It may also employ volumetric methods of scanning, such as digital tomography.
2.
Volumetric method was used in the early days of adsorption studies by Langmuir, Dubinin and others.
3.
The circumferential type is more common, but the volumetric method is believed to be more accurate at low arousal levels.
4.
In a volumetric method, the volume of a solution containing sufficient reagent to react completely with the analyte is measured.
5.
The extra steps in iodometric titration may be worth while because the equivalence point, where the blue turns a bit colourless, is more distinct than some other analytical or may be by volumetric methods.
6.
Later estimates reduced this to about 3.5 metres ( 11.5 ft ) . while its body mass is estimated by pterosaur expert Mark Witton to be 7.9 kilograms ( roughly 17 pounds ) based on a volumetric method Its skull was long, low, perfectly arched, and lacked a " keel " or any other crest sometimes seen in related species.
