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 air sampling vs passive air sampling.

Active and passive monitoring. 44 0 1258 480188 email. Accurate measurement of air pollutants in outdoor indoor and or personal air is critical for assessing exposure to air pollution and potential health effects. Passive sampler is becoming more and more an effective alternative for conventional active sampler in exposure and health effects studies given its simplicity and low cost.

Airborne gases and vapours are collected by a physical process such as diffusion through a static air layer or permeation through a membrane. Active versus passive air sampling iet september october 2005 author details health safety by eddie salter skc ltd tel. In active monitoring a microbial air sampler is used to force air into or onto its collection medium e g petri dish with nutrient agar based test media over a specified period of time. Active there are two primary methods for microbial 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. Portable samplers such as the sas super 180 allow users to quickly sample at multiple locations within a clean room. Passive sampling relies on the kinetic energy of gas molecules and diffusion of the gases in an enclosed space onto a sorbent medium. 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 involves the use of an air sampling pump to actively pull air through a collection device such as a filter. Passive sampling however does not require active air. 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. Passive sampling however does not require active air movement from a pump.

It is recognized that there has been a long standing historical use of settle plates in the pharmaceutical industry and that european regulatory agencies have supported their use.
