The Geospect continuous mud logging chromatograph detects methane through n-butane in under two and a half minutes. It fits neatly into the Geospect mudlogging system's case. The Geospect gas chromatograph uses the "packed column" method to break out hydrocarbons. The chromatograph also uses air as carrier its carrier gas. First, gas from the well bore is pushed through the column with approximately five psi of air. When the gas exits the column it is runs across a catalytic bead sensor and produces peaks. The gases come out in the following order: methane, ethane, propane, iso-butane, and normal butane. The peaks are then analyzed by the Geospect software and recorded. The above described process continuously repeats itself.
