Description
Agilent 7890A GC with ECD & 7683 Autosampler Overview
Agilent 7890A GC with ECD & 7683 Autosampler is a GC system configured with a Split/Splitless (SSL) inlet, G2397A Micro-Electron Capture Detector (ECD), and 7683 Series Autosampler for automated detection of halogenated and other electron-capturing compounds.
The ECD uses a sealed 15 mCi Nickel-63 source to generate a steady electron stream. As electron-capturing compounds pass through the detector cell, they absorb electrons in proportion to their concentration, producing a signal used to detect and quantify organochlorine pesticides, PCBs, and similar halogenated analytes at trace levels.
The 7683 Autosampler holds up to 100 vials with a tray or 8 vials on a high-density turret, with injection volumes from 0.1 to 50 µL and reproducibility under 0.5% RSD for 1 µL injections. Pre- and post-injection syringe rinsing with two wash solvents reduces sample carryover, and injector drive uses electronic motor actuation with position feedback, requiring no periodic mechanical adjustment.
The SSL inlet uses a Turn-Top design for tool-free liner changes in under 30 seconds. 5th-generation Electronic Pneumatics Control (EPC) holds pressure setpoints within 0.001 psi.
