A Sentex model Scentograph GC can be configured for AID or ECD. Interfaced with the unit is a Toshiba model T 1100 lap top computer which runs the data acquisition program and stores all parameters and data. The Sentex unit has an internal battery pack which is charged from a Power Sonic Corp. model PSC-12400, (115 VAC to 12 VDC) charger. Attached to the T 1100 is a Hewlett-Packard model 2225P Think Jet printer. This produces hard copies of chromatograms and peak data information. No other equipment is required to operate the Sentex Scentograph unit.
