The Spectroflame is a simultaneous ICP-emission spectrometer with which up to 48 elements having analytical lines at wavelengths between 165 and 800 nm can be determined. It can be extended with a monochromator for flexible sequential determinations. It is a routine instrument including automated plasma ignition and operation in dialogue with a computer via a video display. The software allows control of the instrument and the calculation of analysis results being presented on a printer. The spectrometer may have up to five optics with a focal length of 0.75 m and Paschen-Runge configuration. Several gratings are available and the wavelength coverage may be from 165 to 800 nm. The air polychromators can have 1800, 2400 or 3600 lines/mm gratings and the vacuum polychromators 2400 or 3600 lines/mm gratings. The monochromator has a 2400 lines/mm grating. High stability of the spectrometer is obtained without need of thermostatization. The vacuum system includes oil rotation pumps and a vacuum control system allowing interval operation. The radiation emitted by the ICP is transmitted to the spectrometer via optical fibres. Accordingly, it is possible to measure by means of separate spectrometers the line and background intensities simultaneously. The 27.12 MHz h.f.-generator has a maximum output power of 2.5 kW. It may be varied continuously and is stabilized. A demountable torch, various nebulizers and a Scott-type spraychamber are used. A sample introduction system for work with hydrofluoric acid, an automated sampler, a hydride system and a peristaltic pump are optionally available. The measurement electronics include up to 48 integrators with high dynamic range. The computer has a Z 80 B CPU with 128 k-Byte RAM and 8 k-Byte EPROM and 12-Bit A/D conversion. Peripheric instrumentation comprises 2 floppy-disc drives, an Epson printer, a keyboard, a 30 cm Video display and a V 24 interface. An extended analytical software package is offered.
