Flame photometer FP8500

Flame photometer for process FP8500

Process version

The FP8500 combines the characteristics of the FP8400 with an automatic calibration to realise a 24 hour fully automated measurement operation; measuring times between 1 second and several minutes are possible. For data transmission, a variety of interfaces are available. 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
  • Remote control of several devices via central process computer
  • Suitable for 24-hour operation
  • 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

  • Process analysis
  • Process monitoring
  • Online measurement
  • Automated continuous measurement

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