Measure up to three alkaline elements simultaneously
Krüss offers the Flame Photometer model FP8800 for simple, precise, cost-effective measurement in industrial applications.
Ideal for concentrated alkaline elements. In aqueous solutions, the unit will deliver a rate of around 300 samples per hour.
A unique feature world-wide!
Utilising propane or butane as a fuel gas, the FP8800 gives flame-photometric measuring of up to three elements simultaneously (purified and dried air is required), allows 99 definable methods, and stores the last 999 measurements. The device can be easily customised to suit user requirements, and for traceability of results, it has the facility to export data via USB port, PROFIBUS DP, RS232 or ethernet interface for computer aided process control (SPC).
The FP8800 has 4 independent measuring channels and an additional separate channel for the monitoring of the flame. The 4 measuring channels can be equipped with the appropriate optical filters. The FP8800 does not require a spectral reference line, although measurement operation can be carried out either with or without a reference element.
This established and proven measurement technique in combination with modern instrument electronics and innovative process control makes the FP8800 an essential component of measurement procedures in the named application areas.

Flame photometry and flame emission spectroscopy compared
Although in principle quite similar, flame photometry and flame emission spectroscopy each offer specific advantages and find their own place on the analytical laboratory bench. Where the flame emission spectroscope offers the potential for more detailed analysis of a wider range of samples, the flame photometer provides a robust and economical instrument to determine the presence of concentration of several common elements found in industrial and pharmaceutical processes.
Flame photometers are most commonly used to detect and quantify the presence of the alkali metals lithium (Li), sodium (Na), and potassium (K), and the alkali earth metals calcium (Ca), and barium (Ba). Rubidium (Rb), caesium (Cs), and strontium (Sr) are also readily detectable by this method.
Because these elements emit light (photons) within the visible range at relatively low temperatures, an inexpensive heat source – propane, butane, or natural gas – can be used to excite them. Typical flame photometry operations ‘burn’ the sample at 1500-2000 °C. Sample preparation is straightforward, involving making the sample completely aqueous using deionised water before introducing it the flame photometer. The photodetector records and measures the resulting radiation, and the digital display provides a readout of element concentration to within 0.5%. Usual laboratory practices must be adhered to, especially in maintaining the cleanliness of the sample and the diluent, to obtain reliable results.
