Spectral DISCHARGE LAMP FOR atomic absorption

摘要

The spectral lamp for atomic absorption, comprising misalignment with cathode pin anode and hollow cathode is placed in the filled inert gas glass flask, characterized in that the cathode length L and outer diameter D is made of oxidized (oxidized) aluminum and placed in the glass flask through the wall in which the cathode cavity to a depth equal to 1 / 5D, includes a discharge tube length of 6 / 5L diameter d, smaller than the inner diameter of the cathode, with the two spaced apart along the length of the discharge tube taps, and closed at the opposite Art Oron uviol glass window, wherein the anode is arranged in a glass retraction closest to uviol glass, at a distance of 1 / 3L from it, and the metal vapor source whose spectrum is to be obtained is located in another challenge at a distance 1 / 2L from the window.
