Syringe Characteristics and Recommended Uses
Syringe Advantage Limitations Recommended Use
10 µL, PTFE-tipped
• Less plunger binding than fitted
plunger
• Replaceable plunger for reduced
repair cost
• Tight seal between plunger and barrel
• More expensive than fitted plunger
• PTFE-tipped syringes not available
in 5 µL size
• High sample throughput
• Samples in polar solvents
• Dirty samples
• Gases and volatile samples
• Reactive samples
10 µL, fitted plunger
• Most economical
• Most reliable fitted plunger syringe
• Less bending
• Better for high viscosity samples
• Most accurate only for 1 µL and
larger injections
• Plunger not replaceable
• General purpose syringe
• Clean samples
• Routine analysis
5 µL, fitted plunger
• Most accurate for 1 µL injection
• No hardware modification needed for
0.5 µL
• Thinnest plunger, can bend more
easily
• Not ideal for higher viscosity
samples
• Plunger not replaceable
• 1 µL injections
• Clean samples
• Routine analysis
