Lesson order

  1. 1 of 10 · 28–34 min · Beginner–Intermediate

    Introduction to Analytical Chemistry

    Learn how analytical chemists identify, measure, validate, and interpret chemical substances using sampling, calibration, quality control, and complementary analytical techniques.

  2. 2 of 10 · 36–44 min · Intermediate

    High-Performance Liquid Chromatography (HPLC)

    Understand how HPLC separates peptide mixtures, how the instrument works, how chromatograms are interpreted, and how method variables affect resolution, retention, and peak shape.

  3. 3 of 10 · 38–46 min · Intermediate–Advanced

    Liquid Chromatography–Mass Spectrometry (LC-MS)

    Learn how LC-MS combines chromatographic separation with ionization and mass analysis to confirm peptide identity, characterize impurities, and investigate degradation products.

  4. 4 of 10 · 40–48 min · Intermediate–Advanced

    Analytical Method Validation

    Understand how laboratories demonstrate that analytical procedures are fit for purpose through accuracy, precision, specificity, linearity, range, robustness, detection capability, and documented validation.

  5. 5 of 10 · 30–36 min · Intermediate

    System Suitability Testing

    Learn how system suitability verifies current analytical readiness through resolution, precision, retention, efficiency, peak symmetry, and documented pass-fail criteria before sample analysis.
