The performance of any gas analyzer is only as good as the sampling system supporting it. Proper sample conditioning is essential to ensuring accurate, reliable, and repeatable measurements while protecting sensitive analyzer components from moisture, contaminants, and pressure fluctuations.
Southland Sensing manufactures and supplies a comprehensive range of gas sampling components, including condensers, coalescing filters, pressure regulators, H₂S scrubbers, sample pumps, and flow control accessories. Whether building a new sampling system or upgrading an existing installation, our components help optimize analyzer performance, extend sensor life, and reduce maintenance requirements.
The AMS-100 Series Advanced Membrane Separator provides reliable protection for gas analyzers by utilizing a gas-permeable membrane to prevent liquid carryover and protect sensitive sensor components from liquid slugs. Designed for natural gas sampling applications, the AMS-100 Series can be installed directly on a pipeline or integrated into an existing gas sampling system.
The AMS-100 Series is available in multiple configurations, including the standard AMS-100 separator, AMS-100R with integrated pressure regulator, AMS-100RL with regulator and liquid drain valve, and AMS-100RLBG with regulator, liquid bypass valve, and pressure gauge. Field-serviceable membrane replacement (AMS-PK1) and complete rebuild (AMS-PK2) kits simplify maintenance and help ensure long-term performance.
The CND-225 Stainless Steel Pipeline Condenser provides effective first-stage sample conditioning by cooling the incoming gas stream to promote the condensation and separation of moisture, hydrocarbons, and glycols. Its solid stainless steel construction acts as a passive heat sink, helping remove condensable liquids before they reach sensitive analyzer components.
Engineered for demanding natural gas applications, the CND-225 improves sample quality, reduces maintenance requirements, and helps extend analyzer service life. Designed to operate in conjunction with the AMS-100 Series Membrane Separator, the CND-225 should be installed vertically, upstream of the separator, for effective liquid separation and sample conditioning.
Southland Sensing’s H₂S Scrubber Assembly provides effective sample pre-treatment by selectively removing hydrogen sulfide (H₂S) from gas streams without affecting the oxygen concentration. Ideal for natural gas and other H₂S-containing applications, the scrubber protects sensitive oxygen analyzer components while maintaining measurement accuracy.
The assembly features a transparent polycarbonate body for easy visual inspection of the scrubbing media, which progressively changes color from purple to brown to white as it becomes exhausted. Nickel-plated aluminum end caps provide corrosion resistance, while stainless steel compression fittings allow convenient integration into existing gas sampling systems. The field-replaceable scrubbing media offers a simple, economical maintenance solution, with replacement media available directly from Southland Sensing.
Southland Sensing’s Gas Sample Pressure Regulators provide reliable, single-stage pressure control for demanding industrial gas sampling applications. Featuring a durable piston-operated design, these regulators withstand pressure fluctuations and sudden inlet pressure surges while maintaining consistent downstream pressure. Their adjustable outlet pressure range makes them well suited for high-pressure, low-flow gas sampling systems.
Available with multiple O-ring material options, these regulators accommodate a wide range of process gases, operating temperatures, and application requirements. Their rugged construction and dependable performance help ensure stable sample delivery while protecting sensitive gas analyzers and downstream instrumentation.
Southland Sensing’s Online Gas Sampling Pump provides reliable sample gas delivery for continuous gas monitoring and analytical applications. Featuring a durable single-head diaphragm design and optimized eccentric drive mechanism, the pump delivers consistent vacuum and pressure performance while promoting extended diaphragm and bearing life.
Designed for integration into industrial gas sampling systems, the pump helps maintain consistent sample flow and dependable analyzer operation. For most applications, Southland Sensing recommends installing the pump upstream of the analyzer, where it pushes the sample gas through the measurement system to maintain positive flow, minimize response time, and improve measurement stability.
Southland Sensing’s Gas Sample Coalescing Filters provide high-efficiency removal of condensed moisture, oil, and particulate contaminants from gas sampling systems. Designed for point-of-use installation, these compact filters provide an additional layer of protection for sensitive gas analyzers and downstream instrumentation.
Featuring filtration efficiency of up to 99.99% at 0.01 micron, the filters help deliver clean, conditioned sample gas for accurate and reliable measurements. Their compact design, durable construction, and long service life make them an economical solution for demanding industrial gas sampling applications.
