The Jordan Valley Legacy of Innovation Continues
For well over a decade XRF has been the preferred method for analyzing wood treating chemicals in the baths as well as monitoring the retention in the wood. Virtually every piece of treated lumber in the US has been certified based on XRF results. The American Wood Preservers Association (AWPA) has approved XRF methods for analyzing every common pressure-treating chemical. Here are several different types of treating processes that can be monitored by XRF.

CCA in Wood and Solution
Wolmanized lumber is treated with a chromium, copper, and arsenic (CCA) treatment. CCA treated wood is commonly used in decks. The concentrations are high and EDXRF can measure them easily.

ACZA in Wood and Solution
Chemonite (ACZA) treatment is an alternative to CCA, and contains ammonium, copper, zinc and arsenic. The last three can be measured by EDXRF.

ACQ in Wood and Solution
ACQ is yet another preservative it contain ammonium, copper and Quantenary ammonium. Total ACQ is quantified based on the Cu analysis.

Pentachlorophenol in wood and Solution
Pentachlorophenol is what is commonly used in telephone poles and railroad ties. It contains chlorine and can easily be monitor by EDXRF.

Zinc Borate treated wood and solutions
Zinc borate is a fungicide added to masonite and other types of composite and pressed wood.

IPBC treated wood and solutions
IPBC (3-iodo-2-propynyl butyl carbamate) is another insecticide product used to treat wood. It is often used in finished woods like window frames, and can be measured based on the iodine intensity. IPBC is particular good as a termiticide.

Bromine Wood Treatment
Some organic bromine compounds can be a good termiticide and can be analyzed with EDXRF.
