"Ion Pair Reagent" is a reagent for HPLC. In chromatographic analysis of samples containing ionic compounds, issues may arise with solute retention and peak shape. In such cases, it is known that adding an ion pair reagent to the mobile phase can improve separation, and it is particularly useful in reverse phase chromatography. When this reagent is added to the mobile phase, ions of opposite charges attract each other to form neutral ion pairs, which suppresses the dissociation of the sample in the mobile phase. Additionally, since the ion pair reagents are bonded with various alkyl groups, the formed ion pairs become more lipophilic, resulting in increased retention on ODS packing materials. We offer a lineup for both basic and acidic samples. If you require more guarantee items for use in pharmaceutical testing, we can provide a quote. Please feel free to consult us. In addition, we handle other HPLC reagents: ◇ Solvent for High-Performance Liquid Chromatography HLC-SOL ◇ For LC/MS ◇ For pharmaceutical testing ◇ Pre-prepared mobile phases (custom orders available) …etc. For more details, please download the catalog or feel free to contact us.

The residual solvent test measures the amount of organic solvents present in pharmaceuticals using methods such as gas chromatography, confirming that organic solvents do not exceed the limit values in the pharmaceuticals. Most commercially available general reagents have not had low boiling point impurities removed, making them unusable as the impurity peaks from the reagents overlap with the peaks of the substances being measured on the GC chart. This product reduces the content of low boiling point compounds such as methanol and guarantees quality through a unique residual solvent compatibility test. The expiration date is displayed on the label, and a certificate of analysis can also be issued. Additionally, we offer single-use reagents packaged in 100mL. Please make use of these for recording and managing reagents.
