What are the limitations of the IR spectroscopy? (5 Key Points)

IR spectroscopy is a powerful analytical tool, but it does come with several limitations that can affect the accuracy and reliability of the results.

What are the limitations of the IR spectroscopy? (5 Key Points)

What are the limitations of the IR spectroscopy? (5 Key Points)

1. Sample Preparation Issues

The quality of the IR spectrum is highly dependent on the proper preparation of the sample.

Issues such as insufficient grinding of the KBr mixture, improper drying of the sample, incorrect sample-to-KBr ratio, or a pellet that is too thick can lead to a cloudy or poor-quality spectrum.

These preparation errors can obscure or distort the peaks, making it difficult to interpret the data accurately.

2. Detection Range and Sensitivity

IR spectroscopy is sensitive to certain functional groups and may not detect all types of chemical bonds or elements.

For instance, it may not be as effective in detecting light elements or non-polar compounds.

Additionally, the detection range is limited by the linear response of the detector, which can cut off peaks with high intensity, leading to misinterpretation of impurities or major components in the sample.

3. Quantitative Analysis Limitations

IR spectroscopy is primarily used for qualitative analysis, identifying the types of bonds present in a molecule.

However, it is less reliable for quantitative analysis, which involves determining the exact amounts of components in a mixture.

This limitation arises from the difficulty in ensuring consistent sample preparation and the detector's linear response range.

4. Sample Form and Measurement Method

The effectiveness of IR spectroscopy depends on the appropriate selection of the measurement method based on the sample form.

While methods like diffuse reflection and attenuated total reflection (ATR) have expanded the applicability of IR spectroscopy, not all methods are suitable for every type of sample.

This requires careful consideration and sometimes multiple methods to obtain a comprehensive spectrum.

5. Environmental and Operational Constraints

Despite advancements in technology, handheld IR spectrometers still face physical limitations in terms of durability and operation in demanding environments.

These constraints can affect the instrument's performance and longevity, requiring careful handling and maintenance to ensure accurate and reliable data.
