Our free Spectral Analysis app makes it easy to incorporate spectroscopy into your biology and chemistry labs. Using the app, students can collect a full spectrum and explore topics such as Beer’s law, enzyme kinetics, and plant pigments.
The user-friendly interface walks the students through the data-collection process and includes analysis features such as curve fitting and data interpolation.
See sample experiment downloads, a list of supported instrumentation, and instructional screencasts.
Features
- Follow on-screen instructions for simplified Beer’s law or kinetics data collection.
- Collect full spectrum absorbance or % transmittance data in less than one second.
- Analyze data with built-in analysis tools, including data interpolation and curve fittings.
- Determine the order of kinetics reaction with the calculated columns function.
- Understand color transmission using the color strip shown on full spectrum graphs.
- Use Advanced Full Spectrum Mode to teach students the direct relationship between absorbance and % transmittance or observe a Stokes shift.
