Scope

Scope: This document specifies the principles, detection methods, and requirements for determining the elemental compositions of titanium (Ti), vanadium (V), chromium (Cr), manganese (Mn), nickel (Ni), copper (Cu), niobium (Nb), tungsten (W), and molybdenum (Mo) in low-alloy steel and stainless steel materials in chemical plants using handheld X-ray fluorescence spectrometers for on-site analysis. This document is applicable to the on-site material verification of titanium (Ti), vanadium (V), chromium (Cr), manganese (Mn), nickel (Ni), copper (Cu), niobium (Nb), tungsten (W), and molybdenum (Mo) in low-alloy steel and stainless steel materials in chemical plants using handheld X-ray fluorescence spectrometers. Main technical content: Measure the X-ray intensity and calculate the preliminary content of metal elements in the sample according to the calibration curve. Finally, by testing similar certified standard materials/standard samples, the measurement results are corrected based on the deviation between the certified value and the measured value of the elements in the certified standard samples/standard materials. The specific detection method follows the semi-quantitative analysis method in GB/T 16597.
