Application Notes

MonoTrap is a hybrid novel adsorbent that combines a large surface area and the properties of silica gel, activated carbon, and ODS. Utilizing the surface of porous silica, it can be used as a tool that makes use of the large surface area and the adsorbent effect caused by the inclusion of activated carbon for high collection efficiency and for short time and sensitive analysis. In this study, we used MonoTrap DCC18 (with activated carbon) to perform simple enrichment analyses of the fragrance components of bread. With the use of several low-cost MonoTrap copies per sheet at a time, warming at the time of collection and enrichment after extracting solvents, we were able to obtain high sensitivities and a lot of information. The highly inert WAX-column InertCap Pure-WAX is the optimal ...

MonoTrap is a hybrid novel adsorbent that combines a large surface area and the properties of silica gel, activated carbon, and ODS. Due to the large surface area of porous silica and the adsorption effect caused by the inclusion of activated carbon, a high collection efficiency is obtained. Therefore, high-sensitivity analysis can be performed in a short time. In this study, we used MonoTrap DCC18 (with activated carbon) to perform simple enrichment analyses of aging odors in men in their 70s. At bedtime, enrichment analysis can be easily performed by simply attaching it to the collar. We were able to identify trans-2-Nonenal, an odorous ingredient of aging. We were also able to confirm that the ingredients of the paint applied by the subjects at bedtime were also collected. Due to the ...

Therefore, high-sensitivity analysis can be performed in a short time. In this study, we used MonoTrap DCC18 (with activated carbon) to perform simple enrichment analyses of the fragrance components of domestic red wines by the HS-method. By warming to 60 ℃, we were able to obtain much information by collecting it for as short as 30 minutes, while it was HS analysis. The highly inert WAX-column InertCap Pure-WAX is the optimal column for fragrance components analyses. It is recommended to use this ...
