加标回收率的测定是国内外化学实验室经常使用的一种质量控制技术,已广泛应用于各种分析方法,如容量分析法、分光光度法(紫外-可见分光光度法、原子吸收分光光度法、电感耦合等离子光谱法)、色谱分析法(气相色谱法、液相色谱法)、质谱分析法等。而目前在国内还没有将加标回收率用在重量分析法的质量控制中。然而,在参加国际AIHA Proficiency Analytical Testing Programs(PT)的过程中发现,英国健康和安全
Spike recovery is a kind of quality control technology often used in chemical laboratories at home and abroad. It has been widely used in various analytical methods such as volumetric analysis, spectrophotometry (UV-visible spectrophotometry, atomic absorption spectrophotometry Method, inductively coupled plasma spectrometry), chromatographic analysis (gas chromatography, liquid chromatography), mass spectrometry and the like. At present, the spike recovery has not been used in the gravimetric method of quality control in China. However, participating in the International AIHA Proficiency Analytical Testing Programs (PT) found that UK Health and Safety
