Searching on the internet today, one can find a plethora of options, ranging from small, sleek portable samplers to robust pieces of equipment like the SAS Pinocchio Super II sampler. Breathing Air Distributors Manufacturing Microbial. Trace Analytics, LLC is an A2LA Accredited Laboratory specializing in compressed gas analysis for the breathing air, manufacturing, and medical gas industries worldwide.

Microbial Testing and Compressed Air Standard ISO | Compressed Air Best Practices

Once the final microbial report has been issued, certain criteria must be met to adhere to ISO Compressed air systems can harbor the nutrients required for microbes to grow; namely water, oil, and warm temperatures. For instance, if the air sample was contaminated with Gram positive cocci bacteria, there is no need to test for Listeria since Listeria is a Gram positive, non-spore forming rod.

Food facilities must verify and validate the compressed air used in their facility is appropriate for use and not a source of contamination.

The dish shall not subsequently show growth. This requires the use of a procedure that accurately measures and samples a specific volume of air for microbial burden analysis inside the tested compressed air system.

Kso is an available standard addressing compressed air quality.

Most pathogenic organisms can begin to be identified from this simple strain. Take your compressed air microbial samples quickly, safely, and in accordance with ISO sampling methods with one of our easy to use, rugged micro samplers.


Always parafilm or tape the plate, this protects the lid from falling off during transit, and keeps moisture in the plate. However, if a facility requires microbial identification, Gram staining is done for bacterial colonies. Air is aspirated at a fixed speed for a variable time through a cover with small holes.

This procedure applies for sampling and evaluation of compressed air quality for viable particulates using a Microbiological Air Sampler in Clean Room.

Microbial – Compressed Air Testing – Trace Analytics

Micro testing is imperative to avoid microbial contaminants inside controlled environments including production areas and clean rooms. The correction adjustment can be utilized on behalf of all perforated sampling heads with hole, hole, or hole impactor for the statistical possibility of multiple particles passing through the same hole on to the agarose surface. Biofilm can have negative effects on the compressed air quality as well. Feel free to place the lid face down inside the sterile 85737- provided, making sure gloves are clean.

Values represent recommended levels of environmental quality. We use cookies to ensure that we give you the best experience on our website. Many accreditation bodies can aid in the understanding of microbial limits and specifications, critical to specific industry needs. When the appropriate time has lapsed to sample liters, the inlet valve is closed, the plate is removed aseptically, labeled, and shipped to the testing lab for analysis. Some microbial air impact samplers, like the SAS Pinocchio Super II, are designed to diffuse the air flow from a regulated point of use outlet, and then measure the flow rate to achieve the recommended rate by the OEM.

The most common 8753-7 about sieve samplers is whether to include the corrections adjustment for the post analysis reporting. Specifications do exist for the required blind samples.

AirCheck Academy Blog Webinars. See Table 2 for calculations of measurement times relative to air flow 857-37. Motion Industries Names New President.


This allows the end user to only monitor the time required to meet the desired total sample air volume; in most cases, liters.

The certificate of the microbial air sampler is expired. Trace Analytics is an A2LA accredited laboratory specializing in compressed air and gas testing for food and beverage manufacturing facilities. The simplest and most economical way to reduce contamination is to work on a cleaned, disinfected work area. Bacterial spores can be resistant to U. Remember to always 85573-7 in mind of the measurement of uncertainty that ISO labs report. When in doubt, change your gloves or wipe them down with alcohol.

A monitoring program is essential to verify that filtration and routine maintenance is providing the protection required to keep your products safe.

The additional use of settling plates is optional. Testing compressed air may not seem like the proverbial environmental sample, but it is. When sampling media is placed on the clips for testing, all efforts should be made to avoid secondary oso. This article will focus on ISO normative test methods and analysis for viable microbiological contaminants and how it can be fundamentally utilized in compressed air microbial monitoring plans. Microbial Contamination of Compressed Air Compressed air systems can harbor the nutrients required for microbes to grow; namely water, oil, and warm temperatures.

ISO 8573-7 Micro Testing

Modern compressor systems, which are properly maintained, should have properly sized filtration and point-of-use filters to remove these contaminants. Further, there is another nasty contaminant known as biofilm. The level of viable microbiological contaminants in the compressed air shall not be detectable using the method described in clause 7.
