Merlin MicroShot
InstructIon Manual
The Merlin MicroShot Injector delivers quick and reproducible
manual syringe injections for gas chromatography.
Key coMPonents
Figure 1 shows the components of the
Merlin MicroShot Injector and will be
referred to throughout this instruction manual.
CauTIon: Pumping a dry syringe can
reduce the syringe life and compromise
injector performance. Always supply
solvent to the needle tip when moving
the syringe plunger.
selectIng a syrInge
The MicroShot Injector does not come with a
syringe installed. These can be purchased from your
distribution partner.
Figure 2 shows the syringe compatibility requirements
including plunger end detail, which is important for proper
function. A 10 µL syringe will give the nominal injected volume
indicated for that MicroShot Injector and a 5 µL syringe will
give half that volume. Removable or fixed needles, 23 or 26
gauge needles can all be used with the MicroShot Injector.
