Development and Application of Series Re-calibration Samples of Copper and Copper Alloy
In accordance with the requirements of the reference materials technical specifications,refer to some countries existing standards of chemical composition of copper and copper products,design the chemical composition of each re-calibration samples.Using proper methods of batching,smelting technique and extrusion processes etc.,developed a set of re-calibration samples of copper and copper alloy.These samples are mainly used for standardization of photoelectric direct reading spectrometer instrument,to meet the re-calibration of various elements of Cu,Pb,Fe,Ni,Bi,Sb,P,As,Al,Zn,Mn,Si,Sn,Cr,Cd,Zr,Mg,S,C,Ag,Co,Se,Te in the copper,brass,bronze,copper-nickel and other copper alloy.Determine the content of the various elements using a variety of methods,these samples can also act as control samples for the control analysis of the relevant elements separately.In comparison with existing international re-calibration samples,the series of samples have advantages of small quantity,wide coverage,more reasonable distribution of elements.
