Sample probes
Sample probes are designed for extracting a representative portion from the gas sample source in a pipe to the sampling system, and finally the gas analyzers.
Gas probes for sample extraction form a critical point between process and sample conditioning and analysis system. They extract sample gas from the process stream and supply it to the analysis system. They should already remove undesirable particulates at the sampling point and avoid cold spots thus preventing false measurements.

Our comprehensive range of products includes offshore and onshore service, an extensive selection of gas analysis instruments, sample conditioning, and various cabinets and houses for your instruments, tailored to meet the unique requirements of various petrochemical and cryogenic applications. We are dedicated to delivering innovative solutions that ensure accurate and efficient operations in the process industry.

Challenges with gas sampling and sample probes
In the process industry, accurate sample extraction is paramount. However, professionals face three major challenges:
- Undesirable Contaminants: The risk of dust, pipe scale, and entrained liquid drops interfering with the extracted fluid sample.
- Unrepresentative Sampling: Poorly positioned or designed probes might not capture a true representation of the flow.
- Inefficient Sampling: Longer sample times, larger sample volumes, and increased dead volumes.
Our sample probes, tackle these challenges head-on. They ensure the extraction of a true representative portion, filter out contaminants, and optimize sample efficiency. Step into a world of precision with ASaP’s sample probes.

Client quote – after start-up and operation of ASaP FLare Gas Probe
Customer feedback after start-up and operation was:
“Guys, back to office right now from inspection. Filters absolutely clean. Photos will follow in the next days. Seems everything works perfectly.”
The customer response to following question This is really good news! Just a question did you have some upset conditions during the test!
“Good question, I forgot to specify. Obviously, I meant filters clean in presence of several upsets. We had 3 upsets and several small discharges since the installation.”
– a happy customer from the Rotterdam Botlek area.
