  • Pulsed electron attachment conductivity detector and carcinogen monitor for liquid chromatography
    Patent number: 4224566
    Abstract: This is a highly sensitive detection system to be used in conjunction with liquid chromatography to determine the extremely fast rates of electron attachment to electrophilic compounds in nonpolar solvents. The system integrates pulse radiolysis, liquid state electronics and liquid chromatography and is designated Pulsed Electron Attachment Conductivity-Liquid Chromatography or PEAC-LC. The detector system is responsive only to electrophilic compounds. Since electrophilicity has been correlated with carcinogenicity, the PEAC-LC detector system is a primary screening monitor for carcinogens.
