In this work, we designed and developed a method to detect S1 spike protein of SARS-CoV-2. The portable Localized Surface Plasmon Resonance instrument equipped with a two-channel system was combined...
The ability of students to perform quantitative analysis
is a fundamental
aspect of analytical chemistry courses and laboratories. In this laboratory
experiment, students quantitatively analyze both liquid and solid
samples through the use of internal standard calibration and ATR-FTIR
spectroscopy. Using a problem-based approach to selecting their internal
standards, students gain a deeper understanding of the internal standard
method of calibration and the process of selecting appropriate standards
for the analysis of sodium benzoate and acetophenone. This experiment
allows students to explore the internal standard method of calibration
under a wider context of quality control and quality assurance as
they frame their quantitative analyses through both internal and external
quality assurance testing methods. In a survey of students undertaking
this experiment, most students responded that the experiment provided
them with a better understanding of the internal standard method of
calibration, and the selection of internal standards, and offered
them an opportunity to gain hands-on experience with ATR-FTIR spectroscopy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
