Used PERKIN ELMER AA #155561 for sale

PERKIN ELMER AA (Atomic Absorption Spectroscopy) is a type of spectrophotometer used to identify and quantify the constituent elements of materials such as metal alloys and organic compounds. Capable of analyzing extremely small amounts of samples, this device is widely used in various industries including pharmaceutical, environmental, materials, oil and gas, food and beverage, chemical, and metals. The basic principle of operation of a AA is that it measures a sample's absorbance of light at different wavelengths. It works by passing a light source through a narrow bandwidth filter and then against a sample of a material. As each chemical element absorbs light energy at a distinct wavelength, the sample will absorb only a small part of the energy and the rest will be reflected back. This absorption value is then compared to a reference value in order to calculate the amount of each element present. An array of lamps are used to provide the light source, and each wavelength is filtered by an arrangement of monochromators and slit-discs. This enables individual elements to be measured in the sample. As the light passes through the sample cell and onto an optical fiber, it is then directed to the photo-detector that records the absorbed light. The output is then fed to a signal processor, which records the transmittance and absorbance of the sample at each individual wavelength. The data is then collected and analyzed to create a detailed breakdown of each element present in the sample. This process is able to accurately identify and quantify the concentration of elements in a sample, which is essential for many types of analysis. The data generated by PERKIN ELMER AA can be used to generate various analytical reports. These include graphs, tables, and other graphical representations which are used to identify elements in the sample. This can be used, for example, to determine the composition of a material, or to quantify the amount of each element present in a sample. Overall, AA offers an accurate, fast and efficient way to identify and quantify the presence of various elements in a sample. Thanks to its highly sensitive nature, the device is a valuable research tool in a range of industries and applications.
