Things to Know About Air Sampling Procedures


Air sampling is the monitoring of quality of air by measuring and analysing pollutants found in a sample taken from a specific area. It is an effective protection method, since it can detect the presence of potentially harmful pollutants in the environment, particularly man-made contaminants, before the harmful effects of these pollutants occur on the residents.

Therefore, it is of the highest significance that air sampling is carried out efficiently and reliably in order to better protect the health of staff and all persons exposed to potentially harmful situations. Mentioned below are a few tips on how to conduct a safe air sampling procedure.

Direct Reading Instruments

Direct reading Instruments are intended to quantify the presence in the air of a specific pollutant, such as a gas, vapor, or a particle, and to calculate how often the particular substance’s presence may be harmful to a person.

These instruments support the process by showing air quality measurements in real-time or near real-time, facilitating continuous air monitoring if appropriate. They are the key instruments for the initial characterization of the site. The information provided by direct-reading instruments can be used to institute adequate safety measures, define the most suitable equipment for further monitoring, and establish effective sampling and analytical protocols.

Spectroscopic Analysis

To obtain information on its materials, spectroscopic analysis requires transmitting light through a sample. This is achieved in the form of air sampling, in the filter of a sampling system. As air moves through the filter, the amount in which the contaminant is present in the sample can be measured using spectroscopy.

There are many methods for conducting a spectroscopic analysis. While visible light is part of its spectrum, by using invisible light instead, it aims to provide more helpful information. The electric radiation in the electromagnetic spectrum outside the spectral area is referred to as invisible light.

Personal Devices

Personal sampling instruments are meant to sample and calculate the air that surrounds the person wearing them directly. This is a substitute for a physical air monitor, except for the fact that it is portable device. They are made to put on the head unobtrusively, like a regular lamp with the hat. These devices are particularly ideal for coal miners, who may be exposed to high amounts of silica dust, and people employed in chemical laboratories who may be exposed to several dangerous gases.

Regular Sampling

To accurately measure an environment’s air quality, it must be routinely performed. When a workplace is overly crowded, and when toxins are most likely to be found in the air, attention needs to be given. In addition, it is important to know the appropriate levels for each potentially dangerous contaminant to make sure that the environment can be cleared or that ventilation can be improved if important. An air sampling procedure without information of sufficient air quality is pointless.

A proper technique for the air sampling is an essential protection technique in every industrial setting. You can quickly detect air quality inside the office premises and workstations with the aid of air sampling instruments.
