Shimadzu IR Solution FTIR Normalizing, Baseline Correction, Smoothing, Peak Pick and Area

Introduction

The video "Shimadzu IR Solution FTIR Normalizing, Baseline Correction, Smoothing, Peak Pick and Area" is a comprehensive guide to using the Shimadzu IR Solution software for Fourier Transform Infrared Spectroscopy (FTIR). The tutorial covers essential processes such as initializing the system, performing scans, and analyzing the data.

Main Points

1. Software Initialization:

- The video begins with instructions on launching the IR Solution software and initializing the FTIR machine. This is especially important for the first user of the day.

2. Background Scan:

- The presenter demonstrates how to perform a background scan, emphasizing that the machine should be free of any samples during this process. Parameters like the number of scans and the scan range are adjusted accordingly.

3. Sample Measurement:

- After placing the sample into the FTIR machine, the measurement process is initiated. The software processes the data scan, and once complete, the sample's spectrum is ready for analysis.

4. Data Processing Techniques:

- The tutorial covers several data processing techniques, including peak picking, baseline correction, and smoothing.

- Instructions are provided on adjusting noise levels, threshold, and minimum area for peak picking.

5. Manual Peak Editing:

- The presenter shows how to manually edit peaks to remove unwanted data points from the spectrum.

6. Baseline Correction:

- Baseline correction involves connecting the higher regions of peaks to set up a baseline. This process is shown step-by-step, illustrating how to select points and calculate the new spectrum.

7. Zooming and Printing the Spectrum:

- The video demonstrates how to zoom into specific parts of the spectrum and adjust the presentation for printing.

- A method is shown for copying the spectrum image to the Paint application, cropping, and preparing it for printing in an A4 landscape format.

Conclusion

This instructional video provides a detailed walkthrough of the Shimadzu IR Solution software, guiding users through various steps of FTIR analysis from initialization to printing the final spectrum. It is a valuable resource for anyone working with FTIR spectroscopy and seeking to understand the software's functionalities.
