Supplies for Agilent GCs: Inlet
Merlin Microseal Septa for Agilent GCs
• Allow operation from 3 to 100 psi (general-purpose Microseal septa)
or 1 to 45 psi (low-pressure Microseal septa).
• 400 °C max injection port temperature.
The advantages of the Merlin Microseal septum include elimination of septum coring;
longer life; and consistent, low needle-insertion force. The Microseal septum incor-
porates two separate sealing mechanisms. These sliding seals eliminate septum coring
and the resulting accumulation of septum crumbs in the injection port liner.
The Microseal septum uses a 23-gauge (0.63 mm, 0.025") needle or probe with a blunt,
truncated conical tip. Since the syringe plunger end details are determined by manual
or autosampler compatibility, often a removable needle syringe is an effective way to
match both of these requirements. No adapter is required for the Agilent inlet. Instal-
lation is simple, requiring no modification of the injection port.
Note: Merlin Microseal septa require a 23-gauge (0.63 mm, 0.025") needle or probe with a blunt, truncated conical tip.
Compatible syringes and replacement needles are available at
*Syringe not included. Requires Agilent-style (ball-end plunger) autosampler syringe.
Merlin MicroShot™ Injector
• NIST traceability assures accurate injections.
• Fixed volume reduces sampling error.
• Saves time—no need to transfer to autosampler vials.
• Prevents bent syringe plungers.
• Five injection volumes available.*
Increase the accuracy and reproducibility of manual injections with the Merlin Micro-
Shot™ injector. This new injector is calibrated to NIST reference standards to assure ac-
curate and traceable displacement. Precise repeated injections of the preset volume can
be made using a standard autosampler syringe with less variation than when injecting
by hand. The trigger mechanism provides rapid sample delivery, which reduces needle
residence time in the injection port and minimizes potential sample discrimination.
The Merlin MicroShot™ injector allows convenient sampling from a wide variety of
containers, so you can save time by eliminating the need to transfer aliquots into au-
tosampler vials. The design of this unit also includes a plunger support, which protects
the syringe plunger and prevents it from bending.
Fits Agilent-style (ball-end plunger) autosampler syringes with either fixed or remov-
able, 23- or 26-gauge needles.
