Introduction to the RCG Comp Gas Sampler
The Remote Compressed Gas/Confined Space Sampler (RCG) is a specialized monitoring device designed for professionals who need accurate air quality assessment in difficult or hard-to-reach locations. This advanced sampling equipment is important in various industries where air quality monitoring is essential for safety, compliance, and quality control.
What is the RCG Comp Gas Sampler?
The RCG Comp Gas Sampler is a remote Slit-to-Agar Impaction sampling device that allows for sampling of compressed air and gas systems and critical areas where a sampling device cannot be directly placed.
This specialized equipment enables testing in environments that would otherwise be difficult or impossible to monitor, making it an invaluable tool for:
- Pharmaceutical manufacturing
- Food and beverage production
- Healthcare facilities
- Industrial environments

- Any setting requiring compressed air quality verification.
How the RCG Comp Gas Sampler Works
The RCG Comp Gas Sampler uses the Slit-to-Agar Impaction method to collect samples, which is a proven technique for microbial monitoring. This process includes the following steps:
- Air is drawn into the sampler at a controlled rate
- Microorganisms and particles directly impact the agar surface
- The collected sample is then incubated for analysis
- Results are evaluated against established standards
This methodology ensures accurate and consistent results in various monitoring scenarios.
