‌Forensic Medicine and Chemical Engineering‌Used for substances such as acrylonitrileEPA Method 603 GC/MSanalyze

Key performance advantages‌

‌high thermal stability‌Adopting strengthened bonding technology significantly improves column life and high temperature tolerance, reducing baseline drift

‌Low loss characteristics‌Suitable for high-sensitivity mass spectrometry detection（GC/MS）Effectively reduce background noise

‌Excellent inter column reproducibility‌Each column undergoes strict factory testing and comes with‌COAQuality Certificate‌Support method validation and compliance declaration

‌High corrosion resistance‌Strong resistance to oxidative and acidic/alkaline samples, superior to traditional silicon-based stationary phases

Instructions for Use and Maintenance‌

‌Installation direction‌：Strictly follow the gas flow direction indicated on the chromatographic column（→）Installation, connect the injection port end to the injection spacer, and connect the detector endFIDorMSIonic source.

‌Aging treatment (mandatory)‌：New or unused columns need to undergo programmed temperature aging to remove residual solvents and volatiles:

1.Initial temperature:50°CMaintain it2 min

2.Heating rate:10°C/min

3.Termination temperature:‌250°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

‌Avoid pollution‌：

1.The sample needs to undergo ‌0.22 μmmembrane filtration‌To avoid particle blockage

2.High boiling point, strong acid, strong base or non-volatile substances need to pass through‌Solid phase extraction（SPE）Or liquid-liquid extraction‌Pre processing removal

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