The AURA EXV provides steady and reliable heat to vaporize and maintain gas phase of samples for gas chromatography (GC) analysis in applications such as hydrogen sulfide (H2S) measurement in natural gas custody transfer and processing, flare stack emissions monitoring, and carbon dioxide (CO2) beverage analysis. Unlike the standard wire wrapped straight flow path design, AURA’s proprietary labyrinth-style flow path keeps the sample in contact with the heated surface for longer as it traces its way through the large orifice size flow path, minimizing sample condensation through the regulator and across the pressure drop of the seat.  In combination with the large orifice seat, the EXV ensures full sample vaporization and enables the highest flow rate possible, allowing the user to feed multiple analyzers using a single regulator.

The EXV’s exclusive method of heating the sample generates a larger amount of heat using a smaller heater than the standard design, reducing startup times, minimizing the rigors placed on the electronics, and improving analytical reliability by eliminating dual-phase samples. With heater options up to 200 watts, the EXV is effective for use with even heavy hydrocarbon species.

The EXV is available with Dursan® LS inert and anti-corrosive technology that provides superior corrosion resistance versus exotic metals in highly acidic or caustic applications with compounds such as hydrogen sulfide (H2S), hydrogen chloride (HCl), ammonia (NH3), and carbon dioxide (CO2). Each EXV regulator is 100% helium leak checked and undergoes multiple flow and function tests to ensure the highest levels of durability and performance, making it the right choice for vaporizing applications.
