Cl.2 H01J 61/64 G01J 3/02 Inventor: Julian Ozakow Authorized by the patent: Institute for Nuclear Research, Warsaw (Poland) Fluorescent lamp, especially for spectral analysis purposes. The subject of the invention is a fluorescent lamp, especially for spectral analysis purposes, which enables the determination of macro and micronutrients in metals and alloys as well as in samples of non-conductive materials and solutions. In addition, the fluorescent tube according to the invention may find application in microanalysis and is an improvement over the invention patented no. 101,146. Prior art. Fluorescent lamp according to patent no. 101146 zinicir in a cylindrical housing acting as an anode, the bottom cooled with water acting as a cathode. There is a cavity in the bottom for placing the test sample in the form of a disc. The cylindrical housing is provided with stub pipes for the inert gas inlet and outlet. A quartz window is placed on the opposite side of the seabed. The cylindrical housing and the bottom have channels for cooling water. In the space between the anode and the cathode, a shape made of a ceramic material is placed, and an insulating gasket banded on the side of the cathode is placed. The lamp also has vacuum seals. The fluorescent lamp is powered by a constant impulse voltage. Due to the cathode sputtering, it is necessary to clean the particle by chemical means and each time to adjust its distance from the sample, which is troublesome in routine analyzes. The mechanical resistance of the shape is also significantly reduced. 10 15 20 Summary of the invention. The fluorescent lamp according to the invention has a metal shape in the space between the cathode and the anode, an electrically insulating seal insulated from the anode, whereby the gap between the shape and the sample surface is from 0.5 mm to 5 mm. Advantageous technical effects of the invention. The fluorescent lamp according to the invention makes it possible to carry out multi-element macro and microanalysis with high accuracy and precision. The effect of accompanying elements is nothing. The structure of the lamp according to the invention enables easy and quick cleaning of the mechanically resistant shape, without the necessity to adjust its distance from the test sample each time. The shape used also creates favorable conditions for sputtering, which is essential for the transport of the sample material to the plasma and thus has a decisive influence on the results of the analysis. The subject matter of the invention is shown in an example of embodiment reproduced in the drawing, showing a schematic diagram of a fluorescent lamp. An embodiment of the invention. The cylindrical housing 1, constituting the anode, has a bottom 2 cooled with water that acts as a cathode. In the bottom 2 there is a recess 3 for the sample 4 to be tested. Moreover, the cylindrical housing 1 is provided with ports 5 and 6 marked for the inert gas supply and discharge. On the opposite side of the bottom 2 is a quartz window 7. The cylindrical housing 1 has channels 8 for cooling water, and the bottom of the cylindrical housing 1 is also water cooled. In the space between the cathode and the anode there is a shape 9, made of metal, an electrically insulating gasket insulated from the anode 12. An insulating gasket is placed between the cathode and the anode 10. The lamp also includes vacuum seals 11. The operation of the glow lamp is based on insulating gasket 10 is placed on the tested sample 4. Then the cylindrical casing 1 is connected to the bottom 2. Argon is fed through port 5 and water is supplied to cool the anode and cathode. During the measurement, the fluorescent lamp is supplied with a constant impulse voltage and a power supply, power stabilizer with a peak voltage of 1600 V, and a variator of the current intensity is read by a deflection meter. After the glowing period, the light from the fluorescent lamp is exposed to the spectrograph in a known manner. PL
