Typical application areas‌

This chromatographic column is particularly suitable for the following high-resolution analysis scenarios:

‌pharmaceutical industry‌Based on:ICH Q3CGuide testing‌residual solvent‌(such as acetonitrile), used for‌Mass spectrometry analysis of oxygen-containing compounds and amine impurities‌

‌environmental monitoring‌: Analysis‌pesticide residue‌The‌PCBMixed standard‌、‌Polychlorinated biphenyls‌Persistent organic pollutants（POPs）

‌food safety‌: Testing in food‌Fragrance and flavor‌、‌additive‌and‌Illegal additives‌

‌Forensic Medicine and Chemical Engineering‌: Used for‌Confirmatory analysis‌Especially suitable for the separation of compounds with small polarity differences

Key performance advantages‌

‌Consistency between high columns‌Strictly test retention time, theoretical number of trays, and column loss rate for each batch, supporting method transfer and validation

‌Low column loss‌Exclusive bonding process significantly reduces baseline drift at high temperatures, improvingGC/MSsignal-to-noise ratio

‌Excellent inertness‌Show good peak shape and reduce tailing for active compounds such as alcohols, acids, and amines

‌long-term stability‌Can be used continuously for hundreds of needles or more within the recommended temperature range, with a long lifespan

Precautions for use and maintenance‌

‌Installation direction‌：Be sure to follow the gas flow arrow marked on the column body（→）Installation, connect the injection port end to the gasket for blowing, and connect the detector endFIDorMSIonic source.

‌Aging treatment (mandatory)‌：New or unused columns require programmed temperature aging:

1.Initial temperature:50°CMaintain it2 min

2.Heating rate:10°C/min

3.Termination temperature:‌270°C‌Maintain it‌30–60 min‌

4.Carrier gas:‌Helium or nitrogen, flow rate1.0 mL/min ‌Ensure that there is a carrier gas passing through the entire process

During the aging process, the baseline may briefly increase, which is a normal phenomenon. It can be used after the baseline stabilizes

‌Avoid pollution：‌

1.The sample must go through ‌0.22 μmmembrane filtration‌

2.Samples containing particles, strong acids, strong bases, or high boiling point substances require pre-treatment (such as...)SPELiquid liquid extraction

3.The injection port gasket should be replaced regularly to prevent debris from entering the chromatographic column

‌Column head cutting and regeneration‌：If there is peak tailing, retention time drift, or column pressure increase, it can be cut off from the injection port end ‌10–20 cm‌Use after re aging

‌storage method：‌

1.After use, seal both ends with sealing caps,‌Store in a dry and cool place‌Avoid direct sunlight or severe vibrations

2.When not in use for a long time, it is recommended to rinse with isopropanol and store it dry
