Six lamp, single graphite furnace atomic absorption spectrophotometer

Product Introduction:
The multifunctional atomic absorption spectrometer mainly uses flame atomic absorption analysis method, and also has multiple functions such as flow injection hydride atomic absorption method and graphite furnace atomic absorption method. It is currently a large precision analytical instrument with more functions and higher cost-effectiveness among similar instruments at home and abroad.

Instrument classification:

Six lamp, single graphite furnace atomic absorption spectrophotometer

The advantages of flame atomization method are: easy operation, good reproducibility, large effective optical path length, and high sensitivity to most elements, making it widely used. The disadvantages are: low atomization efficiency, insufficient sensitivity, and generally unable to directly analyze solid samples;

The advantages of graphite furnace atomizer are: high atomization efficiencySample utilization rate at adjustable high temperatureReaching 100%, with high sensitivity and minimal sample usage, suitable for the determination of refractory elements. The disadvantages are: the uneven composition of the sample has a significant impact, the measurement precision is low, the interference of coexisting compounds is greater than that of flame atomization method, the interference background is more severe, and generally requires background correction.

Application scope:

Atomic absorption spectroscopy analysis has been widely used in various analytical fields, mainly in four aspects: theoretical research; Elemental analysis; Organic matter analysis; Chemical speciation analysis of metals.

Measurable trace elements:

The element detected by atomic absorption graphite furnace method has a small injection volume and high sensitivity (PPb level).
