Abstract. A photoionization generator – detector of gases and vapors is developed. The instrument design, principle of operation, and performance are discussed. The possibility of using the detector in a gas chromatograph with a capillary column, for example, for medical purposes (especially in respiratory diagnostics for detection of various diseases) is considered. The detector diagram is demonstrated, elements of the chromatograph are described in detail. Presented results of experiments confirm applicability of photoionization generator – detector in capillary gas chromatography for the analysis of liquid multicomponent media.
Keywords: chromatograph, photoionization detector, ultraviolet lamp, respiratory diagnostics, potential difference
