Active air sampling vs passive air sampling.

Passive air sampling also referred to as diffusive air sampling passive air sampling basically involves leaving settle plates or contact plates exposed to the air for a certain period of time to collect microbes that may settle onto the surfaces of the plates. Passive sampling however does not require active air. Active sampling involves the use of an air sampling pump to actively pull air through a collection device such as a filter. This article discusses the utility of active air versus passive air settle plate monitoring in a routine environmental monitoring program with an emphasis on the monitoring of the critical grade a environments.

Active sampling unlike passive sampling where a number of agar plates are placed throughout the facility at the same time and then all left to sit for 1 hour active sampling requires an air sampling instrument. Active versus passive air sampling iet september october 2005 author details health safety by eddie salter skc ltd tel. Passive sampling relies on the kinetic energy of gas molecules and diffusion of the gases in an enclosed space onto a sorbent medium.
