Product Description

Wayeal Flame Atomic Absorption Spectroscopy AAS Atomic Absorption Spectrophotometer Machine for Metal Analysis

Product Introduction

Atomic absorption spectrophotometry analyzes the concentration of elements in a liquid sample based on energy absorbed from certain wavelengths of light (usually 190 to 900 nm). Atomic absorption spectrophotometers typically include a flame burner to atomize the sample (most commonly a hollow cathode lamp), a monochromator and a photon detector. Depending on the model, some atomic absorption spectrometers are equipped with a turret or fixed lamp socket that can hold multiple lamps (up to eight) to reduce downtime between samples or allow for sequential analysis.

Specification

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

Foods and Beverages – In synthetic processed foods, metal pickup takes place due to contact with processing equipment and catalytic conversions. Consumer awareness on food safety is increasing by the day so manufacturers have to ensure that the trace metals do not exceed the permissible limits and this requires rigorous quality control through atomic absorption spectroscopy and other sophisticated instruments.

Oil and Petroleum – Both edible oils and mineral oils require refining before consumption. Such refining operation can involve distillation as well as catalytic refining. Uptake of metals during such operations can lead to deterioration of performance or consumer hazards. Trace metal analysis of engine oil provides useful diagnostic information on the wear and tear of engine parts.

Agriculture – Trace metal constitution of soils in addition to their acidic or basic nature is essential to establish their
productivity and nutrient value. Trace metal composition of plants (leaves, stems and roots) gives a fair idea on how the uptake of minerals gets distributed under different growth conditions

Forensics – Trace metal analysis provides valuable information on specimens such as stomach contents for food poisoning, paint chips, fibres and hair strands collected from the scene of a crime

System Configuration

Flame Atomic Absorption

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

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.
