desorption column for scheelite laboratory

Gas Content Estimation Using Initial Desorption Rate

The direct method of fast desorption test is the preferred method of gas content measurement. The indirect methods are based on either empirical correlations or laboratory derived sorption isotherms. Recent research has identified two new, semi direct methods of estimating total gas content using early stage gas desorption rate measurement.

Desorption

Desorption is a phenomenon whereby a substance is released from or through a surface. The process is the opposite of sorption (that is, either adsorption or absorption).This occurs in a system being in the state of sorption equilibrium between bulk phase (fluid, i.e. gas or liquid solution) and an adsorbing surface (solid or boundary separating two fluids).

Analytical thermal desorption

Analytical thermal desorption, known within the analytical chemistry community simply as quotthermal desorptionquot (TD), is a technique that concentrates volatile organic compounds (VOCs) in gas streams prior to injection into a gas chromatograph (GC). It can be used to lower the detection limits of GC methods, and can improve chromatographic performance by reducing peak widths.

Desorption an overview ScienceDirect Topics

Thus, static desorption for a preset amount of time is often used, followed by a brief dynamic desorption step, in order to sweep the desorbed analytes onto the analytical column. In static desorption, the interface is filled with a certain amount of solvent and the fibre is allowed to sit in this solvent for a predetermined amount of time.
