A sampling apparatus for sampling a fluid from a fluid source includes a first fluid passage device, a second fluid passage device and a fluid by-pass. The first fluid passage device is disposed downstream of and in fluid communication with the fluid source. The second fluid passage device is disposed downstream of and is in fluid communication with the first fluid passage device. The fluid by-pass is disposed downstream of the fluid source and upstream of the second fluid passage device. The fluid by-pass being in fluid communication with and disposed between the fluid source and the second fluid passage device is operative to cause a first portion of the fluid to flow through the first fluid passage device and to cause a second portion of the fluid to by-pass the first fluid passage device and to flow to the second fluid passage device.
