Application Source Lamps have 6 individual cathodes in a single envelope. This design provides either 6 single elements with the same spectral purity and intensity as a single element lamp - or 2 or more elements per cathode, allowing many analytical laboratories to have all their element range provided for in one longer life lamp. Choose from 11 standard Application Sources or design your own. Currently this lamp is only directly usable in a GBC® 932, 932plus and a Sensor® AA atomic Absorption Spectrophotometer.
