Liquid-interfaced oscillating glow discharge detector for a flowing liquid system.
A new liquid-interfaced oscillating glow discharge detector having a frequency and current response to femtomole and picomole quantities respectively of potassium nitrate and sucrose injected into an aqueous flowing eluent is presented. The glow discharge is formed in an argon atmosphere at ambient pressure between a platinum anode and a cathode consisting of an aqueous conducting solution. A detailed description of the appearance of the liquid-interfaced glow discharge at various electrode distances and the occurrence of high-frequency oscillations is given.
