GC Analysis & Headspace Analysis: Choose the Right Vial
Choosing the correct vial is the first step for accurate & stable GC detection! 🧪
Many lab analysts confuse 2mL standard vials and 20mL crimp headspace vials in daily GC work. Here is a clear & professional selection guide ✅
🔹 2mL Standard Vial | For Direct GC Injection
✅ Ideal for semi-volatile & high-boiling compounds
✅ Suitable for clean, clarified liquid & solvent extracts
✅ Requires filtration & dilution pretreatment
🔹 20mL Crimp Headspace Vial | For Headspace GC Analysis
✅ Perfect for VOCs, solvent residues & volatile impurities
✅ Compatible with complex matrices: solid, viscous, high-salt & oily samples
✅ Only v***r enters the instrument, greatly reducing GC system contamination
✅ Minimal solvent usage, simpler pretreatment
Core Takeaway 💡
Clean samples & semi-volatile analysis → 2mL Vials
Volatile residues & complex matrix analysis → 20mL Headspace Vials
Proper vial selection improves data accuracy and extends instrument service life! 🔬
