The ADPOL module comprises of:
The ADPOL module comprises of:
This system is a full-vacuum instrument, the vacuum level is microprocessor-controlled and the duty cycle of the
vacuum pump is typically less than 5%. The spectrometer software is a Windows 7 based program for spectrometer control and measured data processing.
We offer sophisticated near-infrared instrumentation solutions and applications for materials measurement & research.
The QSN 750-II and QSG 750-II spectrometers can be equipped with an automatic spark stand cleaning device. The device automatically removes debris from the counter-electrode and also cleans the spark stand table. In between the measurements, the device closes the sparking stand hole, avoiding dust to enter the spark stand.
For process control of a cement plant the elemental composition of raw materials, raw meal, clinker and cement needs to be measured accurately on a continuous basis. The results have a direct impact on production process parameters such as feed speeds, kiln temperatures, grinding times etc. Optimizing these helps to minimize production costs. Moreover, accurate analyses also assure product quality and consistency. X-ray fluorescence (XRF) spectroscopy has become an established analytical method for quantifying the elemental composition of cement and related materials. XRF delivers important advantages, straightforward sample preparation, accurate and reproducible results and highly automated analysis. XRF reduces measurement times to a matter of minutes and allow routine analysis to be carried out by factory operators. Plants often rely on pressed pellets for routine analysis, since the preparation of fused beads, which give more accurate and reliable results, is more elaborate and costly. To avoid mineralogical effects, which can lead to analysis errors, standards and unknowns need to have the same mineralogy and origin. Samples from primary materials and the production process that cover the widest possible concentration ranges need to be supplied by the customer. These are then prepared as fused beads and analyzed using PANalytical’s cement application that includes the very accurate CEMOXI standards set. Pressed pellet applications are then set up using the data generated.
Statistical Process Control (SPC) is proven to be a valuable tool in many laboratories to monitor processes and performances of various analytical instruments.
With SPC in many cases a change in the process, or in the instrument performance, is noted before the measurement is out of control, i.e. when the results are still within the acceptance limits. Timely actions can be taken, to prevent the next batch of material being discarded, thus saving costs. Apart from quality control, SPC can also be used to provide a continuous record of system performance for ISO-type laboratory accreditation.
The low alloy steel (LAS) calibration package can be calibrated on 2.4, 3 or 4 kW, and is retrofittable. The low alloy steel (LAS) package comprises of:
The low alloy steel (LAS) calibration has been setup using more than 90 certified reference materials sourced from several suppliers. To pre-calibrate Zetium and Axios FAST spectrometers, this master calibration is transferred using six CRMs using the SuperQ Calibration update.
The low alloy steel (LAS) pre-calibration package is ideal for the analysis of:
Turn-key solutions for accurate and precise elemental analysis of low alloy steel compositions to optimize process and quality control of the steel industry.
