Topic of the Week
Absorption spectrophotometry is the workhorse of analytical chemistry.
Measurements are quick, accurate, safe, and inexpensive. Absorption
spectrophotometry is one of the top three lab topics in general chemistry.
Although spectrophotometry is based on color, it is almost always
taught with instruments that present a black-and-white graphical view of a
colorful, conceptual, and interesting science.
MicroLab can improve this situation. Our inexpensive Visual Spectrometer makes color and absorption spectra quickly come to life. MicroLab’s FASTspec™ scanning spectrophotometer software will engage your students with a full color view of each sample’s molecular absorption spectra. Students transparently convert observations to graphs and mathematical models. They can use this information to accurately measure solution concentration, reaction kinetics, turbidity, scatter, and fluorescence, and to conduct spectrophotometric titrations.
FASTspec™’s unique ability to make simultaneous measurement of transmission/ absorption spectra,
and scatter and fluorescence with multiple excitation wavelengths, encourages inquiry. Students can run a
standard Beer’s Law plot and then ask “Is there more to it?” There almost always is.
