    Description

    The AAS/Flame instrument determines the concentrations of an element in aqueous solution, by sending an atomized sample through an acetylene flame. Measurement is accomplished by observing the absorption at its characteristic wavelength. Concentrations are calculated by comparing to known standards. Metals analyzed using the Flame AAS include calcium, cesium, iron, magnesium, potassium, sodium, and zinc.

    Analytical Method-AAS Flame: Our laboratory follows Standard Methods for the Examination of Water and Wastewater, 23rd Edition. Metals using the flame AAS are analyzed using 3111B direct air-acetylene flame. Samples require filtration using a 0.45┬Ám filter, and the pH is adjusted to 2.5 using nitric acid.

    The AAS/Furnace determines the concentration of an element in aqueous solution by injecting the sample onto a graphite platform. To eliminate most matrix effects, the temperature is ramped, and after rapid heating to the temperature at which the element is atomized. and the element's characteristic wavelength, the absorbance is recorded and the concentrations are calculated by comparing to the absorbance of known standards. Metals analyzed using the Graphite Furnace AAS include aluminum, antimony, arsenic, barium, beryllium, cadmium, chromium, cobalt, copper, lead, manganese, nickel, molybnum, selenium, silver, strontium, tellurium, thallium, tin, and vanadium.
