This experiment uses Fourier transform infrared spectroscopy (FTIR) to analyze organic compounds. The CIFOR-ICRAF Soil and Land Health Laboratory is a leading global lab that offers robust, cost-efficient and rapid analysis of soil, plants and agricultural inputs such as manure and fertilizers using dry spectral methods. For a given type of nucleus, high-resolution spectroscopy distinguishes and counts atoms in different locations in the Mass Spec Fundamentals Seminars by Stanford University Mass Spectrometry; UC Davis Proteomics Online 2d Short Course; Suggested by Frederik Lermyte @FLermyte.
