Abstract: A sampling apparatus is provided. The sampling apparatus may include at least a valve, a pump and an actuator. The valve may include a sampling channel, a transfer channel and an extraction channel. The pump may be connected to at least one of the transfer channel and the extraction channel. The actuator is operable to transition the valve from a sampling position to an extracting position. The sampling position includes a fluid connection between the sampling channel and the transfer channel and the extracting position includes a fluid connection between the transfer channel and the extraction channel.
