TECHNOLOGY FOCUS - CHEMICAL ENGINEERING - Preferred Carbon Material: The fluid is a liquid, gas, vapor and/or multiphase fluid. The carbon material does not emit water into the fluid. The carbon material is preconditioned to remove contaminants from a reactive fluid such as ammonia. The carbon material is a highly hard carbon material.Preferred Method: After maintaining the carbon material in non-contaminating environment, the carbon material is purged with an ultra-purified reactive fluid at room temperature for specific period of time. The carbon material is then heated at about 50-400degreesC for few hours to few days, such that the carbon material is transformed into a preconditioned carbon material. The carbon material is introduced into a container having gas inlet, gas outlet and a receiving port. The container is purged with an ultra-dry inert gas. A portion of the carbon material is transferred to the container along with the inert gas. The receiving port is closed while maintaining the flow of inert gas. The gas inlet and outlet are closed such that the carbon material is maintained in an ultra-dry inert atmosphere. Heating is terminated when the concentration of water in inert gas is about 10-100 ppb at ambient temperature. The carbon material is treated at about 500-700degreesC for 2-5 days. The container is adapted for use in a gas purifying system.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Contaminants: The contaminants include water, carbon monoxide, carbon dioxide or organic compounds. The organic compounds are straight chain or branched hydrocarbons, preferably hexane or n-butane, or aromatic hydrocarbons such as benzene or ethyl benzene. The concentration of the contaminants or the concentration of water in inert gas is measured by Fourier transform infra red spectrometry or atmospheric pressure ion mass spectrometry. The contaminants in the fluid are reduced to less than 1 part/billion. EXAMPLE - Advanced technology materials incorporated (ATMI) carbon beads (10 mL) were heated stepwise in a reactor over several days in an ultra-dry nitrogen atmosphere at a 2 slpm (standard liters per minute) flow rate, and the concentrations of moisture and carbon dioxide (CO2) in the exhaust stream were monitored by atmospheric pressure ion mass spectrometry (APIMS), which has a detection limit of about 10-100 parts-per-trillion (ppt). The initial levels of moisture in the exhaust gas at ambient temperature decreased slowly over several days. An increase of the activation temperature from room temperature to 110degreesC increased the amount of moisture in the exhaust gas stream by a factor of about 500. After cooling back to room temperature, the moisture level in the exhaust gas stream rapidly dropped to concentrations below that observed prior to heating. Further heating to 300degreesC and to 500degreesC resulted in an additional release of significant amounts of moisture (H2O) from the carbon material. After activation of the carbon at 500degreesC for five days, the moisture levels emitted into the exhaust gas stream at 500degreesC approached to concentrations observed in the exhaust stream at ambient temperature prior to the activation procedure, that is about 500-1000 counts per second (cps). After cooling to room temperature, the moisture response dropped to about 100 cps, indicating sub ppb moisture concentrations. The carbon dioxide emission followed similar trends to the moisture emission.
