Soils.ATR

Set of 25 designed soil samples, containing water and oil concentrations that are independently varied. This mixing scheme called “diagonal design” provides uncorrelated variability of both components and even coverage of the chosen concentration ranges (0%-13% for both components) using the minimum number of samples. The calibration samples were analyzed using a fiber optic ATR (attenuated total reflection) probe (art photonics GmbH, Germany) with an IRE made of zirconium dioxide connected to the Fourier transform IR spectrometer.
