1. A probe assembly for processing an outlet gas from a gas analyzer, wherein the outlet gas contains a volatile carrier gas, and wherein the probe assembly comprises:
a. a thermowell with a thermowell bore; b. a heating element adapted to mount in the thermowell bore, the heating element connecting to a power connection and when energized, the heating element heats the thermowell; c. a one piece non-sintered metal probe comprising:
(i) a mounting nut with an inner threaded bore, outer threads and an outer thread outer diameter; and(ii) a tubular body with a tubular body outer diameter integral with the mounting nut, wherein the tubular body outer diameter is smaller than the mounting nut and outer thread outer diameter, the tubular body further comprising:
1. an outer surface;2. a tubular body inner bore;3. an end cap with an end cap inner bore, wherein the end cap inner bore fluidly connects to the tubular body inner bore, and the end cap has an end cap inner bore diameter that is smaller than a tubular body inner diameter;4. a plurality of upper longitudinal outer grooves formed around the end cap with each upper longitudinal outer groove penetrating to the tubular body inner bore without penetrating to the end cap inner bore; and5. a plurality of longitudinal slots, each of the plurality of longitudinal slot extending from the outer surface to the tubular body inner bore; d. a catalyst cartridge with a central cavity, wherein the tubular body has an interference fit within the central cavity and rests on the mounting nut; e. a street tee with a first tee end, a second tee end, and an inlet port, wherein the first tee end threadably engages the thermowell, the second tee end threadably engages the inner threaded bore of the mounting nut, and the inlet port is adapted to receive the outlet gas from the gas analyzer; f. a sintered metal outer housing threadably engaging the outer threads of the mounting nut while simultaneously enclosing the catalyst cartridge, wherein the outlet gas containing the volatile carrier gas is received from the gas analyzer and continuously flows between the thermowell and the tubular body into the catalyst cartridge for reaction, the catalyst cartridge producing water vapor and carbon dioxide while the sintered metal outer housing simultaneously allows two-way gas flow of an ambient air to the catalyst cartridge while exhausting the water vapor and carbon dioxide; and g. a junction box threaded to the thermowell for supplying power to the heating element; and
wherein the probe assembly produces (i) zero backpressure of outlet gas to the gas analyzer or (ii) outlet gas at a constant value while (iii) continuously flowing outlet gas into the probe assembly for continuous conversion of the outlet gas to water vapor and carbon dioxide at a rate up to 1 liter per minute. |
