Unit I: Instrument and Analysis Fundamentals

Experimental data are the results of direct or indirect observations of phenomena.  Good experiments are planned out using the scientific method. But how do we know if an experiment is reproducible?  This is really an essential question about every single experimental observation that must be answered, but is often not addressed, even by some good scientists who know better than to leave it to assumptions!

1. Data Analysis

2. Goodness of fit

Regression is a type of analysis in which the relationship between one or more independent variables and another variable, called the dependent variable, is modeled.

Unit III: Separations

The next step in qualitative and quantitative analysis is to identify samples that contain multiple species in varying concentration. This often requires coupling spectroscopic or electrochemical techniques with the capability of separating the sample mixture into constituent components. Hence the development of Chromatography and Electrophorsis, two of the most ubiquitous analytical techniques so far developed.

Unit II: Probing Matter with Light

Spectroscopy is the study of the absorption and emission of electromagnetic radiation by matter. Spectroscopy is an important tool that can be used to find the molecular structures, composition, and vibration frequencies of a substance. It can also be used to find the concentrations of reactants as functions of time to find the reaction intermediates. The defining characteristic of spectroscopy is the interaction of light (electromagnetic spectrum) and matter. Knowledge of both is required to fully interpret the measured data.

Unit IV: Electrochemical Techniques

Cyclic voltammetry is an electrochemical technique which can be used for both quantitative and qualitative analysis and can also be applied to the study of the kinetics and mechanism of the electrode reaction giving rise to the electro-analytical current signal. This technique is performed by cycling the potential of a working electrode, and measuring the resulting current.
