Спектралният анализ в близката инфрачервена област — недеструктивен и бърз метод за определяне на органичния въглерод в почвата

open access: yesПочвознание, агрохимия и екология, 2011
The basic principle for the soil organic carbon determination is based on the chemical destruction of soil organic matter or via heat at elevated temperature. These methods аrе time consuming, labour intensive and raise the cost of analysis.

Reflectance IR Spectroscopy

open access: yes, 2012
Infrared spectroscopy is study of the interaction of radiation with molecular vibrations which can be used for a wide range of sample types either in bulk or in microscopic amounts over a wide range of temperatures and physical states. As was discussed in the previous chapters, an infrared spectrum is commonly obtained by passing infrared radiation ...
