In order to collect air and gas samples for assessing stationary source emissions, industrial air, and ambient air, gas sampling bags are utilized. These sampling bags are reusable, mechanically robust, leak-tested, and chemically inert.
Cali-5-Bond(tm) multi-layer foil sample bags are an easy and dependable way to gather and deliver air, gas, or liquid samples to a central testing device or distant lab for examination.
The Cali-5-Bond(tm) gas sampling bag is made of a very flexible sheet that is resistant to air, gas, or liquid permeability by fusing together several layers of polymer material. It is perfect for gathering air samples in difficult-to-reach places where using typical gas sampling bottles is unsafe.
The Cali-5-Bond(tm) air/gas sampling bag is made using a unique manufacturing method that bonds several layers of plastic together to form an exceptionally impermeable barrier that prevents sample loss due to intrusion of air, gas, or liquid. It is advised to use this type of air/gas sample bag between 40u00b0 and 45u00b0 C. (110deg-115degF).
The Cali-5-Bond(tm) bag may be inflated to a maximum of 7.0" WG (17.4 mbar, 0.25 psi) when utilized for stack sampling applications before a leak can happen. This is crucial to take into account for stack sampling since a sample may leak out of a sample bag at higher flying altitudes due to increased pressure.

Fluoropolymer (FEP) gas sample bags are flexible, sturdy and heat sealed on all four sides. They are chemically inert to most chemicals and have low permeability, which limits sample loss.
These 5 mil thick, heat sealed FEP fluoropolymer film bags come in a variety of sizes with optional metal eyelets for easy holding and storage. They are a great choice for the plethora of chemically demanding airborne hazards such as odors, volatile organic compounds, H2S and light gases.
These bags are the most inert of the lot and offer a unique feature, namely a thermometer incorporated into the patented valve. The aforementioned feature allows for continuous use temperatures of -98 deg to 400 deg (temperature limit depends on fittings used). In addition, the bag is also leakproof and has an impressive number of other functionalities such as a self-sealing PTFE valve that eliminates O-rings from being used. This is a truly innovative, yet simple to operate, high performance sampling bag that will save your company money in the long run.

PVC is a versatile material that offers an economical gas sampling solution. However, PVC contains plasticizers that could leach and contaminate gas sample collection bags.
The patented Cali-5-Bond(tm) production process bonds multiple layers of polymer together to create an air, gas and liquid barrier. A layer of aluminum foil and a proprietary formulation of HDPE form the totally inert inner-liner.
A molded, sanitary stopcock valve is also available. This optional self-sealing stopcock is directly connected with a clockwise twisting motion to either the stopcock base alone or to the top of the stopcock-valve assembly, and permits direct syringe injection/withdrawal of sample gas or liquid without any dead space effect.
A standard with all Luer-Fit Valve(tm) is a Quik-Mate(tm) Connector, which is a flow-through adapter for instant (push-pull) connection of tubing to the valve. As pressure is applied, the Quik-Mate(tm) becomes tighter, and a gas-tight seal is assured between the sample line tubing and the Luer-Fit Valve(tm).

The Tedlar(r) sampling bag is a flexible enclosed gas sampling container designed to collect samples of gaseous species. It is suitable for industrial and environmental gas sampling procedures. It can be used to sample a variety of gases, including inert gasses, organic solvent gases, permanent gasses and volatile organic compounds (VOCs).
A typical use is to collect ambient air or indoor air samples, or stationary source emission testing. These bags are able to collect samples at part-per-billion (ppb) to part-per-million (ppm) levels of inert and organic gasses, as well as permanent and volatile compounds.
In addition to the physical integrity of the sample, a good quality sampling bag should also allow for long term storage without significant change in the sample, due to evaporative loss, chemical degradation or incomplete recovery. Because water vapor permeates easily through these materials, it is important to store the sample in an area with low humidity. This will avoid changes in the sample, which could affect the accuracy of the analysis.
