral file formats and measurement techniques. Then, you can also search and match unknown sample spectra against the established spectral libraries.
Hello Dan,
We are using ASD FieldSpec for acquiring the spectral data with a specific protocol. for more info, see:
