What is an atomic absorption spectrophotometer?
Atomic absorption spectrophotometer is a device that can detect an element or substance by evaporating it and measuring in what part of the spectrum it absorbs light. Measurements are usually marked with a black line in a certain part of the light spectrum. The device can operate using a flame or heated graphite tube. It usually includes a cathode light tube, a prism or an optical filter for the selection of wavelengths and a photo detector. The digital display is sometimes used to design the results of the experiment or the computer can also be connected to the system. The light beam, set to a specific wavelength, shines through steam and atomic absorption spectrophotometer. The intensity of the light can change when the atoms in the material is absorbed. Such a spectroscopic tool can be used to detect heavy metals in an environment such as in water, soil or rocks. It can also be used in the oil of achemic plants and in the production of semiconductors.
in the atomic absorption spectrophotometer, a burner consisting of a flame or a heated tube evaporates the sample, while the light shines with the cathode tube. The light passes through the flame and then the component called the monochromator. The lenses in this section usually act as a prisms for filtering a specific wavelength and can also filter the scattered light that could disrupt the measurement. The light intensity can then be detected by a photomultuctors. Traditionally, it was a vacuum tube as a device, but the 21st century technology. It was often replaced by microchips and electronics in a solid state.
Modern atomic absorption spectrophotometer tools are often controlled by a computer with specialized software that can run on common operating systems. Spectrophotometers are generally very sensitive to minute traces of materials. Such tools can measure the presence of metals in parts per million, while the inclusion of graphite furnaces can increase sensitivity to parts to a billion.
using atomicAbout the absorption spectrofotometer requires knowledge of how to read the results of the experiment. When the sample is lowered, the absorbance values can be calculated by software based on spectral values. It is usually necessary to compare with previously generated calibration curves. Comparing the results with known values can help to understand the results of the test exactly. With this tool you can directly identify about 70 elements along with different materials that could contain any combination of them.
