Sampling Valve for Gas Chromatography.
Abstract
A four-port glass valve for use in gas chromatography including a glass stopcock with a high vacuum grind. At its tapered end the stopcock plug is fitted with a threaded brass stud to accept a retaining ring and spring-loaded nut. Two sample loops are attached to the valve body by means of ball-socket joints to allow ready replacement with variable size loops. The valve is especially suitable for use with corrosive gases and is leakproof to at least 50 psig.
