X ray fluorescence spectrum analyzer and other analytical instruments, such as: AAS, ICP and so on, what are the advantages and disadvantages?
Both ICP and AAS instruments are tested by chemical methods. The advantages are: high accuracy and good repeatability. Generally speaking, third parties are using this method. The disadvantages are low test efficiency, great pollution and high test cost
The individual test experience, reference: X ray fluorescence spectrum analyzer (XRF) and ICP AAS, the former is similar to the test principle, using physical methods, with the surface electron atom binding energy reaction surface chemical composition; they are using chemical methods, qualitative and quantitative analysis were carried out using spectral wavelength and intensity of different elements; XRF test low cost, simple operation, no damage to the sample, comparing the test for homogeneous material or surface coating products, data stability and accuracy than ICP and AAS.
More samples, it is recommended to buy 1 sets of XRF and 1 units of ICP, XRF screening of samples for preliminary screening, there is a problem with ICP for accurate quantitative. Many large laboratories are doing so
