Abstract
A gas transfer system for transferring gas into an analytical instrument for isotope ratio analysis comprises a capillary for delivering sample and/or reference gas from a gas source, a first connector for connecting the capillary to the gas source, a second connector for connecting the capillary to the analytical instrument, a crimping device, wherein the internal surface of the capillary comprises a coating material to prevent or minimize adsorption of water to the surface. Also provided is a device for regulating gas flow in a gas inlet system of an analytical instrument, comprising a body member having an internal gas flow channel, and a clamping member for attachment to the body member such that when the clamping member is tightened onto the body member, the internal gas flow channel is adjustably and reversibly crimped, to adjust gas flow therethrough.
