System to Prevent Clogging of Gas Sampling Tubes

Details

• Personal Author:

• Description:
  The Bureau of Mines utilizes special testing methods for the analysis of underground mine atmospheres for use during or after mine disasters and fires. These methods depend upon drawing sample gas to the surface through multiple tube bundles with the subsequent analysis of grab samples or the automatic analysis by often remotely located instruments on a continuous, 24-hour basis. This report covers research and resulting development conducted by the Bureau of Mines to produce a reliable method to selectively remove condensable vapors and particulate in the sample gas stream under worst-case field conditions. The effort resulted in two prototype systems that have greater field utility than originally anticipated. The innovative project resulted in two patent applications submitted through the Bureau of Mines. [Description provided by NIOSH]
