近年来我们先后购置了北京分析仪器厂的QGD-07型、广东佛山分析仪器厂的FQ型、SH型,1982年又引入日本ASSA-1610型红外线气体分析仪。运用这些仪器开展了棉花光合性能的研究,结果证明这类分析仪具有:(1)选择性能高,只对待测组份浓度变,化有反应。并对有重叠吸收波长的干扰组份易于滤掉。(2)灵敏度高,能分析到ppm级浓度。(3)反应速度快,测定一数值只需儿
In recent years, we have successively purchased the QGD-07 type of Beijing Analytical Instrument Factory, the FQ type and the SH type of Foshan Instrument Factory of Guangdong Province and the Japanese ASSA-1610 type of infrared gas analyzer in 1982. The use of these instruments to carry out the study of photosynthetic properties of cotton, the results prove that such analyzers have: (1) high selectivity, only the concentration of the tested components change, the reaction. And interfere with the wavelength of the overlapping components easily filtered out. (2) high sensitivity, can be analyzed to ppm level concentration. (3) reaction speed, a value of only children
