Monolithic Material Sorptive Extraction MonoTrap

Sampler for Skin Gases MonoTrap SG DCC18

MonoTrap SG DCC18 is a sampler for skin gases to use monolithic silica adsorption with high adsorption efficiency, and enable to adsorb diffusion gases from the skin out of touch with human body but adsorb in space from surface of the skin.

How to Use

Adsorption of skin gas from arm

Take out the collection patch from the transport/extraction vial, and fix at position where it is to be collected skin gases. After collection, it can be stored by attaching it to the transport/extraction vial. Use of medical tape is recommended for attachment.

Extraction

Remove the collection patch from the transport/extraction vial and pour the extraction solvent into the transport/extraction vial. The collection patch is then mounted upside down, solvent extraction is performed by ultrasonic irradiation, and the collected components are extracted into a solvent.

Application

This is the result of the GC/MS analysis after placed MonoTrap SG DCC18 to the neck on 45 years old man, then solvent extraction is performed by ultrasonic irradiation.

Calculation of Skin Gases

From adsorption amount analyzed using GC/MS analysis: W (ng), adsorption time: t (hour), surface area of MonoTrap SG DCC18: S (cm2), desorption flux amount: E can be calculated. The result of desorption flux of diacetyl calculated on each body sites. The flux value is different between sites to sites.
