How to check the moisture content of wood without a meter

Introduction

A Fourier transform infrared (FTIR) spectroscopy is a powerful tool that can be used to measure the amount of water in wood. This information can be useful for a variety of purposes, such as determining the moisture content of wood for construction or woodworking projects, or for assessing the condition of wood in historical buildings or artifacts.

How does FTIR spectroscopy work?

FTIR spectroscopy is a non-destructive technique that measures the absorption of infrared radiation by a material. When infrared radiation is shone on a sample, some of the radiation is absorbed by the molecules in the sample. The amount of absorption is determined by the molecular structure of the sample. Water molecules have a strong absorption band in the infrared region of the spectrum, so the amount of water in a sample can be determined by measuring the absorption at this wavelength.

How to use FTIR spectroscopy to measure the moisture content of wood

To use FTIR spectroscopy to measure the moisture content of wood, a small sample of wood is placed in an FTIR spectrometer. The spectrometer shines infrared radiation on the sample and measures the amount of absorption at the water absorption band. The amount of absorption is then used to calculate the moisture content of the wood.

Benefits of using FTIR spectroscopy to measure the moisture content of wood

There are a number of benefits to using FTIR spectroscopy to measure the moisture content of wood. These benefits include:

  • Accuracy: FTIR spectroscopy is a very accurate method for measuring the moisture content of wood.
  • Non-destructive: FTIR spectroscopy is a non-destructive technique, so it does not damage the wood sample.
  • Fast: FTIR spectroscopy is a fast method for measuring the moisture content of wood. A measurement can be made in a matter of minutes.
  • Versatile: FTIR spectroscopy can be used to measure the moisture content of a variety of wood species.

Conclusion

FTIR spectroscopy is a powerful tool that can be used to measure the moisture content of wood. This information can be useful for a variety of purposes, such as determining the moisture content of wood for construction or woodworking projects, or for assessing the condition of wood in historical buildings or artifacts.
