Instrumentation plays a vital role in almost every area of chemistry. As such, it is imperative that the undergraduate curriculum is designed to allow students to have opportunities to use a variety of instruments to best prepare them for careers in chemistry. Previous work has provided evidence of the types of instruments students use in…

A low-cost turbidimeter, colorimeter, and nephelometer (TCN) multipurpose instrument applicable for undergraduate, graduate, and research laboratories is demonstrated within this work. The instrument relies on simple and robust electronics while using a PC sound card as an analog-to-digital converter. The performance of the instrument was…

The goal of this laboratory exercise was for students to understand the concept of chirality and how enantiomeric excess (ee) is experimentally determined using the analysis of ibuprofen as an example. Students determined the enantiomeric excess of the analyte by three different instrumental methods: mass spectrometry, nuclear magnetic resonance…

The teaching laboratory in physics departments in colleges and universities is a source of great potential strength in undergraduate education. Recent surveys and conferences, have identified inadequate teaching equipment and laboratory development. This report reviews these problems and offers suggestions for an enhanced federal effort to solve…

Outlines Marquette University's response to declining enrollments and financial restraints for its undergraduate biology curriculum, beginning with a description of the old program and its problems. Discusses redefinition of laboratory role, uncoupling and reducing number of laboratories required, teacher responsibility changes, centralized…
