31. The isosbestic point occurs where the acid and basic forms and mixtures thereof have the same absorbance 32. You ought to be able to estimate the absorbance from the electrical resistivity given in matweb. 33. Tartrazine is water-soluble and has a maximum absorbance in an aqueous solution at 425 nm. 34. Usually proteins are detected as they are coming off the column by their absorbance at 280 nm. 35. Then, using a spectrophotometer, they were able to measure the light absorbance of the pigments. 36. It is soluble in water; in solution, its maximum absorbance lies at about 504 nm. 37. Transmittance and absorbance of light are related and can be converted according to Beer's law. 38. These pigments have maximal absorbance at wavelengths corresponding to 350 nm, 440 nm, and 540 nm. 39. This allowed Wald to determine the absorbance of pigments in the cone cells ( Goldstein, 2001 ). 40. The principle of operation is based on the measurement of a decay rate rather than an absolute absorbance .
