How to Plot Multiple FTIR Data in GraphPad Prism

Introduction

Fourier Transform Infrared Spectroscopy (FTIR) is a widely used technique in scientific research to analyze molecular structures. When handling multiple FTIR spectra, visualizing them effectively is crucial. GraphPad Prism provides an intuitive platform for plotting and analyzing FTIR data with precision. In this tutorial, we will guide you through the process of plotting multiple FTIR datasets in GraphPad Prism and share additional resources such as FTIR file downloads and software links.

Why Use GraphPad Prism for FTIR Data?

GraphPad Prism is a powerful statistical and graphing tool, primarily used in biostatistics and research. Here’s why it’s suitable for FTIR data visualization:

• User-friendly interface for scientific graphing
• Advanced data analysis capabilities
• Customizable plots for professional presentations
• Seamless data import and organization

Steps to Plot Multiple FTIR Data in GraphPad Prism

Step 1: Prepare Your FTIR Data

Before plotting, ensure your FTIR data is properly formatted. Most FTIR spectra are provided in CSV, TXT, or Excel formats. You may need to convert them into a tabular format compatible with GraphPad Prism.

Step 2: Import FTIR Data into GraphPad Prism

1. Open GraphPad Prism.
2. Click on File > Import and select your FTIR dataset.
3. Ensure that your data is structured in XY format, where X represents the wavelength (cm⁻¹) and Y represents absorbance or transmittance.

Step 3: Create a Graph

1. Select XY Graph Type to display spectral data.
2. Choose “Scatter with Lines” to visualize multiple spectra simultaneously.
3. Assign different colors or styles to each dataset to differentiate them.

Step 4: Customize the Graph

• Adjust Axes Labels: Set X-axis to “Wavenumber (cm⁻¹)” and Y-axis to “Absorbance” or “Transmittance.”
• Apply Smoothing (if needed): Use the smoothing function under Graph Settings to refine your spectra.
• Add Legends & Titles: Clearly label each dataset to enhance readability.

Step 5: Export Your FTIR Plot

1. Click Export Graph and select your preferred format (PNG, TIFF, or PDF).
2. Optimize image resolution for publications or presentations.
