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.
How our DRS works:
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:

Instructions for Use of Zefon Respirable Inhalable Sampler (DRS)
Zefon's multi-sampling foam is a specially designed foam insert that can be used with the Zefon® DIS (or traditional reusable inhalable sampler) to enable the collection of both Inhalable and Respirable particles. When inserted into the sampler, inhalable particles are collected on the foam filter while respirable particles are collected on the filter membrane.
Zefon's foam has been evaluated by the Health & Safety Laboratory in the UK to confirm it conforms to the respirable fraction, resulting in the foam removing the inhalable fraction of particles and the respirable portion passing through. Below is a link to a certificate displaying this conformance. Certificate for Batch ZD11-ZD20 (applicable to all lots manufactured to date)
