Emission spectrometry is to calculate the content according to the intensity of the measured spectral characteristics of atoms or molecules in the excited state emission. Absorption spectroscopy is based on the spectral characteristics of the analyte butyl acetate manufacturers, through sample vapor in the ground state atomic absorption spectra measured analyte elements after the weakening of the strength calculation of its content. It meets Lang Perot - Beer's Law: A = -lg I / I o = -lgT = KCL formula I is transmitted light intensity, I0 is the emission intensity, T is transmittance, L is the optical path length through the atomizer due to L is a constant value so that A = KC. Physical principles are: atomic nuclei are made of any element and the movement of electrons around the nucleus of the atom extranuclear their level hierarchical distribution of energy and the formation of different levels Jinan butyl acetate, therefore, can have a nucleus many state level. Spectroscopic methods, depending on the manufacturer direct butyl acetate, it is customary to distinguish emission spectroscopy spectroscopy, absorption spectroscopy and scattering spectroscopy. These different types of spectroscopy, providing material microstructure of knowledge and different methods of chemical analysis from different aspects. The wavelength of the emission spectrum of the spectral distribution regions of the spectrum can be divided into three different categories: linear spectrum, band spectrum and continuous spectrum. Linear spectrum is mainly produced in atomic, molecular band spectrum is mainly produced in the sec-butyl acetate, mainly produced in the continuous spectrum incandescent solid or gas discharge. Now observed atomic emission spectral line has been millions of. Each atom has its own unique spectrum, like human fingerprints are not all the same. According to the theory spectroscopy, each atom has its own series of discrete energy states, each state can have a certain energy.
