Glycerin for gas chromatography

Seventeenth Revision of the Japanese Pharmacopoeia Regulations "Glycerin for Gas Chromatography"

Glycerin is used in various applications such as solvents, ointment bases, and moisturizing and lubricating agents in pharmaceuticals. According to the Japanese Pharmacopoeia, the glycerin purity test states, "Use the special grade standard (however, when conducting the purity test for 'concentrated glycerin,' no peaks should be observed for the retention times of ethylene glycol and diethylene glycol)." Our company offers reagents that comply with the "Glycerin Gas Chromatography" standards set forth in the seventeenth revision of the Japanese Pharmacopoeia. We encourage you to consider our reagents for the purity test of pharmacopoeial glycerin.

Environmental regulation "RoHS2.0 related reagents" adds regulated substances to the special grade standards!

In response to the revised RoHS directive, we have released a RoHS2 compliant standard that adds four phthalate ester substances! The guaranteed values are below 1/10 to 1/100 of the regulatory values.

The RoHS Directive is a directive from the European Union (EU) regarding the restriction of the use of certain hazardous substances in electrical and electronic equipment. Until now, we have been releasing standards compliant with RoHS, but with the revised RoHS Directive (RoHS 2.0) that came into effect on July 22, 2019, the number of restricted substances has increased from 6 to 10. As a result of this directive, we have released RoHS 2 compliant standards that include 4 additional phthalate esters. [List of regulated substances under the revised RoHS Directive] Cadmium Lead Hexavalent chromium Mercury Polybrominated diphenyl ethers Polybrominated diphenyl Di-2-ethylhexyl phthalate Dibutyl phthalate Butyl benzyl phthalate Diisobutyl phthalate Similar to the previous RoHS compliant standards, we have added the 10 regulated substances of RoHS 2.0 as standard items in the special grade standards. Additionally, the guaranteed values are set to be less than 1/10 to 1/100 of the regulatory values. In addition to mixed standard solutions and standard materials for environmental analysis, we also handle JCSS compliant standard solutions and certified standard materials. Please choose according to your analysis needs. For more details, please download the catalog or feel free to contact us.

Create molecules that color sugar.

Keywords: analytical reagents, molecular recognition, supramolecular chemistry, metal complexes, nanoparticles, luminescence, dyes

Various types of sugars exist within living organisms. Each of these plays an essential role in maintaining life and is constantly circulating within the body. Therefore, an imbalance of sugars in the body directly leads to serious diseases that threaten us today (e.g., diabetes). In other words, the development of technology to measure sugar levels is crucial for the early detection of bodily disorders. To develop such technology, I am designing "analytical reagents," which are molecules that glow when they bind to sugars. In my research, I am developing analytical reagents with a simple structure and excellent detection capabilities by using various frameworks (organic dyes, metal complexes, supramolecular complexes, nanoparticles, etc.) as a foundation (Figure 1). So far, I have successfully developed a supramolecular complex-type analytical reagent that specifically fluoresces for D-glucose (blood sugar) among the numerous sugars (Figure 2). I believe that this technology will lead to the development of a diagnostic system for the early detection of diabetes.
