Rapid Determination of Carbon and Sulfur in Farmland Soil Samples by High Frequency-Infrared Carbon-Sulfur Analyzer

  • A method for rapid determination of carbon and sulfur in farmland soil samples by high frequencyinfrared absorption spectrometry was reported in this paper. The analytical conditions such as sample amount, flux added, oxygen flow rate, etc. have been tested and optimized. The accuracy and precision of the method were tested and accuracy of RE<10%, precision of <2% RSD for total carbon (n=8) and <9% RSD for sulfur (n= 8) were obtained. The method solves the problems such as matrix effect and low electromagnetic response in the determination of carbon and sulfur in soil samples. The method has been applied to the determination of carbon and sulfur in farmland soil samples with satisfactory results.
