DEVICE FOR DETECTING ELEMENT OF EXTREMELY LOW CONCENTRATION BY ATOMIC EMISSION SPECTROMETRY

摘要

PURPOSE: To provide a spectrometric low voltage lamp device with a low detection limit further exceeding the detection limit obtained by a conventional device for introducing a microwave through a coaxial cable. ;CONSTITUTION: A microwave generating source 9 is mounted on the large walls 2, 3 of a parallelepiped chamber 1 with an antenna 10 being protruded to the interior side by a distance equal to 1/3 of a microwave wavelength, and a negative electrode 7 is mounted on the large walls 2, 3 with a space from small walls 4, 5 by the distance equal to 0.930 times the wavelength.;COPYRIGHT: (C)1994,JPO
