原子吸收光谱仪

作者:        发布于:2010-09-15

  型号:GBC AVANTA M

  生产厂家:澳大利亚GBC科学仪器公司

  主要技术指标:

    波长范围185~~900nm 、八灯自动转换到测试位置。

    超脉冲氘灯背景校正技术、校正值可达2.5ABS.

  基本原理:试样中待测元素的化合物,在高温中被解离成基态原子,基态原子吸收光源发出的特征谱线,在一定条件下,被吸收的程度与基态原子浓度成正比。即吸光度A=KC,由此可以确定样品中待测元素的浓度。

  仪器优点:灵敏度高,抗干扰能力强,测试数据准确,用样量少,是定量分析的国家标准分析方法。已广泛应用于工农业、生物医学、环境保护、商品检验等各行各业的元素定量分析。可以检测三十五种以上元素。

  

  Model  GBC AVANTA M

  Manufacturer:   GBC Scientific Equipment Pty Ltd.Australi

  Main Specifications:  1.Wavelength range: 185~~900nm.

               2.Background correction :

  Deuterium(D2) Lamp: 185~~425nm(approx). the correction is 2.5ABS.

  Atomic absorption spectrometry is based on the following Principle:

  A Compound of elements to be analyzed is atomized as ground state atoms at a high temperature.Under some certain conditions these atoms will absorb the characteristic spectrum lines of a coutimum source and the absorbed intensity is directly proportional to the density of ground state atoms.

  This instrument is well Equipment. It belongs to a conventional  quantitative analytical apparatus with a high sensitivity and rapid measuring speed as well as  anti-disturbance ability.It is extensively applied in biology,geology,material Sciences and business. More than thirty-five kinds of elements can be measured by it.
