Preprocessing is a critical step in the analysis pipeline of spectroscopic data. However, students are rarely introduced to preprocessing when learning spectral techniques in laboratory courses which in turn may affect and delay their progress in the field. Despite its undoubtable importance, students will be mainly performing spectroscopic…

It is crucial nowadays to predict in a fast and simple manner physical-chemical behaviors like, the size-dependent optical properties of gold nanospheres (Au NSs). The idea behind this experiment is trying to replace (as much as possible) robust and expensive microscopy techniques with UV-vis spectrophotometry and friendly simulations. Students…

An ICP-MS simulation was developed to support the teaching of inductively coupled plasma-mass spectrometry. The app enables students to conduct the quantification of selenium in a nutritional supplement, monitor the uptake of metallodrugs by cells, and perform qualitative analysis of gunshot residue. The experiments teach a range of analytical…

Ion channel sensors have several applications including DNA sequencing, biothreat detection, and medical applications. Ion channel sensors mimic the selective transport mechanism of cell membranes and can detect a wide range of analytes at the molecule level. Analytes are sensed through changes in signal patterns. Papers in the literature have…

In this paper, the development of an automatic assessor is presented, both in MATLAB and in Excel, for an analytical exercise. In particular, the emulation of an interlaboratory exercise, using the analytical determination of phosphorus in a dry detergent, carried out in the laboratory by different groups of students, was selected as a case of…

The pharmaceutical industry relies heavily on analytical techniques for identifying and characterizing drug compounds. In this experiment, undergraduate pharmacy students explored the applications of near-infrared spectroscopy for pharmaceutical analysis and its potential for identifying patterns and relationships among pharmaceutical samples. In…

How do cultural heritage scientists and art conservators identify pigments and other painting media in a decorated object or painting, preferably without taking samples that could potentially damage the artwork? A major emphasis in the characterization, authentication, and conservation of works of art and cultural heritage objects is the use of…

This exercise encompassed the construction and use of a microcontroller-based laser refractometer. The instrument, which does not require a high skill level to build, primarily consisted of a line laser, optical sensor, several 3-D printed parts and printed circuit boards, and a microcontroller development board. Construction and testing of the…
