  • Patent number: 11360066
    Abstract: This invention is a gas standard preparation device and method of use for creating a reference material or a certified reference material. The reference material or the certified reference material is used to quantitate air from a collected sample. This is beneficial for identifying if the air within the area contains certain volatile compounds or other undesired compounds. This is accomplished by providing a sealed ampule containing reference material that is eventually broken by the gas preparation device. Once the ampule is broken, the reference material within the ampule is mixed with a diluent gas and forced into a reference material cylinder. The concentration of the final reference material within the reference material cylinder is verified for use in testing collected air sample. Accordingly, this device allows for creating a custom reference material onsite in a laboratory without the need for shipping in pre-made compressed gas cylinders for air quality testing.
