 QMBalance | Dr. SchömerWorld Premiere: standard addition method with Uncertainty - ProControl ® 6.1 in Excel | |
The Aufstockverfahren (standard addition, spiking, DIN 32,633) is used, the accuracy of analytical results also provide even when changing sample matrices to calibrate an appreciable influence. Analysis and determining the analytical results is made by extrapolating the with addition of the unknown sample obtained calibration on the x-axis. World Premiere - Uncertainty realistically:As the world's first commercially available and validated software determines ProControl ® 6.1, the analysis results directly with uncertainty, taking into account the first supplementary, practically relevant uncertainty contribution of the extrapolation. Decision in the limit - is the cost of standard addition necessary?From the Aufstockversuch realistically uncertainty provides the first an important additional decision criterion: the considerable expense of Aufstockverfahrens in routine respond instead, can systematic errors as a tolerable show, and uncertainty contribution to the analysis results will be integrated further than, in order to ensure its accuracy. Decision criterion: "uncertainty" actually improved?When random and cause additional systematic errors of calibration in the solvent without sample matrix, a smaller uncertainty than the uncertainty that results in Aufstockverfahren, is open to the above described way. The Aufstockverfahren enhanced in this case, the accuracy is only apparent. Of course, this option is ruled out if the uncertainty of actually smaller Aufstockverfahrens fails. The substantial additional effort is justified but then shown. ProControl ® 6.1 allows you first to report, even in this case - without any additional measurement to - your analysis results directly with the appropriate, realistic-assessed outcome uncertainty. Numerous other reports on statistical methods are available. ProControl ® has been established in 1996 as a software validation and validated itself as a software. QMBalance | Dr. Schömer ensures compatibility of ProControl ® 6.1 for Excel versions 12.0 to 8.0 for almost all current operating systems and network environment. The new version 6.1 with ProControl ® supports add-on control charts and trend forecast of one-sided specification identification, control and evaluation of release profiles.  |
