The method determines oxygen transmission by measuring the oxygen that permeates through a specimen into an oxygen-free carrier stream. The test specimen separates the diffusion cell into upstream and downstream sides maintained at the same total pressure. High-purity oxygen flows across the upstream surface, while dry, oxygen-free nitrogen sweeps the downstream surface. With equal total pressure on both sides, oxygen permeation is driven by the difference in oxygen partial pressure across the specimen.\u003c\/p\u003e\n\u003cp\u003eDuring testing, oxygen first dissolves into the material surface, diffuses through the polymer structure, and then desorbs into the nitrogen carrier stream. The carrier gas transports the permeated oxygen to the coulometric sensor, which operates as an electrochemical cell. Oxygen molecules reaching the sensor undergo reduction at the cathode and generate a predictable electrical charge. The resulting electrical current is proportional to the oxygen flux passing through the specimen. This provides an absolute measurement based on Faraday's law, rather than a relative measurement that depends on gas-specific calibration.\u003c\/p\u003e\n\u003cp\u003eThe instrument calculates the oxygen transmission rate (OTR) using the stabilized sensor current, carrier-gas flow rate, and exposed test area for film specimens. For finished-package testing, the calculation can be based on the complete package under the applicable test configuration. Controlled relative humidity is important for materials such as EVOH and nylon, where oxygen barrier performance can change significantly with moisture content. The ToronOTR™ 1 conditions the gas streams to the specified relative humidity to support controlled and repeatable testing conditions.\u003c\/p\u003e\n\u003cp\u003eThe single-cell configuration measures one specimen at a time, providing a focused testing setup for laboratory OTR measurements. An optional temperature controller maintains the measurement cell at a defined temperature, supporting isothermal testing when controlled temperature conditions are required.\u003c\/p\u003e\n\u003ch2\u003eOxygen Transmission Rate Tester (Single-Cell) - ToronOTR™ 1 Technical Specifications\u003c\/h2\u003e\n\u003ctable class=\"table\" border=\"1\" cellspacing=\"0\" cellpadding=\"0\" width=\"850\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eFilm Test Range (Standard)\u003c\/td\u003e\n\u003ctd\u003e0.01 to 6,300 cm³\/m²·d\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFilm Test Range (Optional)\u003c\/td\u003e\n\u003ctd\u003e0.07 to 63,000 cm³\/m²·d\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFilm Resolution\u003c\/td\u003e\n\u003ctd\u003e0.001 cm³\/m²·d\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage Test Range\u003c\/td\u003e\n\u003ctd\u003e0.0001 to 62 cm³\/pkg·d\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage Resolution\u003c\/td\u003e\n\u003ctd\u003e0.00001 cm³\/pkg·d\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpecimen Amount\u003c\/td\u003e\n\u003ctd\u003e1 (single specimen)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperature Range\u003c\/td\u003e\n\u003ctd\u003e5°C to 95°C (with temperature controller)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperature Accuracy\u003c\/td\u003e\n\u003ctd\u003e±0.1°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHumidity Range\u003c\/td\u003e\n\u003ctd\u003e0% RH;

Method\u003c\/h2\u003e\n\u003cp\u003eThe coulometric sensor method used by the ToronOTR™ 3 is an equal-pressure (isostatic) technique for measuring oxygen transmission rate (OTR) by monitoring oxygen that permeates through a specimen into an oxygen-free carrier stream. In each test cell, the specimen separates the chamber into upstream and downstream sides maintained at the same total pressure. High-purity oxygen flows across the upstream surface, while dry nitrogen sweeps the downstream surface. With equal total pressure on both sides, the oxygen partial-pressure difference provides the driving force for permeation.\u003c\/p\u003e\n\u003cp\u003eOxygen first dissolves into the film, then diffuses through the polymer structure before desorbing into the nitrogen carrier stream. The carrier gas transports the permeated oxygen to the coulometric sensor, an electrochemical detection cell in which oxygen undergoes a reduction reaction that generates a measurable electrical current. Because the generated charge has a defined relationship with the amount of oxygen reaching the sensor, the measurement is based on Faraday's law and provides a direct determination of oxygen flux rather than a relative measurement requiring gas-specific calibration.\u003c\/p\u003e\n\u003cp\u003eThe system determines the OTR for each specimen using the steady-state sensor current, carrier-gas flow rate, and exposed test area. For finished-package testing, the measurement can instead be based on the complete package being evaluated. Water-bath temperature control maintains all three test chambers at a consistent temperature, while controlled relative humidity conditions the gas streams to reproduce specified moisture conditions. This is particularly relevant for polymers such as EVOH and nylon, whose oxygen barrier performance can vary with humidity.\u003c\/p\u003e\n\u003cp\u003eThe three test cells operate in parallel and provide independent measurements for each specimen. This configuration allows three OTR values to be generated from a single test setup, supporting higher sample throughput for packaging development, quality control, and materials research.\u003c\/p\u003e\n\u003ch2\u003eOxygen Transmission Rate Tester (3-Cell) - ToronOTR™ 3 Technical Specifications\u003c\/h2\u003e\n\u003ctable class=\"table\" border=\"1\" cellspacing=\"0\" cellpadding=\"0\" width=\"859\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eFilm Test Range (Standard)\u003c\/td\u003e\n\u003ctd\u003e0.01 to 6,500 cm³\/m²·d\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFilm Test Range (Optional)\u003c\/td\u003e\n\u003ctd\u003e0.07 to 65,000 cm³\/m²·d\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFilm Resolution\u003c\/td\u003e\n\u003ctd\u003e0.001 cm³\/m²·d\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage Test Range\u003c\/td\u003e\n\u003ctd\u003e0.0001 to 62 cm³\/pkg·d\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage Resolution\u003c\/td\u003e\n\u003ctd\u003e0.00001 cm³\/pkg·d\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpecimen Amount\u003c\/td\u003e\n\u003ctd\u003e3, independent\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperature Range\u003c\/td\u003e\n\u003ctd\u003e5°C to 95°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperature Accuracy\u003c\/td\u003e\n\u003ctd\u003e±0.1°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHumidity Range\u003c\/td\u003e\n\u003ctd\u003e0% RH;
