Gas Bag Sampler (GBS)
Automatic Gas Sampler
Sample transfer is carried out via a multi-position valve. Each gas sampling inlet is equipped with an in-line filter to avoid multi-position valve blocking. Connection to the GC can be made by means of 1/16” SS tube.
The GBS is controlled via a special JAS Control Software.
Available Models
• GBS-8
• GBS-10
As standard models for 8 or 10 bags/ balloons are available, each has an additional purge and vent port. On request the gas sampler can also be supplied for more than 10 bags.
Optional:
• Inert version
• JAS GICU (Gas Injection Control Unit) to set the pressure for reproducible results
Features
• Can handle bags/balloons of 2-3 bar
• Flow paths can be purged
• Includes pump for samples with atmospheric pressure
• Intuitive JAS Control Software
• Bags can be selected randomly
• Display shows current port position
• Minimum waiting time between runs (sample loops can be purged while run is still in progress)
• Existing GC methods do not need to be changed
• In one sequence pressurized samples and samples with atmospheric pressure can be processed
• For Agilent and third-party GCs (control via start-stop/remote cable)

At atmospheric pressure or slight low pressure respectively slight overpressure a pump can suck in the sample. The pump capacity is manually adjustable.
The GBS front panel has a display for indicating the current position.
