FeaturesFeatures13.High Sensitivity and High PrecisionThe adoption of the new X-ray tube of the end-window type and the short distance between the X-ray output port ofthe X-ray tube and the sample provides high intensity of the fluorescent X-rays; this enhances the sensitivity for traceelements and improves the detection limits.The use of curved crystals and curved dispersion elements enhances the resolution, while the adoption of a gassealed proportional counter, an automatic core wire winding type detector, temperature control unit for thespectrometer, and the high-performance counting circuit provides high precision.The degree of vacuum is controlled and stabilized by the CPU, which also enhances the stability of light-elementanalysis.Typical Detection Limits and RepeatabilityLow-alloy steelIntegration time: 40 sec.SiMnPSNiCrCuMoDetection limit0.00130.00060.000450.00040.00080.00020.00060.00045RepeatabilityConcentrationStandard deviationCoefficient of variation0.2230.00110.50.660.00080.130.0150.00021.30.0170.000221.31.990.00160.080.690.00070.10.0420.00030.70.190.000250.13Cast ironIntegration time: 40 sec.CSiMnPSMgRepeatabilityConcentrationStandard deviationCoefficient of variation3.570.0170.491.70.170.10.5030.00040.080.0470.000250.550.0420.00020.470.0410.00082Copper alloyIntegration time: 40 sec.CuZnMnSiAlSnPbFeRepeatabilityConcentrationStandard deviationCoefficient of variation57.00.010.01838.00.010.0260.260.000350.130.0140.000684.80.060.000420.70.170.00070.40.0110.0003330.0190.000271.4Ceramic cementIntegration time: 40 sec.SiO2Al2O3Fe2O3CaOMgOSO3Na2OK2ORepeatabilityConcentrationStandard deviationCoefficient of variation14.00.00630.0453.00.00240.082.00.00080.0443.00.0060.0140.80.0040.52.00.00140.071.00.0060.60.40.00050.1312
