Abstract
A flow chamber (10) for sampling drilling mud on a continuous basis comprises a rigid box (18) having an inlet (34) and an outlet (36). The box (18) is of rectangular cross-section which increases in depth and decreases in width from front to back to facilitate flow of drilling mud therethrough. A fitting (42) is provided in the top side of the box (18) for receiving a hydrocarbon sensor.
