Syringe Selection Guide
If a syringe is being used by hand, a manual syringe should be selected. If a syringe is installed in an AOC autosampler, then choose the
appropriate syringe and volume to suit your instrument and application.
Plunger-in-needle style. The plunger goes into the needle tip to eliminate dead volume. Ideal for highly precise analysis of micro-volume samples.
This type of microsyringe has an extended barrel (120 mm long) to prevent the plunger from bending.
A gas seal gland is provided at the rear of the barrel to ensure pressure resistance of 15 kgf/cm2 (100 μL or less in capacity) or 12 kgf/cm2 (250 μL or larger in capacity).
These syringes use a titanium alloy plunger, which is highly exible and corrosion resistant. The high exibility of the plunger ensures stable injection of samples as small as 5 μL. The needle is 0.41 mm in tip diameter, which is suitable for on-column injection into a capillary column.
A guide bar is installed parallel to the plunger, which prevents the plunger from bending. A stopper is also provided to allow a preset amount of sample to be injected accurately without reading the scale in each run.
Micro extraction by packed sorbent (MEPS) is a tool that provides a new way to pretreat samples. By using less packing material (about 3 mg), it can reduce the amount of solvent used down to the milliliter level.
Because MEPS solid phase cartridges can be reused multiple times, the method not only improves the ef ciency of sample pretreatment and concentration adjustment processes, but also helps reduce costs.
MEPS is a micro-solid phase extraction (μSPE) method that combines micro-solid phase cartridges with high-quality microsyringes.
MEPS solid phase cartridges (MEPS BIN) reduce the quantity of solid phase packing material used from the conventional mL-level to the μL-level. C2, C8, C18, silica, and other MEPS solid phases can be used.
