A simple, low-cost, robust and easily fabricated dual flame thermocouple detector for gas chromatography has been developed. This detector is responsive to all combustible vapours, with a sensitivity of cu. 4\*10-8 and a noise level of 2. 1O-8 measured in terms of g-mole/set of propane.
This paper describes a modiiied form of the single jet flame ionization detector of MCWILLIAM ANI) DEW~\II~. The difference between the modified and the original form of the apparatus lies mainly in the electrical circuit of the amplilier. With the ampli-' fying circuits described below the modified
A new type of helium direct current plasma ionization detector (HeDCPID) for gas chromatography has been developed. The detector is simple in construction and can function with helium as the carrier gas without the need to subject the helium to excessive purification procedures. The noise level of t
