Product Description


AA2250 Atomic Absorption Spectrophotometer AAS Spectrometer for Trace Metal Analysis

Product Introduction

AAS (Atomic Absorption Spectrophotometer), analyzes metal elements based on the effect of atomic vapor in the ground state of the substance on the absorption of characteristic radiation. It can sensitively and reliably determine trace or trace elements. The AAS is mainly composed of 4 parts: light source, atomizer, spectroscopic system, and detection system. This type of instrument has the advantages of simple structure, low cost, high sensitivity, etc.

Product Features

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. Full-reflection dual-beam optical path, high optical path stability

3. High precision of measurement: Gas path system is equipped with precision pressure stabilizing and current stabilizing devices to reach stable flame and low noise. Specially designed fine light beam passes through the flame to ensure a high precision analytical test and low characteristic concentration.

4. 6 lamp holders preheat simultaneously to improve detection efficiency

Product Application

Metal analysis of mining and geology, mining and geology, mining and geology, pharmaceuticals, foods and beverages, oil and petroleum, agriculture, forensics.






System Configuration

Flame Atomic Absorption Spectrophotometer
Suitable for the analysis of low and medium temperature elements, atomization temperature at room temperature ~2200℃. The content of elements to be measured in the sample is generally analyzed in the ppm level (e.g. K, Ca, Na, Mg, Cu, Zn, Pb, Cd, Ni, Cr, Fe, Mn, Li, In, pb, pd...)




Graphite Furnace Atomic Absorption Spectrophotometer
Suitable for the analysis of low and medium temperature elements, atomization temperature at room temperature ~ 3000°C. The content of elements to be measured in the sample is analyzed in the ppb level (e.g. Cu, Pb, Cd, Ni, Cr, Ag, Al, Mo, Ba).




HVG-A
Suitable for the analysis of metal hydrides in some elements that can easily form gaseous states with hydrogen atoms. (e.g. As, Hg (cold atom method), Se, Sn, Bi, Sb).
The elements to be measured in the samples were analyzed in the ppb level.
