RCG Compressed Air & Gas Sampler: Perfect for Compressed Gas Monitoring

It is of critical importance that Pharmaceutical facility process air and gas lines are monitored for microbial contaminants. While air sampling and other quality procedures are obviously required, regulatory standards demand that process air/gas systems used for production activities (e.g., product pushes, overlays, material blow down, etc.) receive routine quality testing, with the same level of quality oversight. The best tool for microbial testing of a compressed air/gas system is a properly designed microbial air sampler.

The RCG Confined Space Sampler

At Emtek, we have a long history of designing easy-to-use, accurate, and reliable air sampling equipment. We know that air monitoring is a key and vital component of your Quality Systems, and that it can impact your production of quality product on a daily basis. Without the right equipment, your tests could be compromised or worse, your product could be at risk of contamination.

That’s why we’ve developed the RCG Compressed Air and Gas sampler. It’s a compressed air/gas monitoring system designed to recover microbial organisms from these critical production systems, and it provides results that you can count on. The RCG is a remote Slit-to-Agar Impaction device that is so compact it can also serve as an ambient air sampler (e.g., as the R2S, or RCG Confined Space Sampler) in areas where most air sampler can’t, or shouldn’t be placed.

A few of the RCG specs include:

• Solid construction: Aluminum/316 stainless steel materials
• Simple cleaning and durability: Clear polycarbonate dome with inlet assembly
• Portable and convenient: 4 lb. weight, 7.5” by 5” diameter
• Flexible sampling: 0-40 minutes of monitoring per cycle
• Quick sampling: Operates at at 50 and 100 LPM for compressed air/gas testing
• Works in conjunction with the EMTEK Microbial High Pressure Diffuser

Compressed Air monitoring is a delicate science that requires only the best equipment. Our air sampling equipment is the best in the industry, and is backed by our incredible support staff and our guarantee that every product we make will exceed your expectations. At EMTEK, we know that manufacturing great equipment is just one small part of keeping clients satisfied. We’re happy to answer any questions you might have to help you find the right microbial air sampler. For more information please visit

Air Monitoring Equipment: Helpful Tips

Air monitoring is a critical component of many Quality Control systems Air monitoring equipment ensures that a work environment is safe for the people working in it, and helps prevent against the spread of contaminates. There are a few different things to consider when implementing an air sampling protocol if you’re looking to guarantee the best possible results.

Understand Environmental Contaminants
Different environments are prone to different types of contaminations, and have different monitoring requirements. In Pharmaceutical, Biotech, and Hospital environments, the air in the clean room environments must be tested for both non-viable particulates (e.g. Dusts, skin flakes, aerosols, , pollen, etc.), as well as viable particulates (e.g., bacteria and mold). Different equipment is required for testing for these two different contaminants, which includes unique sampling equipment for collection and detection. It’s critical that you identify your specific needs before beginning an air sampling plan. Our V100 Controller with our R2S , RAS , or RCG sampling heads , and our P100 air samplers , for example, are designed for the capture of microbial particulates.

Picking a Volume and Rate
Every environment demands its own standard of testing. In some cases, a quick, small sample size is all you need to get an idea of the air quality. In others, you may need a longer sample collection period with a larger total volume, allowing you to gather more particulates and make more inferences about the work environment around the sampler. Different samplers offer different potential total capture volumes (10 cubic feet, cubic meter, etc.) and sample collection rates (e.g., 28.3, 50, or 100 LPM) – -always cross-reference these sampling parameters with your sampling requirements.

The Interface
Much like any other piece of high technology, the data collected from the air sampling equipment is most accurate when the operators using it are appropriately trained.. Spending some extra time or money to purchase a sampler that has an easy-to-use interface often pays big dividends in the end, as it limits the learning curve for new employees and gives you results that you can count on as accurate. User error is a consideration in any field, but user error (e.g., false positives and/or false negatives) with air sampling can have dire consequences (e.g., impact lot release, cause product loses, etc.),.

Overall, choosing air monitoring equipment demands a strong understanding of the fundamentals and a clear vision of your exact needs. Whatever it is that you’re hoping to get out of your equipment will depend on the sampling patterns you wish to follow, and there is sure to be a sampler that falls directly within those parameters.
