a sample chamber coupled to the first fluid line via a second fluid line that receives the fluid from the first fluid line, wherein the first fluid line and the second fluid line receive contaminated formation fluid when the fluid extraction device initially extracts the fluid from the formation into the first fluid line; and a fluid removal device associated with the second fluid line, the fluid removal device receiving at least a portion of the contaminated formation fluid from the second fluid line. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein the fluid removal device includes at least one carrier for collecting the contaminated formation fluid from the second fluid line. ### Claim 3 (depends on 2) The apparatus of claim 2, wherein the fluid removal device includes a plurality of carriers that receive fluid from the second fluid line in a selected sequence. ### Claim 4 (depends on 3) The apparatus of claim 3, wherein the selected sequence includes at least one carrier receiving the contaminated formation fluid from the second fluid line before the sample chamber receives the fluid from the second fluid line. ### Claim 5 (depends on 3) The apparatus of claim 3, wherein at least one carrier receives the fluid from the second fluid line after the sample chamber receives the fluid from the second fluid line. ### Claim 6 (depends on 1) The apparatus of claim 1, further comprising a flow control device associated with the sample chamber for supplying the fluid from the second fluid line into the sample chamber. ### Claim 7 (depends on 1) The apparatus of claim 1, wherein the fluid extraction device includes a pump that supplies the fluid from the formation under pressure into the first fluid line. ### Claim 8 (depends on 1) The apparatus of claim 1, wherein the sample chamber includes a back pressure device that causes the sample chamber to receive the fluid from the second fluid line against a selected pressure. ### Claim 9 (depends on 8) The apparatus of claim 8, wherein the selected pressure is one of: pressure generated by a compressed gas; and hydrostatic pressure. ### Claim 10 (depends on 1) The apparatus of claim 1, further comprising a sensor associated with the fluid extracted from the formation that determines a contamination level in the fluid extracted from the formation. ### Claim 11 (depends on 10) The apparatus of claim 10, wherein the sensor includes an optical device. ### Claim 12 (depends on 8) The apparatus of claim 8, further comprising a controller that controls a supply of the fluid from the second fluid line into the sample chamber. ### Claim 13 (depends on 1) The apparatus of claim 1, wherein the fluid removal device further includes a check valve that opens to enable the fluid removal device to receive the contaminated formation fluid from the second fluid line when the pressure in the second fluid line is above a selected pressure. ### Claim 14 A method of obtaining a sample from a formation, comprising: conveying a tool into a wellbore that includes a first fluid line for receiving fluid extracted from a formation and a sample chamber coupled to the first fluid line via a second fluid line that receives the fluid from the first fluid line when the fluid from the formation is extracted into the first fluid line; extracting the fluid from the formation into the first fluid line and the second fluid line; supplying the fluid from the second fluid line into a fluid removal device; and supplying the fluid from the second fluid line into the sample chamber after supplying the at least a portion of the fluid from the second fluid line into the fluid removal device. ### Claim 15 (depends on 14) The apparatus of claim 14, wherein supplying the fluid into the fluid removal device includes supplying the fluid to a plurality of carriers in a selected sequence. ### Claim 16 (depends on 15) The method of claim 15, wherein the selected sequence includes at least one carrier receiving the fluid from the second fluid line after the sample chamber receives the fluid from the second fluid line. ### Claim 17 (depends on 14) The method of claim 14, further comprising determining a contamination level in the fluid extracted from the formation and supplying the fluid from the second fluid line to the fluid removal device and the sample chamber when the contamination level is below a selected level. ### Claim 18 (depends on 14) The method of claim 14, further comprising controlling the supplying of the fluid into the sample chamber by a controller located at one of: in the tool; at a surface location; and a combination of controllers located in the tool and a surface location. ### Claim 19 (depends on 14) The method of claim 14, further comprising supplying the fluid from the second fluid line into the sample chamber against a pressure that is generated by one of: a pressurized gas; and hydrostatic pressure. ### Claim 20 (depends on 14) The method of claim 14, wherein the fluid supplied from the second fluid line into the fluid removal device is supplied via a check valve. ### Claim 21 (depends on 14) The method of claim 14, wherein extracting the fluid from the formation includes: sealing a probe against the formation; extracting the fluid from the formation by a pump into the first fluid line; and discarding the fluid extracted from the formation until a contamination in the fluid extracted from the formation is above a selected level.
