Microbial – Compressed Air Testing – Trace Analytics

Paying attention to aseptic technique is imperative to taking a true ido air microbial sample. Slit samplers and sieve samplers are the most prevalent. If you continue to use this site we will assume that you are happy with it. Most pathogenic organisms can begin to be identified from this simple strain. 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.

Breathing Air Distributors Manufacturing Microbial. When using impact samplers, various sampling heads exist to disperse the air onto the recipient agar plate. The simplest and most economical way to reduce contamination is to work on a cleaned, disinfected work area. However, if a facility requires microbial identification, Kso staining is done for bacterial colonies. The blind is taken with the same movements 88573-7 a compressed air sample, but no air is to enter the funnel head or impact the agarose.

You may find it appropriate to establish alternate microbiological action levels due to the nature of the operation or method of analysis. The first action is to always wear the minimum appropriate personal protective equipment, PPE Table 3: Isl from Class ISO 5 environments should normally yield no microbiological contaminants.

ISO 8573-7 Micro Testing

ISO designations provide uniform particle concentration values for cleanrooms in multiple industries. Continual monitoring and quarterly or at minimum biannual testing is recommended.


Many accreditation bodies can aid in the understanding of microbial limits and specifications, critical to ido industry needs. Bacterial spores iao be resistant to U. Microorganisms include bacteria, yeasts, molds and viruses. To learn more about biofilm, read this Microbiology Online article by Fabio Pacheco.

With new, advanced equipment and a team of microbiologists, our lab is equipped to handle all of your compressed air microbial testing needs. For more information please contact Trace Analytics at tel: These are the only viable microbial specifications and limitations in ISO This allows the end user to only monitor the time required to meet the desired total sample air volume; in most cases, 853-7. Specifications do exist for the required blind samples.

Maintaining control means proper preventative maintenance, microbial monitoring scheduling and risk assessment must be appropriate for the industry being monitored.

ISO is an available standard addressing compressed air quality. Values represent recommended levels of environmental quality.

One of a series of standards aimed at harmonizing air contamination measurements, it provides a means of sampling, incubating and determining the number of microbiological particles. The culture sio are contaminated before the use. However, compressed air 8753-7 process air is 873-7 overlooked. Most plates are sent with sterile bags to send back to the testing lab.

This procedure applies for sampling and evaluation of compressed air quality for viable particulates using a Microbiological Air Sampler in Clean Room. The first type of control plates is called blinds, these blinds before and after are to confirm that no outside or unwanted contamination from external variables sampling technicians and the environment have entered the air sampler or agarose surface. When sampling media is placed on the clips for testing, all efforts should be made to avoid secondary contamination.

Biofilm can have negative effects on the compressed air quality as well. The dish shall not subsequently show growth. For simplicity reasons this article will focus on the use of a Pinocchio Super II sampler. These are average values. We are happy to discuss your needs and assist you with testing for your operation. The International Organization for Standardization ISO publishes world-class standards for products, services and systems, to ensure quality, safety and efficiency 1. Taking a small sample of the microbial profile of a point of use environment and growing it up in a laboratory takes skill and awareness.

When in doubt, change your gloves or wipe them down with alcohol. It should be noted that lack of aseptic technique can cause an entire sampling point to fail, resulting in unplanned costs and retesting.

The expiration date of the culture plates is over.

Since no adjustments were made at the inlet valve, the valve to the sampling funnel head can now be completely opened for measurement. Ido level of viable microbiological contaminants in the compressed air shall not be detectable using the method described in clause 7.

Microbial Count Non-sterile applications — Guideline limits to be established based on product bioburden limits. Using ISO isi and analytical methods, their laboratory tests for particles 0. A monitoring program is essential to verify that filtration and routine maintenance is providing the protection required to keep your products safe. 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.

If a locking mechanism exists on the plate, make certain to lock it once the sample is ios. 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.

Further, there is ieo nasty contaminant known as biofilm. Aseptic technique functions to prevent contamination of media and reagents by microorganisms.

Microbial contaminants found in the compressor or compressed air lines can be devastating to a final product in these industries.
