Near infrared (NIR) spectroscopy is a rapid, flexible, inexpensive and non-destructive technology that has many applications, including the evaluation of many wood properties. Initial studies have indicated the potential to apply NIRS for the quantification of wood preservatives. However, further evaluation with borate and azole preservative systems has revealed that NIRS technology is challenged by the variability of wood and low preservative retentions. Quantification of certain wood preservatives for quality control purposes using NIRS does not appear to be practical at present.
