Profile: Toledo Mud Logging Service, Inc. specializes in mud logging services. Our gas detector is a total combustible hydrocarbon, monitoring system. The system uses two detectors, a catalytic bead sensor (CC) and a thermal conductivity sensor (TC). Each sensor has its own amplifier so that each sensor can be zeroed with no interaction with the other sensor. The gas detector has two outputs one to a strip chart recorder and the other to the data acquisition computer. Gas chromatograph is a combustible hydrocarbon identification system. It will detect and indicate the amounts of methane, ethane, propane, iso-butane and normal butane. The separation of the individual is accomplished with a coiled tube filled with special granules. The gasses, once separated are sent one at a time to a catalytic bead detector. The output of the detector is amplified and sent to the front panel indicator, a strip chart recorder and is available for connection to an integrator.
