In X ray fluorescence spectroscopy,the oxide borate fusion sample preparation technique for the complete elimination of the mineral effect and the effect of sample size,the sample is diluted and flux can reduce the matrix effect of coexisting elements caused by a certain degree,and is considered to be the most accurate method for sample preparation of X in X-ray fluorescence analysis.

The fusion sample is a special instrument and equipment for melting sample preparation.It is a special laboratory preparation equipment for X ray fluorescence instrument.
