As technology evolves to produce smaller, more capable and cost-effective analyzers, it gives industry the ability to measure trace components at extremely low levels. Reducing the trace levels of moisture, oxygen, or contaminants can improve device quality and yields.

Moisture content can have disastrous effects, even in the single-digit ppm range of moisture concentration. When liquid hydrocarbons and excess water vapour combine to form a hydrate and are present in the sample stream; they can reduce flow, damage equipment such as valves and compressors and obstruct areas of the piping. The lifespan of process piping is determined by the effects of corrosion present once it has been oxidized with the presence of moisture. The measurement of moisture in gas is an important parameter for processing, storage, transportation, and global conformance specifications.

Increased global competition and the need to improve production efficiency while providing consistency in quality controls are driving our industry partners to enhance measurements. Requirements for results in the single-digit ppm range or even the ppb measurement range and the high sensitivity dew point accuracy of +/- 0.5°C are becoming more common. Results in a matter of seconds rather than hours are in demand. The sampling experts at A+ Corporation worked with industry partners to develop the latest in our Analytically Correct™ Engineered Sample Systems line, Trace Moisture System for Trace Measurement Sampling. This trace measurement system is designed to produce an Analytically Correct™ sample for analysis in association with a trace moisture analyzer for fast, reliable results.



Known to be the safest, most versatile probes on the market, they are adjustable in length, low volume and can be easily inserted into pressurized sources. Available with or without a membrane tip, these sample probes can be used for sampling from a gas or liquid source.


Genie pressure regulators are designed specifically for gas sample handling. The self-limiting heater block on either the single-stage GHR or the four-stage JTR-H compensates for the JT cooling effect during the pressure reduction process of high dew point gases or due to low operating temperatures.


The smooth machined surfaces of the entire sample path are coated to help minimize sample delay associated with adsorption. Treated surfaces are more inert and durable, thus preventing corrosion and fouling.


This insulated sample system case allows the sample pressure and enclosure temperature to be monitored at a quick glance, without having to remove the enclosure. For complete access to system components, one or both sides can be completely removed. Additionally, the entire system is mounted to the enclosure coupling, NOT the probe like other systems on the market. Insert and retract your sample probe freely by completely removing the enclosure while keeping all other components, such as filters, external regulators, gauges, and tubing, undisturbed. This patented technology is the first of its kind saving maintenance time and eliminating field frustrations.
