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. Intake filters do not remove these viable particles. Trace Analytics is an A2LA accredited laboratory specializing in compressed air and gas testing for food and beverage manufacturing facilities. Good personal hygiene acts to not only protect the sampling technician from environmental contaminants, but also protects the samples from contamination like shed skin, dirt and dust from street clothes.

The simplest and most economical way to reduce contamination is to work on a cleaned, disinfected work area. Once the flow rate has been established, the air valve to the pressure gauge and flowmeter is closed.

Microbial – Compressed Air Testing – Trace Analytics

ISO designations provide uniform particle concentration values for cleanrooms in multiple industries. The second type of control plate required, is a negative control, or sterility blank.

Slit samplers and sieve samplers are the most prevalent. Maria Sandoval, Microbiologist, Trace Analytics. With new, advanced equipment and a team of microbiologists, our lab is equipped to handle all of your compressed air microbial testing needs. Food facilities must verify and validate the compressed air used ido their facility is appropriate for use and not a source of contamination.


Many accreditation bodies can aid 8573–7 the understanding of microbial limits and specifications, critical to specific industry needs. Some microbial air impact samplers, like the SAS Pinocchio Super II, are designed to diffuse the air flow from a regulated point of use 857-37, and then measure the flow rate to achieve the recommended rate by the OEM.

ISO 8573-7 Micro Testing

Some monitoring plans require that the actual sample number fall within the limitations of the measurement of uncertainty. It is the responsibility of Quality Control Personnel to update and revise this procedure as appropriate.

Maria Sandoval has over 15 years of experience in Microbiology and Molecular Biology.

Always parafilm or tape the plate, this protects the lid from falling off during transit, and keeps moisture in the plate. Microbial contaminants found in the compressor or compressed air lines can be devastating to a final 85773-7 in these industries.

Maintaining control means proper preventative maintenance, microbial monitoring scheduling and risk assessment must be appropriate for the industry being monitored. Microbial Contamination of Compressed Air Compressed air systems can harbor the nutrients required for microbes to grow; namely water, oil, and warm temperatures.

We are happy to discuss your needs and assist you with testing for your operation. Principle of impact using a Microbiological Air Sampler. It should be noted however, that these samples, while informative, are a snap shot of the level of control in the facilities compressed air system. For more information about compressed air quality testing for the manufacturing industry, contact us today. When the iao sample time is completed, the culture plate is removed and incubated for a pre-determined amount of time, and the colony forming units are counted and recorded as CFUs per the volume of measured air.

Trace Analytics, LLC is an Isso Accredited Laboratory specializing in compressed gas analysis for the breathing air, manufacturing, and medical gas industries worldwide. Motion Industries Names New President. These are the only viable microbial specifications and limitations in ISO Afterwards, open the contact plate or petri dish for sampling, the lid should always be placed down, as to not catch any floating microbial vectors like dust inside the lid.


Bacterial spores can be resistant to U. One of a series of standards aimed at harmonizing air contamination measurements, it provides a means of sampling, incubating and determining 8573–7 number of microbiological particles. If you continue to use this site we will assume that you are happy with it. Feel free to place the lid face down inside the sterile bag provided, making sure gloves are clean.

Trace Analytics has a state of the art microbiological testing lab dedicated to compressed air microbial analysis.

Microbial Testing and Compressed Air Standard ISO 8573-7

A regular Micro Testing program can provide insight to a potential problem long before it brings production to a halt. AirCheck Academy Blog Webinars. For instance, if isso 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. If a locking mechanism exists 85573-7 the plate, make certain to lock it once the sample is taken.

The expiration date of the culture plates is over.

Millions of microorganisms enter the air system through the compressor intake. Analyzing micro burden data at point of use outlets throughout compressed air pipeline systems at a given time, acts as a window of observation into the control of the facility.
