PENTA wood treatment

AppNote 1203: the measurement of pentachlorophenol (PENTA) in treated wood and wood treatment solutions is demonstrated.

Background

Wood treatments are used to protect lumber from fungi, insects, UV damage, water damage and general wear. Pentachlorophenol (called Penta or PCP) is typically not used to treat wood used for residential application; however, it is used for heavier more industrial applications like treating telephone poles or materials for bridges. When treating wood, the proper balance of treatment solution must be monitored to ensure the highest quality while minimizing waste and excess cost due to treatment usage or product rejection. Penta levels are monitored in solution prior to treatment, and then in the wood to ensure proper retention. A quick, simple, reliable means of analysis is required throughout the quality control process. XRF is an ideal tool for such analysis.
