NEX QC Applications



ACZA wood treatment


AppNote 1225: the measurement of ACZA treated wood and wood treatment solutions is demonstrated.

Background
Wood treatments are used to protect lumber from fungi, insects, UV damage and general wear. Common wood treatment formulations containing only Cu, CCA, Penta and ACZA. Ammonia Copper Zinc Arsenate (ACZA) is often used to treat wood species that do not easily retain other treatments, such as Douglas Fir. 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. Cu, Zn and As 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.




Analysis of copper in ore


AppNote 1457: the analysis of copper in ore is demonstrated, suitable for exploration and ore grade control at the mine site.

Background
Elemental analysis is crucial for screening samples at the mine site as well as throughout the processing of ores. During smelting, major and minor elements are also closely monitored in the ore, concentrates, slags and tails. Rigaku offers the NEX QC Series of analyzers to meet these analytical needs of the mining industry, both at the mine site and the smelter. Simple yet versatile, the NEX QC is transportable for mine site screening, rugged enough for the smelting operations, and powerful enough for work in a central lab. The NEX QC utilizes 50 kV direct excitation and a high performance semiconductor detector to provide excellent sensitivity in a low cost tool ideal for the analysis of ore materials.




Analysis of S, Ni, V and Fe in residual oil


AppNote 1293: the analysis of sulfur, nickel, vanadium and iron in residual oil is demonstrated.

Background
Residual oil is the low-grade oil that remains after the distillation and refining of crude oil. Residual oil, also called resid, has many uses, including in the blending of bunker fuel, as well as in the production of adhesives and asphalt. In some regions resid can be burned as a secondary fuel and may be further refined as a heating fuel. Characterization of the nickel and vanadium content is important for many reasons, chief among these is that nickel and vanadium are considered catalyst poisons and need to be removed prior to the cracking of petroleum crude or residual oils. Applied Rigaku Technologies meets the industry analytical need with the NEX QC series of EDXRF analyzers. Fast and simple, the NEX QC provides an ideal tool for monitoring the concentrations of nickel, vanadium and iron in resid, as well as the sulfur content.




Ash content in coal


AppNote 1378: the measurement of predicted ash content in unburned coal is demonstrated.

Background
Ash consists of the metal oxides and heavier elements that remain after burning removes the organic, gaseous and volatile components. Coal quality and pricing in part depends on the ash content of the coal, and so predicting ash in coal before burning is important in many areas of the industry. EDXRF offers a fast and simple low cost method of predicting the % ash content in coal before it is burned.






CCA wood treatment


AppNote 1175: the measurement of CCA treated wood and wood treatment solutions is demonstrated.

Background
Wood treatments are used to protect lumber from fungi, insects, UV damage and general wear. In recent years, the US EPA has asked for voluntary compliance to restrict the use of chromated copper arsenate (CCA), due to concerns of Cr and As leaching into soils. Lumber treated with CCA is used in a limited number of situations, such as in roofing shingles, permanent building foundations, and certain commercial applications. 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. Cr, Cu and As 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.




Chlorine (Cl) and sulfur (S) in cement


AppNote 1250: the analysis of chlorine (Cl) and sulfur (as SO3) in cement is demonstrated.

Background
Monitoring proper levels of chlorine is especially vital in producing cement. Soluble chlorine, most often CaCl2, can be added to concretes and cements as an accelerating agent for faster strength development or shorter setting times. However, the presence of chlorine in reinforced concrete can cause corrosion of the steel reinforcing material, possibly causing premature structural damage. Sulfur in cement is often monitored during the addition of gypsum to the mixtures. The sulfur content in part determines drying rates and strength, as well as the ability of the cement to dry under water. For these reasons it is vital to monitor and control both the chlorine and sulfur levels. To meet this analytical need, Rigaku offer a small, simple to use benchtop EDXRF system ideal for use along the production and QC processes in a cement plant.




Cr coating on aluminum


AppNote 1605: the measurement of chromium (Cr) conversion coating on aluminum is demonstrated.

Background
Aluminum and steel are often coated with a protective conversion coating, also called passivate or passivation coating, to prevent oxidation and corrosion of the base metal. Conversion coatings include Cr, Ti, V, Mn, Ni, or Zr. A phosphate coating may be applied as well to minimize wear on cutting tools and stamping machines. Aluminum is often coated use in aircraft parts, aluminum window frames and other similar industries where the aluminum is exposed to weathering. Steel for the automotive industry is typically first galvanized with a zinc coating before the conversion coating is applied. Protected steel is also used for outdoor sheds and other similar uses where steel is exposed to weathering. Conversion coating also help in the retention of paint for the final finished product.




CuO wood treatment


AppNote 1141: the measurement of CuO in treated wood and wood treatment solutions is demonstrated.

Background
Wood treatments are used to protect lumber from fungi, insects, UV damage and general wear. Lumber treated with copper or copper oxide is used in a variety of residential and commercial construction projects, including house and building foundations, fences, patio decks and playground playscapes. 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. Cu or CuO 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.
