FAQs – Syringe & Needle Selection Guide and Best Practices
Q1: How do I choose the right syringe volume for my application?
Select a syringe that closely matches your sample injection volume. For example, use a 10 µL syringe for 5–10 µL injections to maximize accuracy. Avoid using oversized syringes for small volume injections, as it may affect reproducibility.
Q2: What needle tip types are available, and how do I choose?
Common Agilent needle tip styles include:
- Bevel Tip: Standard for manual injections
- Cone Tip: Ideal for autosamplers with septum piercing
- Blunt Tip: Used with valve-based systems
- Side Port Tip: For specialized sampling techniques
Choose the tip type based on your instrument’s requirements and sample properties.
Q3: How can I avoid carryover or contamination?
- Use syringes with chemically inert materials like PTFE plungers or glass barrels
- Rinse syringes thoroughly with solvent between samples
- Consider using gas-tight syringes with fixed needles for sensitive analyses
