What This Document Is
This is a lab report submitted by Yana Leichyk for CHE 320, Instrumental Analysis at John Jay College of Criminal Justice. The report details an experiment focused on infrared (IR) spectroscopy and various sample preparation techniques. It was completed on November 22, 2021, and received a perfect check-out grade of 5/5.
Why This Document Matters
This report is valuable for students who have completed or are preparing for the same IR spectroscopy lab. It demonstrates a student’s understanding of the principles behind IR spectroscopy, the practical application of different sample preparation methods (KBr pellet, thin film, and mulls), and the ability to interpret spectral data. It serves as an example of expected lab report format and content for this course.
Common Limitations or Challenges
This document is a single student’s work and represents one interpretation of the experiment. It does not substitute for attending the lab, understanding the underlying theory, or completing the assignment independently. It is a specific instance, not a comprehensive guide.
What This Document Provides
The full report includes: a statement of the experiment’s aim, a brief overview of IR spectroscopy principles, a chemical waste table, instructions for instrument calibration, detailed procedures for three sample preparation techniques (KBr pellet, thin film salt plate, and mulls), and preliminary observations and data including a polystyrene reference spectrum. This preview only provides a summary of the report’s contents and context. It does *not* include the full experimental data, spectral analysis, or detailed conclusions.
