HPLC column for optical isomer separation
Optical isomers present in various bioactive substances (such as pharmaceuticals, pesticides, and fragrances) that are deeply related to our daily lives are known to exhibit significantly different biological activities between isomers, increasing the necessity for the analysis and separation of optical isomers. The "SUMICHIRAL OA series" HPLC columns for the separation of optical isomers are gaining attention in fields such as pharmaceuticals and pesticides.
Ultra-low pressure HPLC column achieving the highest standard of low pressure with a particle size of 3 μm.
This is a general-purpose column made from high-purity silica gel manufactured based on the technology our company has cultivated over many years. The SUMIPAX ODS series offers a wide range of high-performance columns, each with different characteristics. We believe that by selecting the optimal column from a variety of options with differing specificities, we can meet all analytical needs.
Separation of positional isomers using reverse phase and HILIC analysis! An additional step to add to C18 and HILIC columns.
The "F5 (PFP) HPLC/UHPLC column" for metabolomics is a reversed-phase column with selectivity different from C18. By incorporating it as a second or third choice column in reversed-phase systems, the range of substances for LC analysis is broadened. Four retention mechanisms—hydrogen bonding, dipole-dipole interactions, π-π interactions, and hydrophobic interactions—complexly influence each other to exhibit unique retention characteristics and stereoselectivity. 【Features】 ■ Retains highly polar basic compounds without ion-pair reagents ■ 100% water mobile phase is usable ■ Suitable for LC/MS due to retention at high organic solvent concentrations ■ Supports both analysis and fractionation *For more details, please refer to the PDF document or feel free to contact us.

The use of solid-phase microextraction (SPME)! An excellent analytical method that replaces traditional headspace analysis.
This document presents the results of residual solvent analysis using both the conventional direct injection method and the economical solvent-free high-speed SPME method. SPME is a technique that eliminates the costs and hazards associated with the use of organic solvents, allowing for the high-precision extraction of analytes over a wide concentration range under consistent sampling conditions. We compare three columns equivalent to those described in both EP and USP for the analysis of 60 out of 61 solvents (those detectable by GC/FID), and provide descriptions of these columns. We encourage you to read it. [Included Items (Excerpt)] ■ Column names from USP and EP and their equivalents from Supelco ■ Interactions between the stationary phase and the analyte ■ Interactions between the stationary phase and residual solvents ■ Retention times and elution order of Class I residual solvents on the EquityTM-5, SUPELCOWAXTM 10, and OVI-G43 columns ■ Retention times and elution order of Class II residual solvents on the EquityTM-5, SUPELCOWAXTM 10, and OVI-G43 columns *For more details, please refer to the PDF document or feel free to contact us.
Achieved rapid analysis within 5 minutes! Demonstrated excellent separation capability for methyl group positional isomer PAHs.
