IR spectroscopy detects that oxygen defects act as active centres

oxygen defects act as active centres

In the chemical industry, heterogeneous catalysis is vital for the manufacture of basic or fine chemicals, in catalytic converters of exhaust gas and for the chemical storage of solar energy. A new infrared spectroscopy method can study processes at surfaces of oxides used as catalysts.
In the chemical industry, heterogeneous catalysis is vital for the manufacture of basic or fine chemicals, in catalytic converters of exhaust gas and for the chemical storage of solar energy. Scientists from the Karlsruhe Institute of Technology (KIT) and Ruhr-Universität Bochum (RUB) in Germany have developed a new infrared spectroscopy method in order to study processes at surfaces of oxides used as catalysts; their results have been published in Angewandte Chemie (doi: 10.1002/ange.201200585).

High-Throughput qNMR

It is well known that NMR is a very convenient technique for quantification, provided the amount of the material is within the limits of detection in NMR. 

When it comes to the actual calculations, this is a very straightforward process that does not require any fancy mathematics. Typically you will select the most convenient signal(s) or multiplet(s) in your spectrum and calculate the integral which can then be mapped to the corresponding concentration units by using a scaling factor that was previously calculated using some internal or external references.
