Enabling stable flow control in the ml range, a new proportional 16 mm Fasprop valve from IMI Precision Engineering – with branches in the US, Mexico and Brazil – has been launched to increase gas chromatography (GC) repeatability and to improve the detection limit of the instruments.
Fasprop, part of the IMI Fas product range, offers a highly compact proportional valve design, as well as an extremely small orifice – measuring just 0.05 mm. Able to precisely control low flow rates in the ml range up to 174 psi/12 bar, Fasprop regulates flow and pressure supply to detectors, which improves stability and sensitivity. In packed and capillary GC columns, the valve also prevents the peak retention time shift caused by poor flow control.
Utilizing well established flat plunger/spring technology commonly used in 16 mm valves for medical devices in gas dosing applications, these reliable valves offer proven performance over a 100 million cycle lifespan.
