The Gilian® brand name is known for personal and area air sampling pumps, air flow calibrators, and equipment that are tough, dependable, and perform to the highest standards required by industry professionals. Today’s Gilian pumps retain the same quality that industrial hygienists and occupational health & safety professionals have trusted for decades, however the added features and user-friendly interfaces make the pumps easier to use and more productive. The Gilian Air Sampling Pump line includes personal and area pumps for the evaluation of worker exposure to airborne hazards.
Air sampling pumps are essential for drawing a known volume of air through a collection device (e.g., filter cassette, sorbent tube) to capture airborne contaminants. This allows for subsequent analysis by a qualified lab to determine the concentration of these contaminants. Pumps are available in various flow ranges, and choosing the right pump is crucial for accurate measurements.
There are both personal and area air sampling pumps available. Personal pumps are typically small, portable, and designed to be worn by workers to monitor their individual exposure. Personal pumps can also vary by flow range and back pressure capabilities. Area air sampling pumps, are generally larger in size, not meant to be worn and can draw higher flow rates (30 LPM).
Calibration of air sampling equipment is critical to ensure the accuracy and reliability of air sampling data. Calibration equipment such as the Go-Cal Pro (portable) Gilibrator 3 (dry cell) and Gilibrator-2 (wet cell) are used to adjust the flow rate of air sampling pumps and validate drift in flow rates between starting and ending values. These devices measure air volume accurately and therefore provide a reference point. Proper calibration ensures that the volume of air sampled is known, leading to accurate reporting of contaminant concentrations.
Air sampling uses various collection media, including filter cassettes, sorbent tubes, impingers, and gas bags.
The selection of the appropriate collection media depends on the nature of the contaminant being sampled, including its physical state (gas, vapor, particulate), concentration, and the analytical method to be used. The Sensidyne Catalog (p. 39) offers a contaminant reference guide to aid in the selection of the appropriate method and corresponding media.
A complete air sampling system typically consists of
The selection of the proper components begins with the contaminant you are looking to measure. Other considerations include the environment where the sampling will take place, how much material will need to be collected and the analysis you are going to perform. The Sensidyne Catalog (p. 4) offers guidance on specifying your air sampling train.
