We discuss the modification of an old method of connecting two capillary columns in a confluent configuration which elegantly allows introduction of make‐up gas at a controlled flow rate when the effluent is split for electroantennographic detection experiments, and allows for easy switching of the stationary phase between successive GC runs. Being able to run samples on different phases is extremely beneficial, both for optimal resolution of active compounds and for compound identification. This method warrants greater consideration by GC‐EAD practitioners.
