Plamenski fotometer FP8600

Plamenski fotometer FP8600

The A.KRÜSS flame photometers (AES) determine the concentration of alkali and alkaline-earth elements in aqueous solutions. They are a simple and cost-effective alternative to ICP or AAS. They suit quantitative determination of sodium (Na), potassium (K), lithium (Li) and calcium (Ca), measured simultaneously in one step. Operating costs are about 1 cent per measurement and up to 120 measurements per hour are possible; the modular design allows expansion with retrofit kits. FP8000 series: detection limit for Na, K, Li and Ca of 0.01 mg/l, accuracy up to 1 % at 40 ppm.
