Popis:	A device is described which provides continuous sample introduction into a low pressure glow discharge. A chain conveyor is used for sample transport. Results are reported for aqueous Pb sample solutions. The device is shown to give a linear response for Pb over approximately 2 orders of magnitude in concentration. A limit of detection of 0.9 μg ml is reported. The device is shown to possess many useful features. Its potential utility as an element selective detector for liquid chromatography is suggested.
