For a list of our isotope-labeled gases (includes high-purity gases, calibrants, and mixtures), refer to our Stable Isotope-Labeled Gases catalog. These can be used in a variety of applications. Examples include breath tests, microelectronics, organic light-emitting diodes (OLEDs), nitrogen fixation, quantum computing, and in vivo labeling of plants. Please inquire if an alternate gas, label, or mixture is required to satisfy your research needs.

Frequently Asked Questions
When will a gas liquefy?
A liquefied gas is a gaseous substance at ambient temperature and pressure that undergoes liquefaction by pressurization and/or refrigeration. This process compresses the gas making it suitable for gas carriage. As these gases are typically flammable with inherent safety hazards, these must be handled with care and transported by a suitable gas carrier. Examples of gases that liquefy include ammonia, 1,3-butanediene, carbon dioxide, propane, and ethane.
How do you calculate the approximate pressure in a cylinder at 20°C?
For ideal gases, the pressure can be calculated using the combined gas law: P1V1/T1 = P2V2/T2. To solve for P, factor in the following known values: volume of cylinder (e.g., 3 L), volume ordered (e.g., 20 L), temperature (i.e., standard – 273 K, atmospheric – 293 K), and atmospheric pressure (i.e., 14.7 psi). This equation does not account for the nonideality of gases nor does it apply to gases that liquefy in the cylinder.
Which gases can be refilled?
Examples of gases that can be refilled are carbon dioxide, carbon monoxide, methane, and nitrogen.
