Suitable for analysis of all (laboratory) wort samples
Atomic emission spectroscopy, also known as optical emission spectroscopy, in conjunction with inductively coupled plasma (ICP-AES or ICP-OES) is a technique used to determine and measure elements based on the phenomenon of atomic emission. The solutions to be analyzed are nebulized and the resulting aerosol is transported with the help of a carrier gas into an inductively coupled plasma (ICP). There, the elements are excited to a higher energy state, causing emissions. The spectrometer separates these emissions into individual wavelengths, and the intensities of the spectral lines of the element are measured with detectors (photomultipliers). A qualitative measurement is possible by calibrating the instrument with reference solutions, whereby a linear relationship exists over a broad range (generally several orders of magnitude) between the intensities of the emission lines (spectra) and the concentrations of the elements.

Inductively coupled plasma atomic emission spectroscopy (ICP-AES) is an analytical technique for detecting and determining concentrations of elements by measuring their line-emission spectra. The solution under analysis is atomized and the aerosol is transported into an inductively coupled plasma (ICP) with the aid of a carrier gas at which point the elements enter an excited and unstable state. When they return to their ground state, the atoms radiate. Their emission spectra are measured using a spectrophotometer. The intensity of the emission spectra is measured with detectors (photomultipliers). Quantitative results are possible through calibration with a standard, though over a wide range (normally multiple orders of magnitude) a linear relationship between the intensity of the line-emission spectra and the concentration of the elements exists. The elements can either all be determined simultaneously or each one sequentially.
