System Includes:
1x) Moisture Specific Analyzer
1x) Power Cord
1x) Septum Vial (used, this is the one we used once for the video test)
Test seen in video was conducted using corn oil bought from the supermarket. We filled the vial and had it do a ~7 minute run. Results were within expectation.
About this system:
"The Computrac Vapor Pro XL (VPXL) moisture analyzer is a high-sensitivity, moisture-specific laboratory analyzer designed for rapid determination of water content, trace moisture, percent moisture, ppm moisture, and micrograms of water in a wide variety of solid, liquid, powder, polymer, pharmaceutical, chemical, petroleum, lubricant, food, and industrial samples. Unlike conventional loss-on-drying moisture balances, the Vapor Pro XL uses an advanced relative humidity (RH) sensor to specifically measure water released from the sample. During analysis, the sample is placed in a vial and heated under controlled conditions while a user-supplied stream of dry nitrogen or dry air carrier gas transports evolved water vapor to the RH sensor for quantitative measurement. This reagent-free technique provides a convenient alternative to Karl Fischer titration / KF moisture analysis, eliminating Karl Fischer reagents, solvents, electrodes, and titration glassware while allowing detection of moisture concentrations as low as 10 ppm and measurement across a broad 10 ppm to 100% moisture range. The VPXL supports programmable heating from approximately 25°C to 300°C, stepped-temperature methods, customizable test endpoints, stored test programs, moisture curves, and results reported as % moisture, ppm moisture, or µg water. Typical applications include plastics and polymer resin moisture testing, pellets and granules, hygroscopic materials, pharmaceutical raw materials and finished products, chemicals, oils, lubricants, petroleum products, powders, food ingredients, quality control, incoming inspection, process control, product development, R&D, formulation, manufacturing, and laboratory moisture analysis. The Vapor Pro XL technology is also applicable to standardized RH-sensor moisture methods including ASTM D7191 moisture determination in plastics and ASTM D7546 moisture determination in lubricating oils and additives, making it a versatile analytical instrument for laboratories requiring sensitive, selective, and repeatable water-content measurements."
