(Summary description)　　The micro chemical atomizer is a new type of hydrogenation generation or cold atomic absorption device, and is one of the products of the utility model patented micro multifunctional sampling device. 　　This device is suitable for all flame atomic absorption spectrometers. In order to meet the requirements of different AA instrument software, the device is designed with an automatic control system, which can complete a measurement within 10-30 seconds only by pressing the mouse twice. Miniature chemical atomizers are currently used to determine Pb, Cd, Hg, As, Bi, Sb, Se and Sn. 　　In addition to high sensitivity, fast speed, no background, low cost, compared with other hydride generators or atomic fluorescence, the main features of this device are: 　　1. Overcome the difficulty in the determination of Pb and Sn by the hydrogenation method. Pb and Sn in actual samples can be determined in 4% HCl medium; 　　2. Established a new method for the determination of Cd in 4% HCl by cold absorption method; 　　3. The system has no memory effect, and usually only needs to be measured once. It is especially important for the determination of Hg; 　　4. It can be used for the determination of As, Pb, Cd, Hg in samples with high salt (such as 10% NaCl) and high sugar (such as concentrated fruit juice or syrup containing 70% sugar).
