Flame photometer FP8700

Flame photometer – Automatic unit with dilution FP8700

Automated process for operation with high sample throughput

The flame photometer FP8700 is the laboratory version supplemented by a rotation sampler, diluter, and mixer. Ideal for applications with high sample volumes and high concentrations requiring dilution. Various safety mechanisms ensure particularly high operational safety.Especially control laboratories and testing offices benefit from this independent operation. 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
  • Automatic dilution
  • Automatic sample feed
  • Suitable for high sample throughput and small sample volumes
  • Little care needed by users
  • 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.

Samples and substances often analyzed with a flame photometer
