LabVIEW for Analytical Chemistry

Created by Mark Jenson at Concordia College, this site, currently in the ASDL Collection, provides two useful resources for instructors and students of analytical chemistry. The first is a collection of LabVIEW virtual instruments (VIs) for demonstrating topics such as signal-to-noise ratios, boxcar and ensemble averaging, power spectra, digital filtering, analog-to-digital conversions, and the Nyquest frequency.…

The End Creek Water Monitoring Project

Lab-in-a-Box: A Guide for Remote Laboratory Instruction in an Instrumental Analysis Course

Hands-on learning in a remote laboratory environment. This Journal of Chemical Education Article by Deon T. Miles and William G. Wells of the Department of Chemistry, Sewanee: The University of the South describes a homemade kit with at home, hands on laboratory experiments in spectroscopy and chromatography. The paper and supporting information describe both hands on…

HPLC Simulation Using Excel Macros

The simulation of important concepts in HPLC is accomplished through the use of provided Excel macros. The exercise is written with explicit instructions that can be used as an at-home laboratory exercise or as supporting material for lectures on chromatograpic theory. Macros are included for isocratic, linear and step gradient, and non-ideal behaviors (Langmuir, adsorption at…

Print, Build and Use Your Own LED Photometer

Low cost instrumentation for at Home or In Lab Experiments for Chemistry and Biology Laboratories These are instructions and 3D print files to construct a visible photometer using low-cost electronics for a cost of approximately $10, which includes $6.50 for a multimeter. The documents below have been written so you can "cut and paste" the…
A syringe with clear liquid on a digital scale

Gravimetric Acid-Base Titration

This analysis is designed to replicate the classic acid-base determination of an unknown titration, but using household chemicals as the standard, titrant, indicator, and unknown. Notably this analysis employs a digital scale and syringes in the place of pipettes and burettes, making this a unique gravimetric approach to acid base titrations.

A Beginner’s Guide to Microsoft Excel Spreadsheets and Graphs

Two tutorials on spreadsheets, equations, graphs and trendlines This post contains two Microsoft Excel tutorials. The first one shows some basics of Excel spreadsheets, such as equations and formatting. The second one shows how to make an x-y scatter plot and trendline on Microsoft Excel. Sample data is also provided so students can apply what they…
