Abstract:
1. A dual matrix LA-ICP spectroscopic analysis system specifically adapted for performing a method of dual matrix LA-ICP analysis comprised of: at least one ablation chamber housing which substantially encloses an ablation chamber; an inductively coupled plasma ionization chamber fluidly connected to said ablation chamber; wherein said ablation chamber housing is adapted for passage of a laser beam though the inner and outer surfaces of said ablation chamber housing; wherein said ablation chamber housing includes at least two apertures to enable the entry and exit of an inert carrier gas into said inductively coupled plasma ionization chamber fluidly connected with said ablation chamber housing; a revolvable sample receptacle adapted to secure a quantity of ablative material, wherein revolvable sample receptacle includes a designated area for a quantity of a sample under test and a designated area for a standard sample; a motor operatively coupled to said revolvable sample receptacle and able to cause said sample receptacle to spin around an axis to produce a spinning sample under test; and wherein a laser component which produces a laser beam, wherein said laser beam is directed at said spinning sample under test and wherein said laser can be configured to produce a static ablation trajectory that is in contact with said ablative material held within said spinning sample chamber for an ablation period.
