A.KRÜSS Flame Spectrophotometers

Digital Flame Photometers for Laboratory Use

Flame photometry is one of the most effective methods in simultaneously determining the concentration of Potassium (K), Lithium (Li), Sodium (Na), Calcium (Ca), etc. in aqueous solutions. Exemplifying the rules of atomic emission spectroscopy (AES), flame spectrophotometers evaporate a given solution to break intramolecular bonds into free atoms. These atoms emit different radiation wavelengths, which are then measured by light intensity and color to determine specific ions and their concentrations.

At a temperature of 1900 degrees Celsius, FAES technology is able to excite the molecules with no risk of ionization, ensuring that true concentration levels are attained throughout the process. Flame AES is recognized as the reference analytical method in the analysis of alkali metals. It is also an excellent alternative to ICP and FAAS, especially in complex aqueous matrices which may be affected by ion suppression.
