Abstract:
Methods and apparatus are disclosed for detecting one or more species in a sample, wherein laser probe light is frequency swept across at least one infra red absorption spectrum feature of each of the species. A path from the probe light source to a single detector element may be switched between at least one sample absorption cell or volume and one or more reference cells or volumes.
