Frequently Asked Questions
1. Why is the internal diameter (ID) of a GC liner important?
The liner ID, such as the 4mm or 1mm PTV models from Trajan, dictates the internal volume available for sample vaporization, which must match your injection volume and technique.
2. When should I use graphite ferrules instead of Vespel?
Graphite ferrules (like the Trajan OGF16 series) are ideal for high-temperature applications as they are soft and provide a reusable seal, whereas Vespel is typically used for MS applications requiring higher vacuum integrity.
3. What are the benefits of the Trajan Microliter Syringe?
Trajan syringes are designed with tight tolerances and plunger-to-barrel fits that prevent sample carryover and ensure high-precision volume delivery.
4. How often should I replace my GC liners and ferrules?
Liners should be replaced regularly to prevent peak ghosting caused by non-volatile residues, while ferrules should be inspected and replaced whenever a column is re-installed to prevent leaks.
