GLOW DISCHARGE LAMP

The utility model relates to a glow discharge lamp, comprising components of an anode, a sample bracket, a quartz sample push rod, an air inlet, an air exhausting outlet, etc. The utility model is characterized in that the anode is a hollow cylinder with inversely placed round desk shape, and a quartz ring and an insulating cushion are respectively installed between the anode, a test sample and a test sample push rod. The glow discharge lamp of the utility model not only has simple processing and low cost, but also saves a vacuum pump. As the utility model adopts the quartz ring to limit the discharge area, the utility model can analysis plate-shaped test sample and as well as can analysis spherical face-shaped test sample, making the glow discharge lamp have greater development inapplication.
