The Non‐Methane Hydrocarbon Intercomparison Experiment (NOMHICE) is described. This experiment has been designed to evaluate analytical techniques currently being used by scientists throughout the world to measure ambient atmospheric hydrocarbon concentrations. NOMHICE consists of a series of planned experiments designed to identify existing problems in participating scientist's laboratories and to correct them. The various experimental steps (or phases) have been scheduled in order of increasing complexity so that problems can be addressed as they arise. Results are presented for the initial phases of this program. Phase 1 involved the circulation of a 2 component gravimetrically prepared standard to 40 laboratories throughout the world. Participants were asked to quantify but not identify the components. Phase 2 involved the circulation of a more complex 16 component gravimetrically prepared mixture to 32 participants. Participants were asked to identify and quantify the components. Further tasks are described which will be carried out in the future.
