Gas Fed Permeation Tubes
Trace Source 57 Series refillable permeation tubes extend the range of analyte compounds available to include high pressure gases, such as O2, CO, CO2, CH4, C2H2, etc. The tubes are used in proprietary gas standards generators to blend dynamically ppm and ppb mixtures directly from the pure gas. Typically permeation tubes contain liquified analyte compound (and its vapor) as the permeate source. This limits the range of compounds available in permeation tubes. The tubes use a controlled pressure of the analyte vapor as the permeate source, allowing permeation tubes of very low boiling compounds. Dilutions from <103:1 to >109:1 can be achieved in a single step with these tubes. They are particularly useful for preparing trace mixtures containing atmospheric gases, light hydrocarbons, hydrides, and acid gases. They can also be used to dilute multi-component mixtures.
