    Desorption electrospray ionization DESI is an ambient ionization technique in which charged solvent droplets are made to hit the sample surface with rapid formation of analyte ions after the subject hits the sample surface. The main working of DESI is based on the mechanism of electrospray ionization with an analytical strategy of direct desorption/ionization, and it is extremely suitable

    Figure 6 shows the dramatic laboratory results obtained by adding 20% ethyl alcohol to a Zadra solution. Several different alcohols were investigated. Methanol, ethanol, and Isopropanol were all found to increase the gold desorption rate. Ethanol and methanol were found to perform almost equally, but were substantially better that Isopropanol.

  • Pressure Swing Adsorptionan overviewScienceDirect Topics

    When column 2 is pressurized, column 1 is depressurized to ~1 atm and carbon dioxide is separated from the flue gas. For the desorption steps, the inlet CO 2 gas stream is stopped and N 2 is only introduced to desorb CO 2 after depressurization. The cycle continues as a switching mode from adsorption column to desorption column.

  • AdsorptionWikipedia

    Adsorption is the adhesion of atoms, ions or molecules from a gas, liquid or dissolved solid to a surface. This process creates a film of the adsorbate on the surface of the adsorbent.This process differs from absorption, in which a fluid the absorbate is dissolved by or permeates a liquid or solid the absorbent, respectively. Adsorption is a surface phenomenon, while absorption involves
