Application Notes

What is MMSE? Monolithic Material Sorption Extraction (MMSE) is a novel approach for sample adsorption and extraction using monolithic hybrid adsorbent - MonoTrap.MMSE has advantages such as effective pretreatment with simple operation and high-efficiency adsorption capacity. In addition, importantly, MMSE does not require conditioning before use. What is MonoTrap? MonoTrap is a state-of-the-art silica monolithic and hybrid adsorbent having a large surface area and properties based on silica, activated carbon (graphite carbon for MonoTrap TD) and Octadecyl functional group.

MonoTrap is a hybrid novel adsorbent that combines a large surface area and the properties of silica gel, activated carbon, and ODS. The large surface area of porous silica and the adsorbent effect due to the inclusion of activated carbon result in high collection efficiency. Therefore, high-sensitivity analysis can be performed in a short time. This time, we used MonoTrap DCC18 (with activated carbon) to perform simple enrichment analyses of the flavor components of moclene. Passive sampling was performed by placing more than one MonoTrap inside a sac-like tedra bag. (For dedicated tedra bags, please contact us separately.) The highly inert WAX-column InertCap Pure-WAX is the optimal column for fragrance components analyses. We recommend using this product in conjunction with ...

Adjustable range of chromatography conditions has been specified in [2.00 General theory of chromatography] which has been stipulated based on the contents harmonized and agreed upon by Japanese/U.S./European Trilateral Pharmacopoeia at the first supplemental public comment of Japanese Pharmacopoeia, 18th Edition, which was disclosed in September 2021. Based on this, the acceptable changeable range of conditions is widened, enabling easier requirement study. In this report, analysis was implemented by changing the column size within the range specified in [2.00 General theory of chromatography] for JP18 Purity test (5) of saccharin sodium hydrate. The change of analytical conditions is for the content to be applied from the first supplemental revision of JP18 and is not for the content ...

Kasugamycin is widely used as an agricultural fungicide. In this study, kasugamycin added to "brown rice", "orange", and "peanut" extracts was extracted and purified using a mixed-mode polymer solid-phase (InertSep MCX FF) with reference to a method complied with the notification test method of the Ministry of Health, Labor and Welfare. Analysed by LC / MS / MS.

Malachite Green (MG) is a blue-green basic pigment that is used as a remedy against aquatic fungal diseases, it is also used as a bactericidal agent for farmed fish. Current research suggests that it may be carcinogenic, therefore use in foods has been banned in the United States, EU, etc. The distribution and sale of foods in which malachite green is detected is banned in Japan. However, since on rare occasions violations of this ban are confirmed in imported foods, etc., tests are widely conducted by inspection organizations. In this study, malachite green and its biotransform Leucomalachite Green (LMG) were extracted from grilled eel extract and purified using a mixed-mode polymer solid phase (InertSep MCX FF, LMG) and then analyzed by LC / MS / MS with a test method complied with ...

When the pH of mobile phase is changed in the analysis of reverse phase mode on HPLC, the dissociation / non-dissociation state changes depending on the compound, so the retention time changes. Normally, the retention time is longer in non-dissociated state and shorter in dissociated state. This time, using Inertsil WP300 C18, we analyzed the basic compound saccharin and the acidic compound phthalic anhydride standard, and found that the elution order changed under acidic and neutral conditions. We also report that it was estimated that phthalic anhydride in the sample was partially changed to phthalic acid.
