微波制样技术的应用近年来发展甚快,特别是用微波-酸消化试样原子光谱测定各种微量元素的方法已日趋普及,使用者且多.采用FR-1型全聚四氯乙烯密封增压微波消化罐(国家专利93239178·8),配以市售家用微波炉,一次投入费用低(5～7千元)而又能达到数万美元的进口设备的同样效果.经本刊1995年第1期第56页和1996年第1期介绍了FR-1型微波消化罐的性能及消化效果后,用户已遍及全国各省市,已为广大原子光谱分析人员所熟悉.采用FR-1型消化罐微波消解各种试样以其速度快(一般是3～5min)、试剂用量少(3～5ml)、污染少、空白值低、检出限低以及测定精度高等特点,深受用户好评.
Microwave sample preparation technology has developed rapidly in recent years, especially with microwave - acid digestion sample atomic spectrometry of trace elements has become increasingly popular, users and more. The use of FR-1 type polytetrafluoroethylene seal Pressurized microwave digestion tank (national patent 93239178.8), together with the market of domestic microwave oven, a low input costs (5 ~ 7 thousand) and can reach tens of thousands of dollars of imported equipment, the same effect. No. 1, No. 56 and No. 1, 1996, introduced the performance and digestion effect of FR-1 microwave digestion tank, and users are familiar with the atomic spectrometry analysts in all provinces and cities all over the country. Digestion tank microwave digestion of various samples with its fast (usually 3 ~ 5min), less reagent (3 ~ 5ml), less pollution, low blank value, low detection limit and high accuracy, by the user Praise.
