GREEN alternative to Karl Fischer titration

The Computrac Vapor Pro series of Moisture Analyzers uses a relative humidity sensor-based technology and correlates to the Karl Fischer coulometric titration method (with an oven attachment) in precision and accuracy.  The analyzers do not utilize reagents, minimizing consumables, and is simple to operate.

Computrac Vapor Pro series heats a sample of test material in a septum bottle.  Evolved volatiles are passed to an analysis cell where the moisture content of flowing gas is measured.  A microprocessor integrates the vaying moisture signal and convers the signal to micrograms of water for display.  Results are available in parts per million, percent moisture, or total micrograms of water.

Arizona Instrument's prediction algorithm automatically terminates the test in just minutes when sufficient information is collected to allow accurate determination of the sample's moisture content.  The heating range of the Vapor Pro series is 25°C to 275°C.  Test parameters such as sample size, heater temperature and test ending criteria can be altered to optimize speed and accuracy.

What is Rapid Loss on Drying Technology?

Computrac Moisture Determination provides a method of moisture analysis by utilizing the Loss on Drying (LOD) Method.  Simply press start, and the instrument will tell you what to do!

After taring the pan, a sample is placed on the pan.  The four place analytical balance weighs the initial sample, the ceramic or nickel chromium heating element heats up the sample evenly (no hot or cold spots) to the desired temperature.  Our full service lab develops each customer's parameter set ahead of time (FREE) so the instrument will already know what you want to do - whether that be faster test times or more accurate results, or both.

Loss on Drying is a loss of weight on the sample.  Arizona Instrument is unmatched in terms of accuracy and repeatability, durability and speed.  Our instrumentation is precise enough for a lab environment, with product quality durability.

The heating elements are designed for even heating, to ensure rapid results with high accuracy and repeatability.
