This free online course on Mastering FTIR Spectrometer: Operation, Calibration, Troubleshooting and Maintenance begins with a clear description of the principles of the Fourier-Transform Infrared (FTIR) spectrometer, which is one of the most widely used analytical instruments in modern laboratories. It is valued for its ability to identify and characterise chemical substances with speed and accuracy. You will explore the key components of an FTIR spectrometer, including the source, interferometer, detectors, and sample accessories, and learn how these parts work together to generate high-quality spectra. Practical sessions will guide you through the correct handling of various sample types, including solids, liquids, and gases, and demonstrate how to select the appropriate sampling technique, whether using ATR, transmission, or reflectance. By the end of this section, you will have the foundation needed to confidently operate an FTIR spectrometer and understand the science behind its performance.

The course then moves on to essential laboratory practices that ensure accuracy and reliability in FTIR measurements. You will learn how to calibrate the instrument using recognised standards, assess performance with tests for resolution, wavenumber accuracy, and signal-to-noise ratio, and document results in line with industry requirements. Common problems encountered in routine analysis are addressed in detail, with step-by-step troubleshooting strategies for noisy baselines, weak signals, optical misalignment, and sampling errors. In addition, you will be introduced to best practices in maintenance, including cleaning, desiccant replacement, ATR crystal care, and preventive servicing, all designed to prolong instrument life and guarantee dependable results. These lessons combine theory with practical examples to build strong competence in both the operation and care of FTIR spectrometers.

What makes this course especially valuable is its emphasis on practical application across diverse scientific and industrial fields. Whether you are working in pharmaceuticals, food analysis, polymers, environmental testing, or academic research, the skills you will learn here will enable you to generate reliable data and solve real laboratory challenges confidently. The course also highlights regulatory and quality assurance perspectives, ensuring that your practice aligns with international standards and laboratory compliance needs. With its combination of clear explanations, hands-on procedures, and professional troubleshooting guidance, this training will give you the confidence to use FTIR effectively and maintain it for long-term performance.
