Focused on advanced analytical chemistry, this workbook complements the Skoog/Holler/Crouch textbook, making it ideal for self-study. It covers key topics like mass spectrometry, nuclear magnetic resonance spectroscopy, and various electroanalytical methods, including potentiometry and voltammetry. Additionally, it explores specialized techniques such as radioactive substance analysis and fluorescence methods, while emphasizing the role of electrochemical and optical sensors. The course concludes with essential statistical principles relevant to analytics, supported by references and illustrations from the main textbook to aid independent learning.

This workbook is designed for self-study, summarizing and explaining the essential content of analytical chemistry based on Harris's work. It is divided into five parts, covering basic concepts and various techniques, including dimensional analysis and chromatography. The workbook discusses UV/VIS, infrared, and Raman spectroscopy for investigating molecular compounds, along with selected atomic spectroscopy techniques, providing a comprehensive introduction to analytical fundamentals. It frequently references essential sections and illustrations, promoting independent learning for undergraduate chemistry students or those in related fields. The text connects familiar concepts from general chemistry to new material, making the learning process more intuitive. Tested in a distance learning chemistry course, this workbook aids in preparation for module examinations in analytical chemistry. It is a translation of the original German edition by Ulf Ritgen, published by Springer-Verlag GmbH in 2019, utilizing artificial intelligence for translation, followed by human revision for content accuracy. Springer Nature is committed to advancing book production tools and technologies to support authors.

Der Gezeitensturm naht, während die Zwillingsplaneten Opal und Erdstoß ihrer Sonne näher kommen. Trotz des Einreiseverbots wagen einige Abenteurer den gefährlichen Weg nach Erdstoß, auf der Suche nach einer untergegangenen Zivilisation oder Verbrechern. Die Planetenverwalter Hans Rebka und May Perry müssen eingreifen.

Die Rubin-Dynastie, Erbherrscher des skolianischen Reiches, ist durch politische Intrigen getrennt. Im Schatten eines interstellaren Krieges versuchen sie, ihre Familie zusammenzuführen und ihre Position an der Spitze Skolias zurückzugewinnen, während viele Angehörige vermisst oder tot sind.

Living in exile on a deserted planet, Sauscony and Jaibriol, each the heir to an interstellar empire, become entangled in the machinations of the Skolian Empire. Interstellar war erupts and Jaibriol is snatched away to be the unwilling ruler of the Highton Aristos. Sauscony must lead an invading space fleet to rescue him from his own Empire-without revealing that they are married. With much of interstellar civilization poised on the brink of destruction, it is the devotion of these two lovers, their sacrifices, and their heroism, that might just forge a new order.

- A tale of the Ruby Dynasty/Skolian Empire. - Two interstellar empires are locked in seemingly endless conflict: the Skolian Empire, with its well-trained Jagernauts and faster-than-light communications maintained by members of its Ruby Dynasty, against the Eubian Empire, which thrives on slavery and whose elites are known for their cruelty. Soz Valdoria, a Jagernaut and member of the Ruby Dynasty, is attracted to her supposed "enemy" Jabriol, the son of the ruler of the Eubian empire, or Traders. With hostile forces seeking their capture or death, Soz and Jabriol must work out their own -- and hopefully their empires' -- salvation.

Im 23. Jahrhundert leben die Menschen friedlich in der Galaxis, doch ein gescheitertes Experiment hat ein gefährliches, bewaffnetes Wesen erschaffen. Ein Notfall-Team wird entsandt, um die Bedrohung auf einem unerforschten Planeten zu bekämpfen.

Phil Hastings führt ein glückliches Leben mit Erfolg und Familie, bis seine Söhne im Elfenhügel seltsame Geschöpfe entdecken. Ein harmloses Spiel wird ernst, als Hastings erkennt, dass seine Söhne vertauscht wurden.

In einer zukünftigen Erde unter Quarantäne glaubt eine pazifistische Alienrasse, die Menschheit sei gefährlich. Das Militär umgeht diese Quarantäne und beauftragt Chan Dalton, Vorfälle im Weltraum zu untersuchen. Er muss gewaltfrei handeln, stößt jedoch auf heftigen Widerstand, was die Aufhebung der Quarantäne gefährdet.
