This product overcomes the challenges of conventional silver nitrate-impregnated silica gel, offering high safety and distinctive separation capabilities, with potential applications beyond the food sector. 【Features】 ■ Separation of cis/trans isomers Generally, the cis isomer has a higher stability of the complex formed with Ag+ than the trans isomer, resulting in the cis isomer being retained more strongly while the trans isomer elutes first. ■ Separation of positional isomers Regardless of the number of carbon atoms, the further the double bond is from the carbonyl carbon, the faster it elutes. Additionally, in the separation of aromatic compounds, they elute in the order of o-isomer, m-isomer, and p-isomer. ■ Separation of fatty acids with different carbon chain lengths Fatty acids with a higher number of carbon atoms elute faster. Moreover, those with more double bonds are retained more strongly. ■ Separation of compounds with multiple double bonds Non-conjugated double bonds are retained more strongly than conjugated double bonds. Furthermore, the closer the double bonds are to each other, the faster they elute. For more details, please download the catalog or feel free to contact us.

Please select the most suitable gel for various separation and purification processes. 【Features】 ■ pH of Silica Gel Pure silica gel (SiO2) is widely known to exhibit weak acidity due to its surface structure, but depending on the properties of the sample, such as unstable substances under acidic conditions, pure silica gel may not be suitable for separation. We provide pH-adjusted products (Silica Gel 60N) to be used for the separation of a wide range of compounds. ■ Chemically Modified Silica Gel We offer types modified with aminopropyl groups and octadecylsilyl groups. ■ Ultra High Purity Silica Gel This silica gel has ultra-high purity and significantly reduces the adhesion of fine powder and metal impurities compared to existing sphere-shaped silica gel series.

The quantification of the pharmaceutical ingredient hypromellose is performed using gas chromatography with standard solutions of isopropyl iodide and iodomethane. Additionally, for the quantification of ethyl cellulose listed in the 17th Revised Edition of the Japanese Pharmacopoeia Second Supplement (June 2019), standard solutions with added ethyl iodide are used. Both are quantification reagents that comply with the purity tests and content standards specified in the Japanese Pharmacopoeia. In addition to this product, we also offer color reagents for thin-layer chromatography analysis, as well as reagents and test solutions for purified sodium hyaluronate. For more details, please refer to the catalog below.

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.

"Premix products" are pre-prepared elution liquids that mix high-purity formic acid or trifluoroacetic acid for LC/MS grade. This minimizes the hassle of preparation and the issues related to contamination in the working environment. 【Product Lineup】 0.1% (v/v) Formic Acid - Acetonitrile 0.1% (v/v) Formic Acid - Distilled Water 0.1% (v/v) Trifluoroacetic Acid - Acetonitrile 0.1% (v/v) Trifluoroacetic Acid - Distilled Water We can also prepare solutions in the desired composition ratio upon request. We can accommodate salt dissolution and scale-up. 【Basic Specifications】 Solvent Type: Generally prepared from HPLC and LC/MS standard products, but we also accept inquiries regarding buffer solutions. Container: Glass container Main Applications: Elution liquids for HPLC, LC/MS, pretreatment, etc. Standard Items: Primarily density only (as a guideline for composition ratio). We also accept inquiries regarding specifications other than density (metal impurities, UV guarantees, etc.). 【Features】 ■ Reduced burden of reagent management Exclusion from toxic and hazardous substances, lowering the hazardous material classification. ■ Reduction of waste reagents ■ Improved reproducibility For more details, please download the catalog or feel free to contact us.

In the general tests for pharmaceuticals described in the Japanese Pharmacopoeia (JP), a high-grade quality as specified by JIS standards is often required for analytical reagents. On the other hand, representative pharmacopoeias from overseas, such as the United States Pharmacopeia (USP) and the European Pharmacopoeia (EP), also establish their own quality standards for analytical reagents, similar to JP. This product guarantees a quality that complies not only with the special grade standards but also with the reagent standards set by USP and EP. It is a product that is frequently used as an analytical reagent and is suitable for pharmaceutical tests specified by JP, USP, and EP.

Our "Color Comparison Solution" is prepared by mixing solutions of several inorganic salts, known as "Color Comparison Concentrate," in a specific ratio to achieve the designated color. We have adopted a 100mL low-capacity type suitable for small-scale solution preparation, which eliminates the possibility of contamination. Additionally, the preparation is in accordance with the Japanese Pharmacopoeia, and the label displays the expiration date. The sulfuric acid suitable for the color reaction test is already prepared at the required concentration. This product is diluted to comply with the concentration ranges of the Japanese Pharmacopoeia, United States Pharmacopeia, and JIS (K 0072).
