目的：实现普通分光光度计分析过程的自动化。方法：用微机化多功能离子分析器与分光光度计联机测定维生素C的含量。结果：以本法测定药物中维生素C含量，与1995年版《中国药典》记载的方法比较，结果基本一致。结论：采用本法比用普通分光光度法更加简便、快速，可广泛用于药物分析。
Purpose: To automate the analysis of common spectrophotometers. Methods: The content of vitamin C was determined on-line using a computerized multi-functional ion analyzer and spectrophotometer. RESULTS: The determination of vitamin C content in the drug by this method was basically the same as that recorded in the 1995 edition of the Chinese Pharmacopoeia. Conclusion: This method is simpler and faster than ordinary spectrophotometry and can be widely used for drug analysis.
