The OxyTraQ® system is a fast, easy to use multi-station oxygen permeation testing instrument. The OxyTraQ® oxygen permeation system delivers fast, reproducible results. Samples can range from: small bottles implementing the latest in oxygen scavenger technology, half gallon polyolefin bottles, and film samples. The OxyTraQ® system eliminates the deficiencies associated with current test systems.

The user-friendly software (included) allows the operator to easily track multiple samples, or multiple tests of the same sample. The device contains individual sensors for each of the six stations, so the software continuously tracks and displays real-time permeation data for each station. An overview screen in the software displays all of the stations' real-time graphs at once. With a simple click the user can analyze individual stations. The software's searchable database makes sure your data is instantly retrievable, and also allows the user to export data in many formats!

Product Features

• Reliable and repeatable test platform.
• High throughput
• Universal PTI CTU system eliminates the need to use single sample fixtures for each test. No copper piping or ferrules. No conversion needed between bottle and film testing.
• Intuitive setup and operation with the included sophisticated software
• Detailed charting allows results to be interpreted more quickly than systems on the market today.
• Samples can be removed from the test station, placed on a purge rack and then returned for test at a later time with no degradation of the test. Perfect for testing oxygen scavengers.
• User-friendly software tracks real-time data from every station, and stores completed tests in a searchable database.
• Measurement data software providing data plotting and data output capability for statistical data recording.
• System designed for both bottles and films samples.
• System protected by the SmartPurge™ cycle. (see explanation below)

Container Transfer Unit

A critical component of the OxyTraQ® system is the exclusive Purge Rack System equipped with the OxyTraQ® Container Transfer Units (CTU - patent pending). CTUs eliminate the need for bottles to sit on the testing device for weeks at a time while the bottles reach equilibrium. After a bottle is mounted on the CTU, the CTU is placed on the Purge Rack where it is flushed with the same gas mixture used in the OxyTraQ® system. Once the bottle reaches equilibrium, it can then be quickly and easily transferred to the OxyTraQ® system (in just seconds!) where final permeation values can be generated in less than one day. Increase your throughput and increase valuable test station efficiency!

SmartPurge™ Cycle Feature

The SmartPurge™ cycle was established to protect oxygen sensors. The life of an oxygen sensor is directly proportional to the amount of oxygen to which it is exposed to. Thus one would want to expose such sensors to oxygen only when interested in knowing oxygen content of the sample gas.

The SmartPurge™ cycle is part of an entire system consisting of a microcontroller, valves, and sensors. In addition to the oxygen sensor, there is a sample sensor which detects the presence of a properly positioned CTU and a pressure sensor which monitors the carrier gas. The SmartPurge cycle uses feedback from these components to control automatic valves used to direct gas flow. A microcontroller running continual algorithms monitors and controls the entire system.

In essence, the SmartPurge cycle is a bodyguard that continually monitors the status of multiple test stations. It purges each sample individually and only for the amount of time required. The system will allow the samples to begin continual testing once oxygen levels are within range and the sample is nearing equilibrium. If the system detects a problem at any given time, on any station, it will protect the sensor at that station. In addition to everything mentioned, if the carrier gas pressure drops below a set threshold at any given time, all sensors will be protected and testing will be put on pause until the pressure is recovered. Once pressure is recovered (generally when the Nitrogen tank is replaced) the SmartPurge™ cycle will resume.
