Heating to a temperature range from 140 to 200[degrees]C for 10 min will make the chemisorbed molecules start to desorb
or decompose, but a heating above 220[degrees]C will totally destroy the dodecanoic acid layer in a short time.
The introduction of oxygen into this reaction causes an increase in the formaldehyde production and effectively quenches the production of formic acid yet has little or no effect on the temperature at which the products desorb
When relative humidity changed, the plastic molding would either absorb or desorb
The product also will not desorb
whatever liquid absorbs from the body.
3] film; those that enter the film, but return to the surface; and H atoms that desorb
from the molten aluminum bath and find their way through the surface film.
The company provides engineered media formulations that remove contaminants through a chemisorption process, which traps the gases within the pellet, converting them into a harmless solid that will not desorb
back into the airstream.
During the pyrolysis process, water molecules will first be lost from the biomass, and then organic compounds will desorb
from the biomass by volatilization processes.
The temperature of Adsorber 2 increased and caused the methanol to desorb
from the activated carbon.
This data represent the best estimate characterization for how these coatings absorb and desorb
moisture during the diurnal cycle in the southern Florida outdoor exposure environment.
The purge-and-trap procedure included a standby temperature of 35[degrees]C, purge time of 10 min, desorb
preheat of 160[degrees]C, desorb
of 4 min at 175[degrees]C, and bake time of 4 min at 260[degrees]C.
Also, as the sample passes more rapidly through the column, it has less time to absorb and desorb
, which can lead to less separation or efficiency.
In MALDI and DESI, "non-destructive" techniques are utilized with soft ionization sources to desorb
and ionize sample surface molecules for MS analysis.
