Spectroscopy Based on Absorption

 Spectroscopy Based on Absorption

Historically, the first spectroscopic studies involved characterizing the emission of visible light from the sun, from flames, and from salts added to flames. Our survey of spectroscopy, however, begins with absorption because it is the more important technique in modern analytical spectroscopy.

1. Absorbance of Electromagnetic Radiation

2.Transmittance and Absorbance

3. Absorbance and Concentration: Beer’s Law

4. Beer’s Law and Multicomponent Samples

5. Limitations to Beer’s Law

The Analytical Perspective

Image
  The Analytical Perspective Having   noted   that   each   field   of   chemistry   brings   a   unique   perspective   to   the   study of   chemistry,   we   now   ask   a   second   deceptively   simple   question.   What   is   the   “analyt- ical   perspective”?   Many   analytical   chemists   describe   this   perspective   as   an   analytical approach   to   solving   problems. 7   Although   there   are   probably   as   many   descriptions of   the   analytical   approach   as   there   are   analytical   chemists,   it   is   convenient   for   our purposes   to   treat   it   as   a   five-step   process: ·       ...

Modern Analytical Chemistry: Introduction

  Introduction C hemistry   is   the   study   of   matte r ,   including   its   composition, structure,   physical   properties,   and   reactivity.   There   are   many   approaches to studying chemistry, but, for convenience, we traditionally   divide   it   into   five   fields:   organic,   inorganic,   physical, biochemical,   and   analytical.   Although   this   division   is   historical   and arbitrary,   as   witnessed   by   the   current   interest   in   interdisciplinary   areas such   as   bioanalytical   and   organometallic   chemistry,   these   five   fields remain   the   simplest   division   spanning   the   discipline   of   chemistry. Training   in   each   of ...

Preparing Solutions of Analytical Chemistry

Image
  Preparing Solutions Preparing   a   solution   of   known   concentration   is   perhaps   the   most   common   activity in   any   analytical   lab.   The   method   for   measuring   out   the   solute   and   solvent   depend on   the   desired   concentration   units,   and   how   exact   the   solution’s   concentration   needs   to   be   known.   Pipets   and   volumetric   flasks   are   used   when   a   solution’s   concen- tration   must   be   exact;   graduated   cylinders,   beakers,   and   reagent   bottles   suffice   when concentrations   need   only   be   approximate.   Two   methods   for   preparing   solutions   are ...
