| The Cd concentration was measured according to a modified deproteinization method using a flameless atomic absorption spectrophotometer. |
| The absorbance of the product dye at 540 nm was measured using a flow-through spectrophotometer. |
| Atomic absorption spectrophotometer meeting the requirements of the method with regard to sensitivity and precision in the required range. |
| Reactions were mixed by inversion several times and then placed in a dark chamber with constant stirring in a luminescence spectrophotometer. |
| Spectroquant® Pharo spectrophotometers combine the advantages of a system photometer and the versatility of a spectrophotometer. |
| We measured those colours with the spectrophotometer and plotted them in one of these diagrams we've been talking about. |
