Analysis of urinary calculi by X-ray diffraction: The evaluation of X-ray diffraction for the analysis of urinary calculi led to the substitution of the analysis by qualitative-chemical reactions. This instrumental method is performed in the routine laboratory in Zurich since two years. The interlaboratory quality assurance programme of 100 laboratories showed the advantage of the new method, producing correct results. On the contrary the old fashioned method by qualitative-chemical reactions yields questionable results.
通过X射线衍射分析尿结石：对用于分析尿结石的X射线衍射的评估导致了用定性化学反应分析的替代。这种仪器方法在苏黎世的常规实验室中已经开展两年了。100个实验室的实验室间质量保证计划显示了这种新方法的优势，能得出正确结果。相反，用定性化学反应的老式方法得出的结果存疑。
