Description

This comprehensive and unique handbook of split and splitless injection techniques has been completely revised and updated. This new edition offers:

- New insights concerning sample evaporation in the injector
- Information about matrix effects
- A new chapter on injector design

The real processes within the injector are for the first time visualized and explained by the CD-ROM included in the book. Furthermore the reader will understand the concepts of injection techniques and get a knowledge of the sources of error. The handbook also includes many practical guidelines.

From reviews of former editions:

"This substantial book is on injection techniques alone, which ... demonstrates this can have many pitfalls ... no one should be allowed to direct a laboratory doing quantitative analysis by GC without first being thoroughly familar with this book ..."
The Analyst

"This is a detailed reference volume filled with practical suggestions and techniques for managing split and splitless injection in the day-to-day world of the working gas chromatographer. It will be useful ... for anyone who must work hands-on with GC."

Reviews

Aus Rezensionen zu früheren Auflagen:
"Das enorme Potential moderner Kapillarsäulen läßt sich nur in Verbindung mit einer geeigneten Dosiertechnik ausschöpfen. Im Vergleich zu anderen chromatographischen Methoden bieten die verschiedenen Dosiertechniken in der KGC einen breiten Spielraum, dessen problem- und probeorientierte Ausnutzung jedoch detaillierte Kenntnisse über die bei der Dosierung ablaufenden Prozesse erfordert. Genau dieses Ziel verfolgt der Autor K. Grob mit dem Buch... Es bleibt zu hoffen und zu empfehlen, daß recht viele Einsteiger und Fachkollegen ... die Zeit ... finden werden, dieses umfangreiche Werk oder wenigstens die entsprechenden Abschnitte ... durchzuarbeiten."
