desorb /diːˈsɔːb /verb [with object] Chemistry1Cause the release of (an adsorbed substance) from a surface: these ‘active points’ desorb the resultant alkane...- The electrochemical data suggest that the bilayer is desorbed from the electrode surface at this potential.
- This was followed by plasma desorption in the 1970s, which uses high energy ions to desorb and ionise molecules.
- As the ion beam hits a small patch of the sample surface, it desorbs and ionizes the atoms in its path.
1.1 [no object] (Of an adsorbed substance) become released: the free radicals desorbed back into the chamber...- In the case of the early lengthening steps, the value of L p is low, suggesting that perhaps half of the structure either unfolds or desorbs to a random coil configuration with little hindered movement.
- Ribosomes that reach the termination site desorb and re-enter the pool of diffusing ribosomes.
- Aggregation of the cells occurs at the highest C, here most likely because poly-L-lysine desorbs from the saturated glass and begins to cross-link the red cells.
Derivativesdesorbent adjective & noun ...- The desorptive characteristics of three potential desorbents for metal recovery were assessed.
- The desorbent has surprisingly high strength and selectivity characteristics with the preferred desorbent.
- The feed and desorbent are supplied continuously and at the same time extract and raffinate are drawn continuously through the ports.
desorber noun ...- We used a thermal desorption unit double-stage desorber to transfer compounds from the 2-mm Carbotrap to a gas chromatograph or a GC-mass spectrometer.
- The chemical analysis of VOCs was carried out with thermal desorption gas chromatography and an automatic thermal desorber coupled to PE 8700 gas chromatograph.
- Sample injection was achieved via automatic thermal desorber, and detection was accomplished by a flame ionization detector.
desorption /diːˈsɔːpʃ(ə)n / noun ...- The land was then treated by a variety of methods, including solidification, bioremediation and indirect thermal desorption.
- However, as both species start to reach equilibrium, the reverse rates make themselves felt and the less-strongly bound species B begins to come off the surface again, reversing the rate of adsorption to a net desorption.
- A tool has been developed to measure the concentration of hydrocarbon compounds in a nitrogen-purge gas flow to the level of parts-per-thousand by using thermal desorption and gas chromatography.
