GAS-TAP is a laboratory technique used to extract and analyze volatile organic compounds from liquid and solid samples. It involves introducing a gaseous solvent onto the sample surface in a sealed vessel, which absorbs the VOCs that subsequently evaporate into the headspace of the vessel. The headspace is then sampled using a gas chromatograph to detect the individual VOCs. It is highly sensitive and selective, with detection limits in the parts per billion to parts per trillion range.

Key Technical Specifications

• Material: The body of the gas tap is typically made of brass or stainless steel, with a chrome-plated finish for corrosion resistance.
• Valve type: The valve is a quarter-turn ball valve, providing precise and quick control of gas flow.
• Connection type: The tap is designed to connect to a standard 8 mm gas hose.
• Operating temperature range: The tap can operate in temperatures ranging from -10°C to 120°C.
• Pressure rating: The tap can handle a maximum pressure of 10 bar.
• Flow rate: The maximum flow rate for GAS-TAP 1way depends on the gas being used and the pressure at which it is being delivered. The tap is designed to provide precise control over the flow rate, with a quarter-turn of the valve allowing for easy adjustment.
• Safety features: GAS-TAP 1way includes a locking mechanism to prevent accidental opening or closing of the valve. It also has a visual indicator to show when the valve is in the open or closed position.
• Size and weight: GAS-TAP 1way typically measures around 70 mm in height and 45 mm in width, and weighs approximately 200 grams.
