Confirmation Mode
Confirmation Mode Technique injects the same sample into two injectors to confirm the analysis.
The GC is started on the first injection.

Liquid mode
Air Gap
An air gap is a “cushion” which is sometimes used when using Internal Standards. The gap can
be between the Internal Standard and the sample (“post” mode), or may be after both the
Internal Standard and sample (mode “double”).
Dual injection modes (Confirmation Mode, High throughput Mode)
High throughput mode injects different samples into two separate injection ports.
Confirmation Mode Technique injects the same sample into two injectors to confirm the analysis.
For both modes the GC is started on the first injection.
Internal Standard
This is an analytical technique that injects a sample and a reference standard at the same time.
The reference is drawn first into the syringe and the sample afterwards. They are injected
together.
SyringeID
SyringeID is an automatic syringe recognition system, available if GLP pack has been
purchased (1.7.2 “Options“). This system is based on RFID tags and it is able to identify syringes in
an univocal way.
The RFID tag contains information regarding the syringe serial number and part number, the
syringe volume and the number of plunger strokes performed.
Enabling the “SyringeID” system, errors during syringe installation are avoided because the
syringe serial number and volume are automatically read. Furthermore the system keeps track of
the syringe “wear and tear” by the “Plunger stroke counter” that it is automatically updated after
each run.
The syringe information are loaded in a RFID tag included in the black adapter mounted on the
syringe for the syringeID system (see paragraph 1 2 . 2 . 1 “ Syringes“). Every adapter must be
associated to a syringe only in order to maintain the info regarding the syringe always correct
and updated. Do not remove the syringe from its black adapter.
