The OTR Advantage: Reliable Oxygen Transmission Testing for Rubber and Barrier Materials

In rubber compounds, elastomers, barrier films, and multilayer structures, oxygen transmission data does more than fill a test report. It supports formulation decisions, quality release, and long-term performance confidence. The Systech Illinois OxySense 8101e is built for labs that need dependable OTR results across a wide range of material behaviors.

Why OTR testing matters

Reliable oxygen transmission data supports better product decisions

Rubber and elastomers: Air retention and barrier performance directly influence consistency, service life, and product reliability.
Barrier films and laminates: OTR values help teams verify whether a structure will protect the product as designed.
QA and R&D: A result only becomes useful when it is repeatable, fast enough for workflow demands, and defensible during audits or customer reviews.
Lab efficiency: The challenge is not only measuring oxygen transmission accurately, but doing so across multiple materials and test conditions without unnecessary downtime.

When oxygen transmission data is unreliable, downstream decisions become unreliable too. That is why broad range, repeatability, and independently verifiable performance matter just as much as sensitivity.

What engineers and QA teams need from OTR data

For rubber, elastomer, barrier film, and multilayer structures, the key question is rarely whether oxygen transmission can be measured. The real question is whether the measurement stays accurate, repeatable, and practical across very different permeability behaviors.

01

Coverage across diverse materials

Labs often need one platform that can handle both high-barrier samples and highly permeable materials without switching systems.

02

Multiple condition profiles

Temperature and humidity can change the behavior of rubber and barrier structures significantly, so a single-condition result is not always enough.

03

Protection against abnormal samples

Pinholes and unexpected high-transmission specimens can disrupt a testing schedule and create avoidable maintenance cost if the sensor is not protected.

04

Repeatable test end points

Operator guesswork around equilibrium increases variability and can waste gas, time, and sensor life.

05

Defensible validation

Labs increasingly need not just repeatable numbers, but results that can be independently verified when customers or audits demand proof.

Method and validation context

ASTM D3985 context The platform is engineered for performance comparable to ASTM D3985 requirements for oxygen transmission testing.
Open-loop validation 3rd-party certified gas standards support independent verification instead of closed internal-only checks.
Audit-ready confidence NIST-traceable validation strengthens data credibility for regulated and quality-sensitive environments.
Higher productivity Condition automation and faster wet-to-dry transitions reduce idle time between studies.

The OxySense 8101e advantage

Reliable OTR testing without narrowing your material range

The OxySense 8101e combines wide-range sensing, automated condition control, and practical protection against abnormal samples. The result is a testing workflow that stays useful across rubber, elastomers, barrier films, and related materials.

1. Wide measurement range for diverse materials

Its eMetric sensor technology covers 0.05 to 432,000 cc/(m2.day), allowing one instrument to span high-barrier structures and high-transmission samples.

  • Supports variable permeability behavior on one platform
  • Reduces dependence on multiple dedicated systems
  • Improves continuity between R&D and QA work

2. Faster material profiling with TCM

The Test Condition Matrix feature enables testing at up to ten temperature and humidity conditions with a single setup.

  • Build broader performance profiles with less operator intervention
  • Reduce repeated setup time between condition changes
  • See how materials behave across real operating environments

3. Better protection from sample surprises

Oxygen surge protection detects excessive oxygen levels and helps protect the sensor when pinholes or very high-transmission samples appear.

  • Helps reduce unplanned downtime
  • Protects against avoidable sensor damage
  • Improves resilience in routine production testing

Additional workflow advantages

4. Auto-Stop at true equilibrium

Auto-Stop determines when the sample has truly reached equilibrium and ends the test automatically, improving repeatability while reducing operator guesswork.

5. Rapid wet-to-dry conversion

Moving from saturated wet testing to dry testing in minutes rather than hours increases daily throughput in busy QA and R&D labs.

6. Confidence through independent verification

Open-loop validation with 3rd-party certified gas standards provides independently verifiable, NIST-traceable confirmation of instrument performance.

Where this matters most

The strongest fit is in labs that need dependable oxygen transmission data across a mix of materials, structures, and condition profiles without sacrificing throughput.

A

Rubber air-retention applications

Useful where permeability affects retention performance, service life, and consistency from batch to batch.

B

Barrier films and multilayer laminates

Supports evaluation of structures where oxygen ingress directly affects product protection and shelf life expectations.

C

Coated and specialty materials

Helps teams understand how coatings, formulations, or process changes alter oxygen barrier behavior.

D

QA release and troubleshooting

Useful for release confidence, comparative screening, and investigation when abnormal samples or leaks appear.

What the data supports

Material screening Compare grades, structures, and compounding changes without moving to a second platform.
Condition sensitivity analysis Understand how temperature and humidity influence barrier performance, not just one static outcome.
Faster QA decisions Reduce manual interpretation at equilibrium and move wet-to-dry studies through the lab faster.
Defensible reporting Support customer, internal, or audit conversations with independently verifiable instrument checks.
