Syringes for Agilent GC Autosamplers

Blue Line Syringes:

• Blue line syringes precisely match with your autosampler’s stroking mechanism for more accurate volume delivery
• The smooth needle of the blue line syringes reduces septum coring and keeps your system working at its full potential
• Blue line syringes are available in a choice of PTFE-tipped or metal fitted plunger to meet your application needs
• Blue line syringes are delivered in easy-open, environmentally friendly packaging

Gold Standard Syringes:

• Lot numbers are printed directly on the barrel of gold standard syringes, with a corresponding Certificate of Conformance ensuring certified performance to all specifications
• The gold protective cap on the fused needle of the gold standard syringes, prevents the glass syringe barrel from chipping as it is pressed against the inlet
• Black ink and a gold illuminating backing strip, enables effortless viewing of the volume scale of gold standard syringes and is easily discernible from imitators
• Environmentally friendly packaging, with an improved design that reduces waste
• Gold standard syringes are individually sealed, for contaminant-free use right out of the box

Gold Standard High Flow Syringes:

• Similar to the standard 23-26s tapered, fixed needle microliter & gas-tight syringe with a ≈35% wider needle ID to accommodate the most challenging sample matrices
• Tapered needle with the durability of a 23s-gauge needle, and versatility of a 26s-gauge needle
• Reduced internal pressure and reduced risk of cavitation during automated, high-speed injection
• Compatible with the standard 7693, 7650 XL ALS, and 7696 GC Workbench
• Fitted stainless steel & PTFE-tipped gas tight plunger options
• Comparable performance and injection-injection repeatability to conventional offerings
• Suitable for 1.0uL – 8.0uL liquid and gas phase injections

PTFE-Tipped Syringes have a precision-machined plunger tip that forms a tight seal and enables the tip to wipe the barrel’s interior free of sample during operation. This feature is particularly useful for viscous or heterogeneous samples, because it reduces deposits that can cause the plunger to freeze. Replacement plunger assemblies are available for most PTFE-tipped syringes.

Fitted Plunger Syringes feature a stainless steel plunger that is meticulously hand-fitted to its matching glass barrel, creating a liquid-tight seal. These syringes are ideal for homogenous samples that are not prone to precipitation or bonding with glass. Note: plungers cannot be interchanged or replaced if damaged.

Needle Gauge is the thickness of the needle. The gauge depends on the injector. When selecting a needle gauge, it is important to keep in mind the volume of the syringe and the dead volume of the needle.

• Tapered Dual Gauge 23-26 or 23s-26s (0.64 - 0.47 mm) - Durability of a 23 gauge and versatility of a 26 gauge for split/splitless and on-column injection
• Single Gauge 23 or 23s (0.64 mm) - Suitable for Merlin Microseal septa, packed column injector ports and split/splitless injector ports
• Single Gauge 26 or 26s (0.47 mm) - Suitable for packed column injector ports and split/splitless injector port

Needles with an 's' following the gauge are more durable, with a thicker needle wall and smaller id bore.

Needle Terminations are available in fixed or removable, with various tip styles:

• Fixed (cemented) – Economical, reproducible injections for autosamplers
• Removable needle – One syringe fixed – many methods, simplicity of fixed needle, but needle can be replaced if damaged or clogged

Needle Tip Design

• Cone Tip (HP Tip, Point Style AS) - Proprietary design required for Agilent autosamplers for optimal performance and reliability by reducing septum coring
• Bevel Tip (Point Style 2) - General purpose; excellent choice for transferring liquids from ampoules or vials. For manual GC injections, a beveled tip is preferred for optimum septum penetration and to prevent septum coring.
• Side Hole (Point Style 5) - Recommended for thin gauged septa or large volume injections
