Flame Photometers

The flame photometers from A.Krüss are used to determine the concentration of alkali and alkaline earth elements in aqueous solutions and are a simple and particularly cost-effective alternative to analysis techniques such as ICP or AAS


Technologically groundbreaking, fast, powerful, highly accurate and with A.KRÜSS all-round service. Atomic emission spectrophotometry for determining the concentration of liquids – with high-quality new software and hardware, 2 times faster CPU and 24/7 measuring operation – delivers a measurement result accurate to 8 digits in 30 seconds and meets all important industry standards.

Detection limit, sample processing & costs

  • Simultaneous measurements of sodium, potassium, calcium and lithium are possible with a detection limit of 0.01 mg/l.
  • Our instruments offer sample throughput of up to 120 measurements per hour and have the option of fully automatic 24 H measurement operation.
  • With costs of only 1 cent per measurement, the FP-8000 series is the most economical measurement method for alkali and alkaline earth metals.

Fully automatic measurement and sample preparation

  • A measurement with atomic emission spectroscopy AES is already possible with a sample volume of only 1 ml.
  • The analysis substance is taken from the autosampler by a high-precision dosing unit and transferred to one of the 2 mixing chambers.
  • There, the substance is automatically diluted to the required concentration by adding an aqueous standby solution.

Highly accurate measurements thanks to ideal sample, gas and air mixture

  • With the aid of the Venturi effect, the analysis substance is sucked into the atomiser as an aqueous solution and atomised extremely finely.
  • Drops that are too large are collected in the atomiser chamber and discharged past a drop sensor.
    The monitoring of the reject serves as a control parameter with which the sample flow and atomisation can be optimally adjusted.
  • The finely atomised sample is mixed with the fuel gas in the gas mixing chamber to create an ideal sample, gas and air mixture.

Stable measured values through a defined flame shape

  • To achieve stable measured values, the flame must burn very evenly.
  • 12 gas outlets model a flame shape optimised for AES measurement.
  • Propane or acetylene can be used as fuel gas.
  • Air currents stabilise these and ensure a constant flame pattern, which is additionally protected by a glass cylinder.

Highly sensitive photosensors for high-precision concentration determinations

  • The elements to be measured, such as sodium, potassium, calcium and lithium, emit light with a characteristic wavelength due to thermal excitation.
  • The different wavelengths are detected by high-precision photosensors.
  • Up to 5 different elements can be measured simultaneously.
  • Alternatively, different concentration ranges of the same element can be detected.

Safety thanks to efficient cooling and monitoring

  • To increase safety for the user, an integrated cooling air flow reduces the hot exhaust air to below 50 °C.
  • In addition, our unit continuously monitors the flame.
  • In case of irregularities, the safety valves are closed automatically.
