Chromatography Columns

Specially designed for clinical mass spectrometry

High-performance, compliant chromatography columns

  • The Core of Separation — Chromatography Columns

    • In the routine analysis of liquid chromatography–tandem mass spectrometry (LC–MS/MS), the analytes must first be separated by the chromatograph before entering the mass spectrometry system for analysis. As the “heart” of the chromatograph, chromatography columns with high column efficiency, good selectivity, and fast analysis speed help clinical laboratories obtain more accurate test results!
    The National Medical Products Administration (NMPA) explicitly requires in the latest Medical Device Classification Catalog that chromatography columns used for separating analytes in human samples be independently regulated as Class II medical devices.

    2. Wide Range of Types – Covers common clinical test items such as vitamin detection, steroid hormone analysis, and therapeutic drug monitoring.
    3. High Performance – Enables better peak shape and higher separation efficiency.
    4. Excellent Compatibility – Compatible with commonly used clinical mass spectrometers; suitable for HPLC, UHPLC, and UPLC analysis.
    5. Superior User Experience – Comprehensive operating procedures and complete after-sales support.

  • Application Example 1 — Water-Soluble Vitamin Detection

    Mobile phase A: Ammonium acetate aqueous solution
    Mobile phase B: Methanol
    Column: N-WSV
    Column temperature: 40 °C
    Injection volume: 5 μL

    Even in complex matrices, using standard mobile phase conditions, various water-soluble vitamins can achieve symmetrical peak shapes on the N-WSV chromatography column, making it suitable for LC–MS/MS analysis!

    • A: Shanghai Ruikang Catecholamine Dedicated Chromatography Column   B&C: Other non-dedicated types of chromatography columns

    Compared with other column types, the dedicated catecholamine column produces more ideal peak shapes — without fronting or tailing peaks — ensuring higher accuracy in clinical quantification!
