ABSTRACT:
An apparatus is shown which prevents the intrusion of liquids into a gas chromatograph wherein a ball-check valve comprised of a flotation chamber and a spherical floatable valve element is positioned between and in fluid communication with an inlet and outlet port. While gasses are permitted to flow past the valve and into the gas chromatograph, liquids are retained within the flotation chamber by the floatable valve element. When the liquid level rises to a certain level within the chamber, the valve is closed by the pressure of the liquid forcing the floatable valve element into a closed and sealed position. The ball-check valve is also surrounded by a transparent member which allows the user to view the liquid level within the valve at all times.
