CM2142 Analytical Chemistry 1
Introduction to data treatment and analysis; discussion on sample treatment and extraction, and sample preparation techniques, separation science, electrochemistry. Topics covered will be selected from: liquid extraction and solid phase extraction, some novel extraction technologies; comparison of traditional and modern extraction procedures; introduction to chromatography, with special emphasis on planar chromatography; introduction to electroanalytical methods.
Chemical/biochemical pocket companion designed by the editors of Current Protocols. Choose from a list of all of the commonly used biological buffer systems, enter your desired volume, pH, and buffer concentration, as well as the concentrations of your stock solutions of the conjugate acid and base, and the calculator will inform you of the exact volumes of these stock solutions to mix in order to obtain the buffer needed.
Fast and easy GC pressure and flow calculations at your fingertips. This portable version of the GC pressure/flow calculator can be used to instantly and accurately determine pressures and flows through open tubular capillary columns.
The LC Calculator quickly calculates flow rate and back pressure under a variety of conditions and column dimensions. The Back Pressure Calculator helps to determine what column configurations will work within your system's pressure range. Whereas the Flow Rate Calculator helps to find the column flow rate generated at your desired system back pressure.

Chemistry Toolbox is an app that provides quick access to the main data in chemistry within easy reach. The functionalities that are present are: periodic table, a few calculation tools for solution preparation, physical and chemical constants, pH indicators, NMR related information, data for common solvents, pKa information, amino acids, standard reduction potentials and organic functional groups.
The Galvanic Cell application provides the users with several experiments on electrochemistry. This app will help chemistry students to find the electric potentials or combination of substances based on the selection and the inputs from the user. With up to 73 different half-cell equations, the users can acquire an understanding of electrochemistry through analysis of many different redox experiments and can prepare for an actual lab experiment using the app. In addition, the app simulates experiments with animations of electron flow, indicating the specific electrodes and electrolytes. After identifying the substances within the cell and their half-cell reactions, the app can calculate the standard and actual potential using the Nernst equation.
