紫外、可见、近红外区的分光光度法,利用物质分子与离子光谱对物质作定量和定性分析,由于其方法适应面广、方法稳定、灵敏度适中、操作简便、设备价格便宜等多方面原因,使这一波段的分光光度计成为长盛不衰的分析仪器,其销售量及普及程度一直列在分析仪器商品前八名内,世界上的分析工作量有20～30%是用分光光度计完成的,在我国科研和生产中更显其主要地位。从85～96年间,国内市场销售量稳定在1.5～2万台之间;国际市场销售量也在1～1.5万台之间。其在质控、环保、农业、化工、医疗卫生、食品、轻工、
UV, visible, near infrared spectrophotometry, the use of material molecules and ion spectra of substances for quantitative and qualitative analysis, due to its wide range of methods to adapt, the method is stable, moderate sensitivity, easy to operate, cheap equipment and many other reasons, Make this band of spectrophotometer into a long-standing analytical instruments, its sales and popularity has been listed in the first eight in the analytical instruments, the world’s analytical workload of 20 to 30% is the use of spectrophotometer Completed, in our country more prominent research and production. From 85 to 96 years, sales in the domestic market remained stable at between 1.5 and 20,000 units; the sales in the international market also ranged from 1 to 15,000 units. Its quality control, environmental protection, agriculture, chemicals, health care, food, light industry,
