Syringes must ensure a tight and secure fit in the injection port and withstand repeated injection cycles without bending or breaking.
- Can withstand repeatable injections
- Variety of fixed and removable needles
- Inspected to ensure accuracy and performance
Autosampler syringes are available in 0,5, 5 and 50 μl capacities. For routine analyses, the metal plunger in barrel with PTFE-tipped seal is the standard syringe with each GC instrument.
Ultra-micro volume syringes are recommended for liquid sample injections of less than 5 μl for gas chromatography.
Point style 2: This is a general-purpose point style designed for septum penetration in all chromatographic techniques. The needle has a 22° bevel to minimise coring and needle plugging.
Point style 3: Needle has a 90° bevel. Point style is recommended when the syringe is used for accurate pipetting of liquids. Excellent for mixing standards of very small volume.
