Soil Matrix CRMs

Soil matrix CRM is a kind of certified reference material and it is also a kind of physical reference material. In accordance with the relevant provisions, soil matrix CRMs are attached with certificates, which makes it traceable. As certified reference materials, soil matrix CRMs can be used to calibrate instruments, determine the accuracy of testing methods and others.

In addition, the soil matrix CRM combines the tested material with the matrix material, which is closer to the properties of the tested sample. Therefore, using soil matrix CRMs can reduce the influence of the matrix effect and thus improve the detection accuracy. Commonly used soil matrix CRMs include anions in soil CRM, clean clay loam, diesel, nutrients in soil matrix CRM and others.

Application Fields

Soil matrix CRMs are mainly used in various detection methods to analyze soil samples, including X-ray fluorescence spectrometer, inductive coupled plasma emission spectrometer, atomic absorption spectrophotometry and atomic fluorescence spectrometry.

Analysis soli sample by X-ray fluorescence spectrometer: The soil matrix CRMs can be used in X-ray fluorescence spectrometry for rapid and non-destructive measurement of soil samples. It is necessary to calibrate the instrument with soil matrix CRMs during the detection, and obtaining standard curve, which is the basis for subsequent qualitative and quantitative analysis. In addition, the results obtained are accurate because the soil matrix CRMs largely eliminate the matrix effects.
Analysis soli sample by inductive coupled plasma emission spectrometer: Inductive coupled plasma emission spectrometer has a very important application in the analysis of the types and contents of metal elements in soil samples. This method has the advantages of high sensitivity, low detection limit and high selectivity. Moreover, during inductive coupled plasma emission spectrometer testing, soil matrix CRMs are required to make standard curves, which are essential for quantitative analysis.
Others: In addition to the two fields mentioned above, the soil matrix CRMs have been widely used in soil sample analysis by atomic absorption spectrophotometry and atomic fluorescence spectrometry. In these test methods, soil matrix CRMs are used to calibrate the instrument and to make standard curves.
