METHOD FOR ANALYSIS OF TREATED WOOD AND TREATING SOLUTIONS BY X-RAY SPECTROSCOPY
This Malaysian Standard specifies a method for X-ray spectroscopic analysis of treated wood and treating solutions.
1.2 The method is applicable to the determination of elements of atomic number 11 orhig her that are present in significant quantities the wood (usually above 0.01 percent).
1.3 The specific elements covered in this method, and specified for use in preservative treatment of wood, are, with their atomic numbers, phosphorus, P(15); sulphur, S(16); chlorine, Cl(17); chromium, Cr(24); copper, Cu(29); zinc, Zn(30) and arsenic, As(33).
1.4 Energy dispersive and wavelength dispersive spectrometers cad both be used. The instructions for operating each type of spectrometer are provided by the manufacturer and are not described here.
NOTE. Attention is drawn to the requirement that operators of x- ray machines shall comply with the Radioactive Substances Act 1968 and subsequent regulations under it.
