What is Gas and Vapor Exposure Testing?

Gas and vapor exposure testing evaluates the corrosion resistance of materials, coatings, and components when exposed to controlled atmospheres containing corrosive gases.

Laboratory Testing (LTI) performs controlled environmental testing to simulate industrial pollution, chemical vapor exposure, and atmospheric corrosion conditions. Test chambers regulate gas concentration, temperature, and humidity to accelerate degradation and evaluate material performance.

This type of testing is commonly used for electrical connectors, electronic components, coated metals, and assemblies that may be exposed to sulfur compounds, industrial pollutants, or corrosive gases during service.

Capabilities

Laboratory Testing (LTI) performs controlled gas and vapor exposure testing to evaluate corrosion behavior and coating durability in simulated atmospheric environments.

Controlled gas concentration exposure testing
Mixed flowing gas (MFG) corrosion testing
Sulfur dioxide (SO₂) corrosion testing
Controlled temperature and humidity conditions
Exposure of metals, coatings, connectors, and assemblies
Post-exposure corrosion evaluation and analysis

Typical Applications

Gas and vapor exposure testing is used to simulate industrial and environmental corrosion conditions that can degrade materials and protective coatings.

Electrical connectors and electronic components
Industrial equipment exposed to chemical vapors
Automotive and transportation components
Protective coatings and plated metal surfaces
Materials used in chemical processing environments

Test Parameters

Gas exposure testing is conducted under controlled conditions to simulate corrosive atmospheric environments.

Controlled concentrations of corrosive gases
Mixed gas exposure including SO₂, H₂S, NO₂, and chlorine
Controlled chamber temperature and humidity
Exposure durations ranging from hours to extended cycles
Post-exposure corrosion evaluation and performance analysis

I wanted to thank you guys for really coming through for us. You guys were relentless responding to our requests. LTI Rocks!

It was truly a pleasure to work with you and your team at LTI, and I will always cherish the friendship we have developed over the years. I can honestly say there has not been a single incident where LTI disappointed me.

I just wanted to take a moment here to thank you and LTI team for making it a great year for us. I have been recently getting great feedback on the data that I compiled for our project. And needless to say – the only reason I was able to accomplish this was for your timely testing of all the 100s of coupons I had this year. It all so beautifully played out. Really appreciate your on-time turn-around of data, even though I sometimes make it hard for y’all, haha! And also your very prompt responses to my every question. It has been great working with you all this past year and looking forward to the new year. Thank you once again! Heads-up – we have a ton of samples that will be coming your way in the new year!

I cannot thank you and your team enough for giving our needs your top attention. Thanks to the preliminary reports we received from you this morning, we were able to get the approval we needed in time.

Just wanted to recognize you and the lab for getting these plate specimens done on time under short notice. Thanks so much!

I and my entire high-maintenance crew would like to thank you and your whole crew for getting us the results on our last-minute expedite today … each and every one of you is a rock star in our book!
