FIELD: spectrophotometry. ^ SUBSTANCE: device has halogen lamp and second emitter, both mounted on same optical axis, while second emitter is made in form of transparent electrode-less gas-metal fill lamp with high-frequency inductor, both emitters and inductor are positioned coaxially in such a way, that halogen lamp is mounted beyond grounded end of inductor, and electrode-less lamp is mounted in maximum of high-frequency electromagnetic field of inductor before its ungrounded end. Electrode-less lamp can be made in form of quartz reservoir, containing xenon Xe, mercury Hg, cadmium Cd, and zinc Zn. ^ EFFECT: expanded working spectrum range, higher sensitivity, higher precision. ^ 2 cl, 1 tbl, 3 dwg |
