Overview

An advanced lab experiment reveals glucose levels in Kombucha using chemometrics and statistical methods.

Key Points

  • This research aims to enhance students' understanding of chemometrics through a practical laboratory experiment.
  • Students compare two colorimetric methods for measuring glucose levels.
  • They use least-squares linear regression for statistical analysis.
  • An infusion of tea, glucose, yeast, and bacteria forms the batch system.
  • Samples are collected over a week and analyzed in a four-hour lab session.
  • A Matlab routine is used for statistical applications specific to analytical chemistry.
  • Students learn to identify constant and proportional biases in the methods.
  • The experiment effectively demonstrates the application of chemometrics in real-world scenarios.
  • Statistical software aids in understanding the data analysis process.
