Kommentar:        Dokumente deut./engl.

Durch das Beibehalten einiger der beliebtesten Ausstattungsmerkmale des Varian GC 3700 und durch zusätzliche Automatisierungsmöglichkeiten, steigert der Star 3600 CX mit seinen Multi-lnjektoren und Multi-Detektoren beträchtlich die Produktivität. Mit seinem größten und komfortabelsten Säulenofen in der Industrie ist der 3600 CX die Basis für spezielle Systeme, wie z.B. Gasanalysatoren. Die Möglichkeit, 2 automatische Probengeber 8200 CX gleichzeitig betreiben zu können, ermöglicht es, den Probendurchsatz zu verdoppeln .

Der Multi-Modus GC Star 8200 CX Auto­sampler mit automatisierter "Sandwich"- Injection vermeidet die wichtigste Ursache für Probendiskriminierung. Optimiert für die Spurenanalytik, für kleine Proben-volumina und geringste Probenverluste, ist er der beste Autosampler der Industrie. Eine dynamische Spülung eliminiert Probenverschleppung und Varians neuer AutoDrive ermöglicht automatische Probenaufgabe in unterschiedliche Injektoren und damit höheren Probendurchsatz mit nur einem GC.
