Flame Furnace Atomic Absorption Spectrophotometer
Flame Furnace Atomic Absorption Spectrophotometer TT-AAS
Flame Furnace Atomic Absorption Spectrophotometer TT-AAS adheres to the ASTM D4628 Standard Test Method for Analysis of Barium, Calcium, Magnesium, and Zinc in Unused Lubricating Oils by Atomic Absorption Spectrometry.
During fuel combustion, metals within the fuels can create corrosive low melting compounds that pose a threat to metal components. Additionally, trace metals found in petroleum can hinder catalysts during processing. These test methods offer a quantitative means of determining the concentrations of vanadium, nickel, iron, and sodium. Consequently, they serve as valuable tools in assessing the quality and value of both crude oil and residual oil.
1. High-precision automatic optical system.
2. Polymer spray chamber made of materials resistant to corrosion from acids and alkalis.
3. Titanium burner with options for 50mm and 100mm burners.
4. Automatic analysis capabilities, including safety ignition, extinguishing, and switching. The structure is reliable with a low fault rate, ensuring sensitivity and reproducibility of the flame method. The light source system features six-lamp automatic conversion, allowing for the direct use of high-performance hollow cathode lamps, enhancing flame analysis sensitivity. It also includes automatic adjustment of power supply parameters and beam position, as well as automatic wavelength scanning and peak searching.
