  • Patent number: 9649716
    Abstract: Certain embodiments described herein are directed to devices that can be used to sustain a low flow plasma. In certain examples, the low flow plasma can be sustained in a torch comprising an outer tube and an auxiliary tube within the outer tube. In some examples, the auxiliary tube comprises an effective length to match the shape of a low flow plasma sustained in the torch using a flat plate electrode. Methods and systems using the torches are also described.
