A statistical study on elemental analysis for 5 small organic compounds at 18 independent service providers across multiple countries demonstrates variation in the returned results that is outside journal guidelines (0.4%) in greater than 10% of measurements. The results indicate that a deviation of 0.4% is not a realistic journal requirement with the variability attributed to random error.

一项评估元素分析的国际研究

一项在多个国家/地区的 18 家独立服务提供商对 5 种小型有机化合物进行元素分析的统计研究表明，在超过 10% 的测量结果中，返回结果的差异超出期刊指南 (0.4%)。结果表明，0.4% 的偏差并不是一个现实的期刊要求，而可变性归因于随机误差。
