FTIR is an analytical instrument used to analyze the infrared spectrum of a sample. Infrared spectroscopy is a technique that measures the interaction of infrared light with molecules in a sample, providing valuable information about the chemical bonds and functional groups present in the material.

Key features of the LI-5500 may include:

• High sensitivity: The instrument is capable of detecting trace levels of gases with high precision, making it suitable for atmospheric monitoring and research.
• Wide spectral range: The LI-5500 covers a broad range of infrared wavelengths, allowing for the analysis of various gas molecules present in the atmosphere.
• Real-time monitoring: It may have the capability to provide real-time data acquisition and analysis, enabling researchers to observe changes in gas concentrations over time.
• User-friendly interface: The instrument likely comes with software that offers a user-friendly interface for controlling the spectrometer, collecting data, and performing data analysis.
• Robust construction: Designed for use in environmental field studies, the LI-5500 may feature a rugged construction to withstand harsh outdoor conditions.
