1. A system, comprising:
a turbine vane of a turbine stage configured to mount along a combustion gas path of a gas turbine; and
a multi-fluid injector coupled to the turbine vane, wherein the multi-fluid injector comprises a fuel port configured to inject a fuel, an oxidant port configured to inject an oxidant, and a barrier fluid port configured to inject a barrier fluid between the fuel and the oxidant, wherein the barrier fluid is configured to delay mixing between the fuel and the oxidant.
