Atomic absorption spectroscopy (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. In effect, AAS takes advantage of the different radiation wavelengths that are absorbed by different atoms.

(A) SPECIAL FEATURES 

1. High light throughput, single-path optical system with a dual-blazed grating monochromator for optimized performance over the entire AA wavelength range.
2. Front-surfaced, reflecting optics with protective coatings for improved UV reflectivity and corrosion resistance are used throughout.
3. Complete system control from a single keyboard; automated motorized atomizer exchange, permitting the change between flame AA and graphite furnace AA.
4. THGA-type furnace with Zeeman-effect background correction is mounted on a motorized carriage that can be moved automatically into the sample compartment with a push of a button.

(B) APPLICATIONS 

1. Chemical Analysis
2. Elemental Analysis
3. Wastewater
4. Fertilizer and pesticide
5. Water
6. Food and beverage
7. Clinical Research

(C) SAMPLE REQUIREMENT 

1. Liquid
2. Solid - can digest using our Microwave Digestion
