本文介绍的荧光分光光度计,其工作波长范围为360—650毫微米,波长准确度为360—600±1毫微米,半波宽度580毫微米处为8毫微米,最灵敏挡的灵敏度可检测0.05 ppb的荧光素钠溶液,高压电源稳定度优于0.1％,测试精度约为±1.5％。荧光分析法具有如下特点:(1) 灵敏度高,可检测出含量低至0.05 ppb的强荧光性物质;(2) 测量的线性范围宽,其上下限浓度差别达一千倍左右;(3) 取样量少,一般取样量是几微升至几毫升;(4) 测定速度快,每个样品的测定仅需几分钟。荧光分析已广泛应用于工业、农业、冶金、生化、医药等部门。它在环保中的应用也相当广泛,例如:强致癌 This article describes the fluorescence spectrophotometer, which operates in the wavelength range of 360-650 nm, the wavelength accuracy of 360-600 ± 1 nm, 580 nm half-width width of 8 nm, the most sensitive block sensitivity can be detected 0.05 ppb sodium fluorescein solution, high voltage power supply stability is better than 0.1%, the test accuracy of about ± 1.5%. Fluorescence analysis has the following characteristics: (1) high sensitivity, can detect as low as 0.05 ppb fluorescent substance; (2) the linear range of measurement, the upper and lower concentration difference of about a thousand times; (3) Sampling less, the general sampling volume is a few microliters to a few milliliters; (4) Determination of speed, the determination of each sample only a few minutes. Fluorescence analysis has been widely used in industry, agriculture, metallurgy, biochemistry, medicine and other departments. It is also widely used in environmental protection, for example: strong carcinogenic
