A modular inductively coupled plasma torch assembly is described. A rear connector unit is positioned and detachably held at a rear end of a tubular plasma chamber to provide a flow of material into it. Detachable connector units are positioned on opposite ends of a tubular jacket, and hold the tubular plasma chamber concentrically within the tubular jacket so as to define an annular chamber between the two tubes. An inductor coil is disposed concentrically around the tubular jacket and energized so as to generate plasma from the material flowing in the tubular plasma chamber. To cool the tubular plasma chamber, coolant flows through the annular chamber using inlet and outlet ports in the detachable connector units for such flow of coolant.

Modular ICP torch assembly

A host and ancillary tool interface methodology for distributed processing is described. The host tool manages a process, except for the generation of a product used in the process. To generate the product, the host tool provides an indication to an ancillary tool that the product is to be generated, and the ancillary tool generates the product after detection of the indication with no further intervention by the host tool. To provide the indication, the host tool preferably activates a control line whose voltage is monitored by the ancillary tool, or alternatively, sets one or more bits in a memory which is periodically checked by the ancillary tool.
