often the former is allowed to diminish while the spectrum is scanned. Each m/z ion from light toheavy is successively swept past the detector slit at a known rate. The detector current is amplifiedand displayed on a strip-chart recorder. Since the ion paths are separated from one another, therecord[r]

Natural products – Discover their challenge and beauty
Natural products have always been among the most fascinating objects of the
practicing chemist. In fact, in many definitions of chemistry the isolation, purifi
cation and structural elucidation of natural products plays a central role. The his

ngineering mechanics is the application of mechanics to solve problems involving common engineering elements.

The goal of this Engineering Mechanics course is to expose students to problems in mechanics as applied to plausibly realworld scenarios. Problems of particular types are explored in detail[r]
