Abstract A new, simple, inexpensive continuous flow programming technique for process capillary gas chromatography is described. Using a commercially available electronic mass flow controller and an interface device built in this laboratory, linear flow-rate programs of up to 40 ml/min were produced through a 50-m wide-bore capillary column under integrator control. Analysis time for a mixture of alkanes ranging in boiling point from 36 to 200°C separated at 75°C on a 15-m column was reduced from 18 to 5 min with flow programming. Advantages of the flow programming technique include shorter cycle times compared to temperature programming and enhanced sensitivity for late eluting components.
