Automatic dosages took place a short time ago in oenology laboratories. First researchs about automation of usual manual analysis have been completed by I.N.R.A. Station of Dijon during 1969--1972 years. Then, other researchs were made and in 1974 the first automatic analyser appeared in application laboratories. In all cases continuous flow method was used. First dosages which has been carried out are volatic acidity, residual sugars, total SO2. The rate of work is 30 samples an hour. Then, an original way for free SO2 was suggested. At present, about a dozen of laboratories in France use these dosages. The ethanol dosage automation, very important in oenology, is very difficult to carry out. A new method using a thermometric analyzer is tested. Research about many dosages as tartaric, malic, lactic acids, glucose, fructose, glycérol, have been performed especially by I.N.R.A. Station in Narbonne. But these dosages are not current and at present no laboratory apply them. Now, equipments price and redemption, change of tradionnal dosages for automatical methods and the level of knowledge required for operators are well known. The reproducibility and the accuracy of the continuous flow automatic dosages allow, for enough important laboratories, to make an increasing number of analysis necessary for wine quality control.
自动定量分析不久前在酿酒学实验室中开始应用。法国国家农业研究院第戎研究站在1969年至1972年期间完成了关于常规手工分析自动化的初步研究。随后，又开展了其他研究，并于1974年第一台自动分析仪出现在应用实验室中。在所有情况下均采用连续流动法。最初进行的定量分析项目有挥发酸、残糖、总二氧化硫。工作效率为每小时30个样品。随后，提出了一种测定游离二氧化硫的新方法。目前，法国约有十几家实验室采用这些定量分析方法。乙醇定量分析的自动化在酿酒学中非常重要，但实施起来非常困难。一种使用温度分析仪的新方法正在进行测试。特别是法国国家农业研究院纳博讷研究站开展了关于酒石酸、苹果酸、乳酸、葡萄糖、果糖、甘油等多种成分定量分析的研究。但这些定量分析方法尚未普及，目前没有实验室应用它们。现在，设备价格与赎回、传统定量分析方法向自动方法的转变以及操作人员所需的知识水平都是已知的。连续流动自动定量分析的重现性和准确性使得足够多的重要实验室能够进行越来越多的葡萄酒质量控制所需的分析。
