A plasma torch assembly comprising
- a plurality of tubes;
- a collar integral with at least one tube comprising a first abutment surface;
- a base for holding the tubes during operation of the torch comprising a portion for receiving the collar and a second abutment;
- and
- co-operating interlocking portions for removably urging the first and second abutment surfaces together by relative rotation of the interlocking portions wherein the first and second abutment surfaces comprise a complimentary taper for aligning the collar in concentric formation with at least one other tube on the base by co-operation of the interlocking portions.
A plasma torch assembly comprising:
- a coolant tube comprising a coolant tube body and a collar, an interlocking portion about the coolant tube body;
- a plasma tube for location concentrically within the coolant tube;
- a sample tube comprising a sample tube body and an interlocking portion about the sample tube body for location concentrically within the plasma tube;
- a base comprising
- a passage extending therethrough;
- a cavity on the upper side of the base about the passage;
- at least two interlocking portions including an interlocking portion for coacting with the interlocking portion of the sample tube on the lower side of the base and a interlocking portion for engaging the interlocking portion of the coolant tube on the upper side of the base;
- wherein the plasma tube is immobilised within a cavity in the base;
- the sample tube interlocking portion and interlocking portion on the lower side of the base comprise complementary tapered abutment and complementary threaded portions for interlocking the sample tube and base with the sample tube extending through the passage;
- and the coolant tube interlocking portion and interlocking portion on the upper side of the base comprise complementary tapered portions and threaded portions for locking the coolant tube on the base about the plasma tube.
