Slope of the graph = Linear absorption Coefficient (𝜇) an 𝜇/𝜌 = 𝜇m= Mass absorption Coefficient When you need to solve a math problem and want to make sure you have the right answer, a calculator can come in handy. Calculators are small computers that can perform a variety of calculations and can solve equations and problems. While th Percentages may be calculated from both fractions and decimals. While there are numerous steps involved in calculating a percentage, it can be simplified a bit.
The entered wavelength is used to iterate through an array to find the closest wavelength that has a measured kappa value. While the SI unit is the absorption cross-section σ, the extinction coefficient ε (epsilon) is more often used. Typical ε values for visible wavelength absorption maxima are of the order of 1000 - 100,0000. A related calc can be used to calculate concentration from known OD, path length and absorption coefficient. First, determine the coefficient. Calculate the molar absorption coefficient of the substance.

This database can be used to calculate photon cross sections for scattering, photoelectric absorption and pair production, as well as total attenuation coefficients, in any element, compound or mixture, at energies from 1 keV to 100 GeV. This is a web version of the PC based program XCOM (also called NIST Standard Reference Database 8 - XGAM). The absorption coefficient determines how far into a material light of a particular wavelength can penetrate before it is absorbed. In a material with a low absorption coefficient, light is only poorly absorbed, and if the material is thin enough, it will appear transparent to that wavelength.
