Four related ambient ionization methods that have been used to characterize tissue by mass spectrometry of desorbed or dissolved molecules.
Heavy metal such as Cu(II) can be adsorbed into the soil and desorbed under certain conditions [17].
Therefore, the higher the gas solubility in water is, it is easier for gas to desorb, the higher the gas permeability is, and the greater the pressure drops of gas phase.
Quantitatively, the dosage rate of 1.25 g of SP per kg of cement ensures around 495 g of water per cubic meter of concrete available for internal curing since SP can desorb more than 90% of absorbed water.
Many food packaging materials used by the refrigerated food industry are hygroscopic and adsorb or desorb water depending on the conditions they experience as they pass through the cold chain.
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.
In the desorption stage, an alkaline solution is passed through the column and the phosphate ions are desorbed. The adsorbent can then be used again in the adsorption stage.
The analyte molecules need to be in close proximity to the matrix molecules to be effectively desorbed. The only source of energy in the experiment to induce desorption is the laser light.
Formaldehyde desorbs from the surface at 320K and 510K and formic acid at 270K and 670K.
The collecting mechanism consists of a single-stage pre-concentrator that traps vapor and particles from the sample and then desorbs them into the detection system.
"The dissolved oxygen desorbs from the water, passes across the membrane into the sulfite solution where it is destroyed," Johnson said.
