Sommario/riassunto |
|
This book sets out to examine what really is going on in the organic sector socially and politically. In the process, it debunks a number of apparently common-sense beliefs: that organic consumers are wealthy environmental and health extremists; that growth in the industry will inevitably undermine its environmental values; that mainstream media is antagonistic to organics; and that the industry is driven by consumer demand. This book seeks to make a practical contribution to the development of more sustainable food systems by articulating what it takes to get people involved in organics at each stage of the food chain.. |

Sommario/riassunto |
|
This guide provides, under one cover, a wealth of practical information designed to facilitate the effectiveness of the GC/MS user. Separation conditions for numerous compound types are provided along with derivatized and underivatized compounds. A section on how to interpret mass spectral data, an extensive correlation of ion masses and neutral losses with possible structures, and examples of mass spectra are provided to further aid structure determination. Also included are basic information on instrumentation, ionization methods, quantitation, and tips on the operation of mass spectrometers. |
