Graphite tube: high purity
graphite tube, C content *9% , advantages: high strength, the
maximum bending up to *0 mpa, high density, fine particles,
excellent oxidation resistance.
The atomic absorption spectroscopy is
based on the strong absorption of the resonance radiation of the
ground-state atoms of the element measured in the gas state. The
method has the advantages of low detection limit, high accuracy,
good selectivity and fast analysis speed. When the experimental
conditions such as the temperature absorption path and the
injection method are fixed, the atoms in the ground state of the
element to be measured produced by the sample absorb the
monochromatic light emitted by the hollow cathode lamp of the
element as a sharp light source, the absorbance (a) is proportional
to the concentration (c) of the element in the sample. In the
equation a = kc, k is constant. According to this, by measuring the
absorbency of standard solution and unknown solution, and knowing
the concentration of standard solution, we can make a standard
curve and get the concentration of elements to be measured in
unknown solution.
