Voorbeeldzinnen

1. Optical density levels
2. From the specific optical density
3. Development of coloration and measurement of optical density
4. E corrected optical density, determined as indicated in 5.2,
5. Measure the optical density as indicated in 5.2.
6. Soil increases the optical density of euro banknotes.
7. Subtract the optical density of the blank test solution from that of the sample solution (= corrected optical density).
8. "Equivalent Density" (6) means the mass of an optic per unit optical area projected onto the optical surface.
9. Determine the optical density of the blank test solution (D) by comparison with the reference solution (C), and the optical density of the sample solution (B) by comparison with the reference solution (A), in the spectrophotometer at 440 nm using 1 cm glass cells. Subtract the optical density of the blank test solution from that of the sample solution (= corrected optical density).
