HKL-15586 AAS for metal elements in Drinking water
Overview
HKL-15586 AAS for metal elements in Drinking water conforms to the ISO 15586 Water quality — Determination of trace elements using atomic absorption spectrometry with graphite furnace. This International Standard includes principles and procedures for the determination of trace levels of: Ag, Al, As, Cd, Co, Cr, Cu, Fe, Mn, Mo, Ni, Pb, Sb, Se, Tl, V, and Zn in surface water, ground water, drinking water, wastewater and sediments, using atomic absorption spectrometry with electrothermal atomization in a graphite furnace. The method is applicable to the determination of low concentrations of elements.
The detection limit of the method for each element depends on the sample matrix as well as of the instrument, the type of atomizer and the use of chemical modifiers. For water samples with a simple matrix (i.e. low concentration of dissolved solids and particles), the method detection limits will be close to instrument detection limits.

FAQ
Q1: Which standard does this product (HKL-15586 AAS for metal elements in Drinking water) comply with?

For water samples with a simple matrix (i.e. low concentration of dissolved solids and particles), the method detection limits will be close to instrument detection limits.
Q2: What is the working principle of HKL-15586 AAS for metal elements in Drinking water?
A:Water samples are preserved through acidification, filtration followed by acid preservation, or digestion. Sediment samples undergo digestion prior to analysis. A precise aliquot of the prepared sample solution is introduced into the graphite furnace of an atomic absorption spectrometer. The furnace is then subjected to a controlled, stepwise electrical heating program, sequentially drying, pyrolyzing (charring), and atomizing the sample. This analytical technique leverages the principle that free atoms can absorb light at characteristic wavelengths. A dedicated light source, specific to the element(s) of interest, emits radiation through the atomized vapor cloud within the heated furnace. The free atoms of the target element(s) selectively absorb this light. The resulting attenuation in light intensity is measured by a detector tuned to the element’s specific resonance wavelength. The concentration of an element in the original sample is established by comparing its measured absorbance against a calibration curve generated from standards of known concentration. Potential matrix interferences can be mitigated by incorporating a matrix modifier into the sample prior to analysis or by employing the standard addition method for calibration.
