Abstract

PURPOSE:To secure the high-temperature and steady stoichiometric state for the metal to be measured by cutting off the air current which is liable to mix into the frame formed on the photometric path, thus increasing the sensitivity for the atomic absorption (emission) analysis using the gas frame. CONSTITUTION:Glass 11 and 11 are stuck to face 10, where the optical path passes, of the noncombustible structure component which possesses opening part 8 at the bottom surface along with windbreak walls 9 and 9 provided at both sides. The device of such constitution is fixed by close adhesion onto the burner in such way that the slit of the burner may be positioned under part 8, and thus can be used for the atomic absorption (emission) analysis. In the case of the measurement outside the ultraviolet range which is affected by the light absorption via the glass, slits 12 and 12 are provided in place of glass 11 and 11. Thus the inactive gas is sprayed in a high speed through the slits to form the gas curtain which prevents the mixing of the air.
