Anhui graphite graphite tube pipe prices
Henan Henan graphite tube manufacturers offer a graphite tube, by heating points: Portrait heated graphite tube, transversely heated graphite tube 2, according to the performance points: Ordinary graphite tube (non-pyrolysis) suitable for low temperature (≤2000 ℃) atomic elements such as silver, cadmium, lead; pyrolytic graphite tube for low, medium and high temperature (> 2500 ℃) atomic elements; platform graphite tube suitable for medium and low temperature (≤2400 ℃) atomic elements. Measured ground state atomic elements by atomic absorption spectrometry is noted in the gaseous state according to the atomic resonance radiation elements have strong absorption established. The method has high accuracy and low detection limit, selectivity, rapid analysis and so on. When the temperature of the absorption pathlength, experimental conditions such as the injection mode is fixed, the sample analyte with the ground state atoms produced as a sharp line on a light source of the element hollow cathode lamp which produces monochromatic radiation absorption, its absorbance (A) and the concentration of the element in the sample (C) is proportional. I.e., A = KC where, K is a constant. Accordingly, by measuring the absorbance of the standard solution and the solution is unknown, but already known to the concentration of the standard solution can be used as a standard curve, obtained by an unknown concentration of the analyte solution. Trace and trace components analysis of the method is mainly applied in the sample. Measured ground state atomic elements by atomic absorption spectrometry is noted in the gaseous state according to the atomic resonance radiation elements have strong absorption established. The method has high accuracy and low detection limit, selectivity, rapid analysis and so on.
