A Two-Component Model for Measurement Error in Analytical Chemistry

In this article, we propose and test a new model for measurement error in analytical chemistry. Often, the standard deviation of analytical errors is assumed to increase proportionally to the concentration of the analyte, a model that cannot be used for very low concentrations. For near-zero amounts, the standard deviation is often assumed constant, which does not apply to larger quantities. Ne...

Detection limits and goodness-of-fit measures for the two-component model of chemical analytical error

The utility of analytical chemistry measurements in most applications is dependent on an assessment of measurement error. This paper demonstrates the use of a two-component error model in setting limits of detection and related concepts and introduces two goodness-of-fit statistics for assessing the appropriateness of the model for the data at hand. The model is applicable to analytical methods...

A nonlinear component of the analytical error

Background In clinical chemistry, a number of studies shows that the probability of very large errors is much greater than expected from the Gaussian distribution. In addition, it has been empirically found that the behavior of nonlin-ear complex systems is often asymptotically exponential. Consequently, we may assume that the error of some analytical systems may be approximated by the sum of a...

Quantifying Measurement Uncertainty in Analytical Chemistry – a Simplified Practical Approach

Following a simple and practical approach can minimize the headaches of calculating the components of measurement uncertainty. Basic requirements for planning an analysis, realistically estimating the magnitude of uncertainty sources, and combining uncertainty components will be presented using examples of analytical chemistry methods.

Analytical Solution for Two-Dimensional Coupled Thermoelastodynamics in a Cylinder

An infinitely long hollow cylinder containing isotropic linear elastic material is considered under the effect of arbitrary boundary stress and thermal condition. The two-dimensional coupled thermoelastodynamic PDEs are specified based on equations of motion and energy equation, which are uncoupled using Nowacki potential functions. The Laplace integral transform and Bessel-Fourier series are u...
