Sample conditioning Systems (SCS)
SCS for analyser system integration
Sample Pre-Conditioning or Conditioning System (SCS) can be necessary to cool the sample, heat up, reduce or boost the pressure or to vaporise from liquid to gas.
Reasons to use a SCS can be:
- Get lowest lag time and best analyser results
- Very high pressure or temperature
- Filtration as soon as possible
- Create fastloop/bypass circulation systems
- Very hazardous sample
- Low pressure or temperature
- Minimising the sample (gas)volume
- Faster response if vaporize liquid sample first to gas.
Mechatest offer a full design and manufacturing capability for the supply of analyser solutions in cabinets and walk-in shelters.
Our solutions are suitable for outdoor use in an industrial environment and ATEX Zone 1 or 2.
After selecting the analysers and designing the sample systems it is very important to choose the environment for the complete system.
The assembly of multiple instruments in a shelter creates several economic advantages:
- Reliable / stable measurement
- A good working environment for monitoring and maintenance
- Lower maintenance costs
- Longer lifespan of the equipment, Etc.
- In a lot of cases a “walk-in” shelter is a very good and durable solution.

Sample Pre-conditioning Systems
The total of the necessary equipment for this is called the Pre-conditioning system.
This system is placed on or near the sample take-off point. The sample pre-conditioning system can typically comprise one of the following components:
- Booster pump
- Pressure regulator
- Vaporising pressure regulator
- Cooling or heating facility
- Pressure or flow indicator
When pressure regulators or vaporising pressure regulators are used, it is very important that the volume between the sample “sample take-off point” and the vaporiser (regulator) is kept to a minimum to avoid long sample time lag.
Sample Conditioning Systems
Sample Conditioning System (SCS) are necessary if some of the functions are not solved in the pre-conditioning;
