This article details a comprehensive three-pronged strategy to eliminate higher-order diffraction interference in X-ray single-crystal analysis. The methods involve hardware filtration at the source using monochromators and slits, parameter optimization during data collection to suppress detection, and software correction algorithms for residual effects in data processing. This combined approach ensures high-precision crystal structure determination by controlling intensity errors.
