185 - 910nm AAS Atomic Absorption Spectrophotometer For Metal Analysis

185-910nm AAS Machine Atomic Absorption Spectrophotomter for Metal Analysis

Introduction of Atomic Absorption Spectrophotometer
Atomic absorption spectrometry (AAS) detects elements in either liquid or solid samples through the application of characteristic wavelengths of electromagnetic radiation from a light source. Individual elements will absorb wavelengths differently, and these absorbances are measured against standards

Features of Atomic Absorption Spectrophotometer AA2300

1. Stability: Double-beam system can automatically compensate the light source drift and wavelength drift caused by the variation of temperature (with the function of the eliminating the affection of wavelength drift on the base line stability) and electronic circuit drift so as to reach a good basic line stability.
2. Flame instrument 8-level safety interlock: with a complete set of safety interlock systems, multiple pressure monitoring, automatic safety protection functions, acetylene leakage detection.
3. High energy optical path: A total reflection system is adopted to eliminate color difference in full range. By means of chemical conversion, a round light spot of the light source becomes a long light spot, which enters into the slit. Therefore the light flux of double beam is enhanced.
4. Atomizer: high-efficiency glass, all-plastic, stainless steel atomizer
5. Multi-functional analysis mode: for methods of flame absorption, flame emission, graphite furnace atomic absorption and hydride generation.


Applications of Atomic Absorption Spectrophotometer
Many elements, especially the emblematic elements, are essential nutrients for the growth and development of living organisms. However, some elements, especially heavy metals, can become toxins if absorbed in excess. Therefore, the atomic absorption spectrophotometer has been widely developed in the field of agriculture, and has now become a routine analytical technique and a national standard for the determination of certain elements in the analysis of soil, fruits and vegetables, food and feed.
