The tedlar gas sampling bags are used in a variety of air sampling applications. These are available in a variety of sizes, ranging from 0.5 to 100 liters.
The stability of 41 selected breath constituents was evaluated in 3 polymer bags (Tedlar, Kynar, and Flexfilm). Species in the C3-C10 chemical class (hydrocarbons, ketones, aldehydes, aromatics, sulfides, and esters) showed excellent recoveries over the investigated storage period.
The gas sampling bags are a simple and cost-effective way to collect part per billion (ppb) to part per million (ppm) levels of inert gases, organic solvent gases, permanent gases, and volatile organic compounds (VOCs) for testing. They are a necessary component of ambient air, indoor air, and stationary source emission testing under EPA rules and guidelines.
Various types of sampling bags are available for different applications and environments. These include sample collection bags, stack sampling bags, vent and flue sampling bags, soil gas sampling bags, TCLP extractions, calibration gas blending and preparation of standards, and air sampling bags.

The Tedlar (Polyvinyl Fluoride) film is a patented product of Du Pont and is the ideal choice for gas sample bags due to its high-temperature resistance, chemical inertness, abrasion resistance, and corrosion resistance. It is also able to maintain the sample's integrity by resisting permeability both inside and outside the bag.
It is a good choice for hot gas and air sampling, particularly in stacks and industrial chimneys where the temperature of the gas is very high. It is a strong, durable, and flexible material that is rated for continuous use from -72 u00b0C to 107 u00b0C when used with appropriately rated fittings.
They are suitable for the collection of mercaptans, hydrogen sulfide, reduced sulfur compounds, and many other atmospheric gases. They have two valve fitting options: push-pull lock (PLV) and screw cap valve (SCV) with Thermogreen LB-2 septa installed inside the valve.
These multi layer foil gas sampling bags can be used to collect a variety of gases, including nitrogen, oxygen, carbon monoxide, methane, and hydrogen sulfide. They are not recommended for collecting volatile organic compounds or low molecular weight compounds that may adhere to the bag's surface or permeate the bag walls and cause degradation of the sample contents.
Sampling bags made from Tedlar (R) or Kynar (R) are extremely chemically inert to a wide range of chemicals. They are a good choice for stack, vent/flue, soil gas, TCLP extractions, and calibration gas blending and preparation of standards.
The Tedlar(r) film is a tough, flexible, and tensile-strength film that is chemically inert to a wide range of chemicals and compounds. It is a preferred choice for VOC and other environmental applications, where it is commonly specified with internal FEP scavenger pipes to ensure complete evacuation of the contents before re-using.
In addition, these bags are suitable for a wide range of temperature conditions. The Tedlar(r) film's maximum operating temperature ranges from 150u00b0C to 170u00b0C, making it an excellent choice for a variety of gas sampling applications.
When using these bags, it is important to store them in a dry area away from sources of light and heat. The carbon black in a Tedlar(r) or Kynar(r) bag may absorb some of the light-sensitive compounds being collected, so use it with caution.
Another type of gas sample collection bags is a whole air grab sample bag that allows users to automatically inflate a sample without the need for an electric pump. These are a popular choice for users who have limited experience using an electrically operated sample bag. They are reusable and can be air shipped for overnight delivery and rush analysis.
