Undesirable Features
In addition to comparing and contrasting the feature lists of each biogas sampler, you should pay special attention to specific undesirable features that may negatively impact your workspace. For example, unfiltered exhaust air may contaminate the air around the sampler. Some issues to consider include: Particulate emission (material shed from the device), Disruption of laminar airflow (due to the size or shape of the equipment), harborage or release of microbiological contaminants (due to the inability of the equipment to completely sterilize), oversized equipment that is difficult to place, or sample runoff at the test site. Any of these can cause serious problems.
Ideal Features
There are a few ideal features to look for when it comes to air sampling devices. For example, remote operation capabilities allow for greater control over the bacterial air sampler without having to interact directly with it to start, stop, or pause the sampling process. Other notable features include: HEPA-filtered exhaust, simple and easy cleaning and disinfection, compact size and convenient design, no interruption of airflow, discharge of sampled air outside the critical area and little or no particle generation. When comparing these features, you will notice that there are several elements of an air sampler that surpass the sampling rate of the device.
In short, choosing the right air sampler is an important step in maintaining the quality of your working environment. Carefully consider your workflow and needs, and review all the features of a microbiological air sampler to ensure you get a product that meets your needs without compromising the environment.
