Applications

AerospaceProduction of extremely high-specification aeronautical parts can require vacuum furnace heat treatment using very dry argon. NADCAP standards also specify testing welding shield gas at the torch head to ensure dryness. Continuous measurement of trace moisture ensures that the feed gas used for shielding remains within the specified moisture content range, allowing operators to maintain ideal conditions.

Food and BeverageIncorrect levels of moisture in foodstuffs can lead to loss of food quality. The shelf life of foods packaged in plastic can be extended by replacing ambient air with very dry gases such as Nitrogen and carbon dioxide between the foil layer and the food. The continuous measurement of trace moisture can significantly reduce waste and carbon footprint.

HDPE ProductionEthylene and propylene are perhaps the two most important compounds used in industry today, acting as building blocks for manufacturing a wide range of chemicals and plastics. Accurate and consistent measurement of trace moisture will help with process optimisation, prove gas product quality and polymerisation yield, and reduce corrosion in pipelines and maintenance costs.

Injection MouldingMoisture adsorbed on the surface of plastic pellets that feed injection moulders can cause extrusion failures, decreasing the strength of the product and affecting its surface finish, colour and opacity. Dry air circulates through the pellets, removing moisture, and ensuring they are dry. Increase process efficiency and decrease costs by measuring trace moisture to detect any failure of the dryer.

PharmaceuticalsExcessive or deficient moisture content can impact the physical properties of a pharmaceutical product, affecting the product’s chemical reactivity, binding properties and shelf life. Moisture content fluctuates from batch to batch, so a reliable method is required to determine accurate moisture content and achieve consistency. The trace moisture measurement instrument must be fast, repeatable and accurate for continuous online dewpoint control of blanketing gases.

Welding GasesWelding takes place in an atmosphere shielded by inert gases and different welding jobs require various inert gases. Monitoring oxygen levels is key to producing high output and superior weld seams. By continuously measuring moisture, the feed gas used for shielding remains within the specified moisture content range, allowing operators to maintain ideal conditions for welding.
