Economic entry-level model for the laboratory

The flame photometer FP8400 is the standard version for a variety of laboratory applications and offers a very simple operation in combination with very high precision and application flexibility in determining the concentration of alkali and alkaline earth elements in aqueous solutions. With the models of the FP8000 series, A.KRÜSS Optronic presents to this day unique measuring devices for the simultaneous measurement of the elements Na, K, Ca and Li. Five measuring channels are available for this, which can be individually configured. Thanks to proven measuring methods and modern device electronics, our flame photometers achieve high-precision and reproducible measurement results and are a simple and particularly cost-effective alternative to analysis techniques such as ICP or AAS.

  • Reliable, simultaneous measurement of up to five alkaline and alkaline earth elements
  • For operation with low sample volume
  • Very high precision
  • Maximum operational safety through intelligent security mechanisms
  • User administration with two authorization levels
  • Full traceability of the measurement results
  • Extensive interfaces and convenient data transfer
  • Compliance with international standards such as GMP / GLP and 21 CFR Part 11

Typical applications

  • Quality control in the pharmaceutical, chemical, beverage, food, salt and construction industries
  • Evidence
  • Food laboratories, testing laboratories and testing offices
  • Chemical development

An overview of typical applications with the flame photometer FP8000 series can be found in our campus article on flame photometer applications.

Requirement profile

To enable us to adapt the flame photometer optimally to your requirements, we need a requirement profile in which you specify your main individual specifications (Samples, concentration, automation, etc.). A binding delivery can only take place after receipt of the fully completed profile.

Intuitive operation

Our flame photometers are easy and intuitive to operate with a large touch screen display and USB mouse.

  • User administration with two authorisation levels
  • Traceability of all measurement data and device-specific data
  • Full traceability of the measurement results
  • Extensive interfaces and convenient data transfer
  • Compliance with international standards such as GMP / GLP and 21 CFR Part 11

Unique safety concept

Automated shutdown of gases

  • At extinguished flame
  • with regular shutdown of the system
  • in case of power failure
  • at low fuel gas, oxidant or cooling air pressure
  • at low fuel gas or air pressure or failure of the cooling air

The safety functions are monitored by an independent safety circuit



Calibration, samples, controls and standards

Aqueous samples, controls and standards are measured manually or automatically. The calibration is done via the standards. The measurement results can be checked with the controls.
The emission values and concentration values of the calibration are displayed graphically and in tabular form for the check.
