基于光谱原理的物质成份分析仪器分为红外光、可见光、紫外光三种。其中红外光分析器应用很广,而紫外光分析器只是在近年来才得到发展。目前紫外光分析器定为商品型生产的极少。但是从文献报导看来,它的发展前途很大。许多有机物在红外区域内没有明显的吸收作用,它们的吸收峰值落在紫外区域。另外紫外光分析器较之红外光分析器具有更高的灵敏度和稳定性,可用来分析含量很少的物质成份,但它比红外分析器有较差的选择性。
Based on the principle of spectroscopy material composition analysis instrument is divided into infrared light, visible light, three kinds of ultraviolet light. Among them the infrared light analyzer is widely used, but the ultraviolet light analyzer is only developed in recent years. At present, the UV analyzer is set to produce very few products. However, it seems from the literature that its development has a bright future. Many organic matter has no significant absorption in the infrared region and their absorption peak falls in the ultraviolet region. In addition UV analyzer than the infrared light analyzer has a higher sensitivity and stability, can be used to analyze the content of less material components, but it is less than the infrared analyzer selectivity.
