Optima 4300DV型全谱直读电感耦合等离子发射光谱仪

作者:        发布于:2010-09-11

  

  型号: Optima 4300DV

  生产国别厂家美国 PerkinElmer公司

  主要技术指标:

    波长范围:165nm-782nm

    光谱分辨率:0.006nm200nm处)

  基本原理:

   将样品溶液以气溶胶形式导入离子体炬火焰中,样品被蒸发和激发,发射出所含元素的特征波长的光。根据元素浓度与谱线强度的关系,对样品中相应元素进行定性定量分析,该仪器主要用于液体试样(包括经化学处理能转变成溶液的固体试样)中金属元素和部分非金属元素的定量分析,具有检出限低、稳定性好,同时多元素分析,分辨率高,垂直和水平双观测等特点。

  该仪器具有以下特点:

    1 测量元素的范围:除HFCl、惰性元素外的七十多种元素。对难熔样品中元素及稀土元素的测定是其一大特长。

    2 测定含量范围:从常量(一般小于10%)到痕量(10-4%

  主要用途:

    广泛应用于冶金、地质、环境、半导体、材料等领域中各种常量、微量元属的定性、定量分析。

  

  Model: Optima 4300DV

  Manufacturer: Perkin Elmer Ltd., USA

  Main specifications:

  Wavelength range: 165~782nm

  Resolution: 0.006nm (at 200nm)

  A sample solution is instructed into an inductively coupled plasma torch as gas sol form, the sample is evaporated and stimulated, which emitts characteristic wavelengthes of elements contained in the sample. By the relationship between the concentration of elements and intensity of spectrum, it is mainly used to make qualitative or quantitative analysis for metal elements and nonmetal elements in liquid samples (include solid sample which can be turned into solution by chemical treatment) . The instrument has following characteristics: low detectable limit, fine stability ,exceptional speed (ability to measure any element in any order. many elements at a time), excellent resolution, high sensitivity, dual viewing in vertical and level ways.

  The instrument has other characteristics as following:

  (1) Element measuring scope: more than seventy kinds of elements can be measured, including elements of difficultly melted sample and rare earths except Hydrogen, Fluorine ,Chlorine and inert elements.

  (2) Element's content identification scope:

    for normal: <10 %

    for trace: >10-4 %

  The instrument is widely applied in the fields of metallurgy, geology, environment, semiconductor, material, etc., for normal and minimal elemental analysis, qualitatively or quantitatively.
