\nAllScan\u00ae<\/span><\/h2>\n
The AllScan\u00ae analyzer combines state-of-the-art nuclear technology with ground-breaking spectra modelling and powerful statistical analysis. Installed on a conveyor belt, the AllScan\u00ae delivers accurate, minute-by-minute elemental analysis and reporting of the chemical composition of bulk materials and key process parameters.<\/p>\n

<\/p>\n<\/div><\/div><\/div>\nAt the heart of the AllScan\u00ae is PGNAA \u2013 prompt gamma neutron activation analysis. Material on the conveyor is bombarded with neutrons emitted from a radioactive isotope.\u00a0When neutrons collide with an element in the material, gamma rays are emitted with a specific energy unique to that element \u2013 in effect, creating a chemical signature for that element. The greater the amount of an element in the material the greater the number of gamma rays emitted with the corresponding specific energy. By measuring the specific energy of the gamma rays that are emitted and the counts of gamma rays, an accurate analysis of the chemistry of the material is generated on a second by second basis.<\/p>\n
RTI has taken this tried and proven technology and made it better \u2013 much more accurate, easy to install, calibrate, set up and maintain. AllScan\u00ae incorporates a unique analytical calculation concept called Dura-G\u2122.<\/p>\n
A well-known challenge with the PGNAA technology is a highly complex raw spectrum comprising of all the individual elemental spectra plus significant \u201cnoise\/disturbance factors\u201d from sample presentation, material depth variations, hydrogen signal etc. These factors make up the \u201cpresentation effects\u201d and can often be stronger than the \u201ccomposition effects.\u201d Dura-G\u2122 is a unique modelling and calculation concept based on sophisticated algorithms that separate the effect of environment, belt load and profile variations on the measured spectra from the effect of elemental variations.<\/p>\n
Thus, by smart removal of \u201cnoise components\u201d from the complex raw prompt gamma spectrum, Dura-G\u2122 creates a cleaned-up spectrum, which:<\/p>\n
- \n
- considers all the spectral components independently and ensures these components are correctly allocated to the separate composition and material presentation effects<\/li>\n
- increases the signal to noise ratio of the measured compositional signal and improves the deconvolution of same to provide output data with reduced measurement error compared to the traditional raw spectrum<\/li>\n
- supports a sophisticated sample free calibration methodology to provide an elemental analyzer that is not dependent on material or ongoing calibration techniques<\/li>\n<\/ul>\n
The Dura-G\u2122 technology smartly separates the composition and presentation effects, allowing all the spectral components of the complex prompt gamma spectrum to be correctly allocated to composition or presentation effects. In the processing, the significant noise attributable to hydrogen is also eliminated. The illustration below outlines how the unique AllScan\u00ae concept differs from the conventional calculation concept used by other players in the market.<\/p>\n

<\/p>\n<\/div><\/div><\/div>\nAllScan\u00ae also includes a powerful algorithm \u2013 DuraSum\u2122 \u2013 that eliminates the need for time-based averaging of data to obtain stable results. This means that changes in elemental composition of the material are reported almost instantaneously, rather than many minutes later. This in turn allows for rapid operational control.<\/p>\n

<\/p>\n<\/div><\/div><\/div>\nThe AllScan\u00ae online elemental analyzer arrives fully factory calibrated. It normally takes less than a day to mount to the conveyor stringers and connect to the plant DCS. In less than two days, accurate verifiable results are available as discrete digital signals for automated control of equipment and manual decision making. It can be custom configured to measure the elements in the periodic table of relevance to the user. Typical elements measured include:<\/p>\n
- \n
- Iron (Fe)<\/li>\n
- Aluminium (Al)<\/li>\n
- Silicon (Si)<\/li>\n
- Potassium (K)<\/li>\n
- Sulfur (S)<\/li>\n
- Calcium (Ca)<\/li>\n
- Magnesium (Mg)<\/li>\n<\/ul>\n
AllScan\u00ae also provides real time proximate and ultimate analysis including:<\/p>\n

\nAllScan\u00ae Coal<\/h2>\n
The AllScan\u00aeprovides real time\u00a0analysis of elemental composition that is used to improve monitoring, sorting and blending operations in coal fired power stations. AllScan\u00ae is used for the applications of raw coal, plant feed, clean coal and blended coal. AllScan\u00ae is the most affordable, accurate and easy-to-install cross belt analyzer of its kind in the world today. AllScan\u00ae has two key advantages over other analyzers:<\/p>\n
- \n
- A much higher tolerance to changing coal types (e.g. from different seams), eliminating the need for multiple calibrations<\/li>\n
- It provides much more information than just ash, as it directly measures individual elements like Fe, Al, Si, K, S, Ti, Ca and other elements. The AllScan\u00ae has proved results for measurement of trace elements such as P, Hg, As and Se. The AllScan\u00ae also directly measures moisture.<\/li>\n<\/ul>\n
Combining state-of-the-art nuclear technology (PGNAA) with ground spectral modelling (sophisticated algorithm DURA-G\u2122 incorporated to reduce dramatically measurement error), the AllScan\u00ae delivers accurate, minute by minute elemental analysis and reporting of key process parameters.<\/p>\n
