Zusammenfassung:	A fluid sampling and analysis module for a downhole fluid characterization apparatus configured for operation downhole, within a borehole. The fluid sampling and 5 analysis module comprises a primary flowline for fluids withdrawn from a formation to flow through the fluid sampling and analysis module, a bypass flowline in fluid communication with the primary flowline and a single valve, interconnecting the primary flowline and the bypass 10 flowline, operable to a first position for formation fluids to flow in the primary flowline and to a second position for formation fluids to flow, via the bypass flowline, in the primary flowline.
