Grab Sampling · Process Analytical · Field Services
Your one-stop shop for grab sampling systems — and more.
Andon Energy Services specifies, fabricates, installs, and repairs grab sampling and process-analytical systems for refining, petrochemical, oil & gas, semiconductor, and life-science plants across North America.
What We Do
Five service groups, one specialist partner.
01
Process Analytical Integration
We bring grab samplers, online analyzers, and process instrumentation together into one dependable measurement loop — so the sample you pull matches the reading you trust. Integration covers sample conditioning, tie-ins, and commissioning.

Who We Are
A single specialist for the sampling equipment no one else owns.
Grab samplers sit in the gap between a plant’s mechanical, instrument, and analytical teams — which is exactly why they get neglected. Andon Energy Services (AES) exists to close that gap. Since 1991 we have specified, built, installed, and repaired grab sampling systems, and today we integrate them with the analyzers and process instrumentation around them.
From a single sampler repair to a plant-wide reliability program, we bring specialist knowledge, manufacturer-agnostic service, and a safety-first field team to every scope of work.
We exist to close the gap between a plant’s mechanical, instrument, and analytical teams.
About AES →Industries Served
Built for the plants that can’t get sampling wrong.
Petrochemical & Refining
Representative sampling across complex refinery and petrochemical units, where product quality, unit control, and compliance all hinge on getting the sample right.
Oil & Gas
Grab sampling from wellhead to gas processing, upstream to downstream, built for the demanding conditions and remote sites the industry runs on every day.
Semiconductor (High Purity)
Electropolished, ultra-clean sampling for high-purity gas and chemical delivery, where a single point of contamination is enough to scrap an entire wafer lot.
Life Science
Sanitary, validated sampling for pharmaceutical and life-science processes, engineered for contamination-free, repeatable results you can defend in an audit.
Why Andon
More years in grab sampling than anyone in the field.
Starting its involvement in 1991, Andon Specialties has a rich heritage of grab sampling sales, specification, application, manufacturing, construction, and site repair.
Andon Energy Services was created to close a gap: grab samplers don’t fit neatly into any one plant discipline — mechanical, instrument, or analytical — so they need a specialist who lives in all three.
No other company has more years of experience in the sale and field services of grab sampling technologies.
Why choose AES →Safety First
Quality and safety in every project.
We’re a customer-focused team that treats safety as the baseline of every scope, on every site. Our field crews work to plant safety programs and third-party safety-qualification standards, and our safety partnerships hold us to the same requirements our clients live by.
