Core advantages and technological features

‌Strong polarity retention ability‌Adopting bonding technology and strictly controllingC18The spacing between long chains ensures that‌High water phase even100%Water phase mobile phase‌Under certain conditions, it can still maintain stable retention and effectively avoid traditional practicesC18Column factor“Hydrophobic collapse”Resulting in retention failure issues.

‌High inertness and low adsorption‌Based on high-purity spherical silica gel (new type)ESSilicone matrix, with extremely low content of metal impurities on the surface and no significant adsorption of alkaline compounds, can be obtained‌Sharp and symmetrical peak shape‌Improve separation and quantitative accuracy.

‌widepHTolerance range‌: Can be inpH ‌1–10‌Stable operation within the range, suitable for strong acid or strong alkaline mobile phase systems, and applicable to a wider range of method development needs.

‌Excellent inter batch reproducibility‌Produced under strict quality control to ensure highly consistent retention times between different batches, suitable for method validation, long-term stability studies, and regulatory compliance projects.

Typical application scenarios

‌Pharmaceutical Analysis‌Used for detecting polar metabolites, impurities, or degradation products in drugs, such as amino acids, organic acids, nucleoside analogues, etc.

‌Biological sample analysis‌Suitable for the separation of polar small molecules in complex matrices such as plasma and urine, such as vitaminsBEthnicity, catecholamines, short chain fatty acids, etc.

‌Environment and Food Safety‌Can be used for residue detection of polar pollutants (such as pesticide metabolites, disinfection by-products) and food additives (such as sweeteners, preservatives) in water.

‌LC-MSPre processing for combined use‌Due to its stable performance under high aqueous conditions, it helps to improve the ionization efficiency and signal strength of mass spectrometry, making it particularly suitable for detection in positive ion mode.

This chromatographic column is used for developing complex samples‌Difficult to retain polar components‌The ideal choice for detection methods, widely used in fields such as pharmaceuticals, biological analysis, environmental monitoring, and food safety.
