1. 1 Das Wesen der Analytischen Chemie Was ist Analytische Chemie? Analytische Chemie ist der Zweig der Chemie, der sich mit der Trennung und der Analyse chemischer Substanzen befaBt. Traditionell hat sich die Analytik weitgehend mit Trennungen und mit der Bestimmung der chemischen Zusammen- setzung befaBt. Die Entwicklung fiihrt jedoch mehr und mehr dahin, auch die Be- stimmung der chemischen Struktur und die Messung physikalischer Eigenschaften einzubeziehen. Die Analytische Chemie umfaBt sowohl die qualitative als auch die quantitative Analyse. In der qualitativen Analyse wird untersucht, was vorhanden ist, in der quantitativen Analyse, wieviel davon vorhanden ist. Das vorliegende Buch befaBt sich nahezu ausschlieBlich mit der quantitativen Analyse. Es scheint jedoch angebracht, kurz auf die qualitativen Methoden einzugehen, die zur Identifizierung der in einem Gemisch vorhandenen Substanzen benutzt werden. Der systematische qualitative Schwefelwasserstoff-Trennungsgang ist niitz- lich zum Kennenlernen und Durchfiihren einer Reihe von chemischen Reaktionen, wird in der Praxis jedoch kaum noch als analytische Methode angewandt. Die Emis- sionsspektroskopie (Kapitel 24) ist eine schnelle und brauchbare Methode, urn die in einer anorganischen Probe vorhandenen Elemente festzustellen. Fiir den Nach- weis vieler Ionen und Molekiile sind empfindliche und selektive Tiipfelreaktionen ausgearbeitet worden. Auch die Chromatographie ist eine sehr niitzliche Methode zur Trennung und zum Nachweis sowohl organischer wie auch anorganischer Sub- stanzen (Kapitel19-22). Zum Beispiel wurden Papier-und Diinnschichtchromato- 1 graphie angewandt, urn schnell Blutuntergruppen zu bestimmen und urn in Polizei- laboratorien die vielen in Kugelschreibern verwendeten Tinten zu identifizieren.

Many successful people find themselves at point in their life where they know it's time to make a major change. Most likely, they know what that change is, yet somehow find themselves unable to make the leap. They are creative and smart but find themselves off track or trapped by their own success, not knowing how to make the changes they deeply desire. Life coach, Jesse Gros, shares his story of the challenge to get out of his head and into his heart to create a life that had been waiting for him on the sidelines for almost two decades. He shows readers how to access their inner wisdom, and motivation to follow their true path. Jesse's voice, charisma and energy come through in his writing. He shares his journey over the last 20 years, including leaving medicine and walking away from corporate America. It includes stories about courageous clients and inspirational people he has met along the way. You will meet Jill S. who left her career and became a National Geographic photographer; David Rollins, who raised $5 million to start a non-profit; and Briana who had a surprise life-changing discovery while on retreat in Peru. Jesse shares with you his key learnings about how he built Insight Adventures - his life coaching and international retreat business in the middle of a recession, with no prior experience. You will read travel stories from Nepal, India and around the world. Also included are very personal stories about healing from both his life and from clients who have graciously agreed to let him share their experiences. This is a book about the inner and outer journey of life. Filled with joy, compassion, and self-discovery, "Your Wild & Precious Life" is a mind-opening tour of a nontraditional approach to living a heart-centered life.
