Disclosed herein are detectable refrigerant compositions, comprising from about 0.001 to about 5 weight percent tracer compositions, which are useful to identify leaking in a vapor compression refrigeration and/or air conditioning system. The presence of the tracers make the refrigerant compositions detectable by chemo/electro-active array, corona discharge, heated diode, electrochemical, photoionization, infrared, ultrasonic and electron capture detectors. |
