The Zefon Disposable Respirable Inhalable Sampler (DRS) is a modified variation of the Zefon Disposable Inhalable Sampler (DIS). The DRS adds a certified foam insert that has a collection efficiency that closely matches the ISO 7708/CEN convention for respirable dust. This eliminates the need for the use of a cyclone to collect the respirable dust. The DRS meets the criteria of a sampler for the OSHA permissible exposure limit (PEL) of Respirable Crystalline Silica.
Using our disposable respirable inhalable sampler first requires calibration to ensure sampling accuracy. The steps in the calibration process include:
After calibration, you're ready to start sampling. The process entails:
The Disposable Respirable Inhalable Sampler from Zefon International includes a host of features and benefits that simplify the sampling process, increase accuracy and reduce costs:
Two types of inhalable samplers are available: disposable and reusable models. A reusable version features a lower unit cost, and the fact that you can wash it and use it repeatedly translates to lower long-term ownership costs. On the downside, reusable samplers require frequent care to ensure they remain free of contaminants.
It's also possible that workers can make a mistake when pre-assembling the cassettes, as well as when matching the cassette with the correct filter or back. Another potential risk is that users could attach the wrong clip when shipping the cassettes to the testing lab, which could produce inaccurate sampling results.
Perhaps the most important advantage of choosing a disposable sampler is that the cassettes come already loaded, which eliminates the hassle of assembling them and prevents errors. You also won't have to worry about cleaning or caring for the cassettes, which saves time and substantially reduces the risk of contamination. What's more, disposable samplers weigh less than their reusable counterparts, which can enhance testing results and improve sampling accuracy.
The only significant disadvantage of using disposable samplers is that they might not provide the most cost-effective solution for sampling operations that have the resources and equipment to manage the handling and control process with efficiency.
