Internal standard addition (ISA) is a new calibration method that combines the principles of internal standardization and standard additions. The current work demonstrated the effectiveness of ISA for the determination of ...

The standard additions (SA) method is one of the most important calibration strategies in quantitative chemical analysis. It is a powerful tool to minimize matrix effects and enable precise and accurate determinations. On ...

The cumulative standard addition method allows the calibration of an instrument affected by matrix effects when a small sample volume is available. Recently, it was developed and validated a metrologically sound procedure ...

The conventional curriculum of Analytical Chemistry undergraduate courses emphasizes the introduction of techniques, methods and procedures used for instrumental analysis. All these concepts must be integrated into a sound ...

In the presence of analyte-background interactions and a significant background signal, both second-order multivariate calibration and standard addition are required for successful analyte quantitation achieving the ...

Pilot sintering tests were performed in order to compare production parameters and quality of sinters produced based on Western Europe and Asia standard mixtures, with sinters produced from the addition of Samarcos pellet ...

Judicial ideology in court has attracted the attention of political scientists and legal economists. The question we address here is the extent to which ideological stability impacts the law. We consider a model where a ...

A new strategy for the determination of riboflavin (RF, or vitamin B2) in human urine samples has been developed, combining excitation-emission fluorescence matrix (EEFM) data in standard addition mode and second-order ...

An analytical procedure for multiple standard additions of arsenic species using sequential injection analysis (SIA) is proposed for their quantification in seafood extracts. SIA presented flexibility for generating multiple ...
