Atomic Emission Spectroscopy (AES) enables the analysis of alkali and alkaline earth metal concentrations in aqueous solutions. Nowadays, elemental analysis is frequently performed by using complex techniques such as AAS, ICP-OES, Titration or with ion-selective electrodes.
Now a change is emerging, and the proven measurement technology of AES flame photometry replaces these often very expensive and time-consuming techniques. KRÜSS flame photometers provide maximum measurement accuracy while maintaining highly economical operating costs. Measurements are conducted in full compliance with international norms and standards, including GMP/GLP and 21 CFR Part 11.
Another advantage: the consistent modernization of KRÜSS flame photometers and the dedicated focus on safety concepts open up completely new application fields for cost sensitive customer segments – it ranges from automated incoming goods inspection up to the qualification of FFP masks in accordance with DIN 149.
Flame Photometer: Measurement Principle at a Glance
The basic principle of flame photometry measurement (AES) is known from chemical laboratories:when alkali or alkaline earth metals are introduced into a hot flame, they emit a flame colour characteristic of the respective element.
In AES laboratory measurements, the analytical substance is aspirated as an aqueous solution at the touch of a button. This aerosol is sprayed into a low-luminous flame. The thermal excitation causes the atoms to emit light at their characteristic wavelengths.
The emitted radiation is selected and analyzed and determined with the help of a detector.

More InformationModern AES flame photometers uses multiple detectors simultaneously, so the simultaneous determination of multiple elements is possible. In addition, our flame photometers automatically calculate the necessary curve adjustments to compensate for nonlinear effects, ensuring high quantitative precision.
Strengths of KRÜSS flame photometers - Cost-efficiency. Safe. 24/7 analyses
Low operating costs are one of the main strengths of flame photometry. In addition, the technology of the FP8000 series excels with high determination accuracy for Na, K, Li, and Ca, along with high measurement throughput.
Completely modernized and with enhanced safety concepts, the FP8000 series enables automated operation in autonomous mode. This means analysis is possible 24/7 without the presence of laboratory personnel.
Automated Safety, simplified operation and exceptional economy:
KRÜSS flame photometers require only minimal training, because the measurement technology is straightforward. In particular, the devices of the FP8000 series feature automated safety mechanisms and intelligent measurement data evaluation.

More InformationOperating costs per measurement in the single-digit cent range
Flame photometry (AES) is an extremely cost-efficiency measurement method. The operating costs per measurement are in the single-digit cent range. This is due to the low consumption of required standards and gases, as well as the uncomplicated and low-wear measurement operation.
In alternative AAS measurements, for example, replacing the hollow cathode lamp used for one of the elements to be tested, alone can cost several hundred euros. Combustion gases used in flame photometry, such as propane or acetylene, are inexpensive and easy to handle.
Additionally, AES eliminates the need for costly disposal of hazardous reagents and reaction products and standards,. All this is making flame photometry more a sustainable alternative to other methods. In the KRÜSS online store you can order calibration solutions, standards, accessories and consumables quickly and easily.
