Sample pretreatment on microfabricated devices
Talanta, 2002The integration of sample pretreatment into microfluidic devices represents one of the remaining hurdles towards achieving true miniaturized total analysis systems (muTAS). The challenge is made more complex by the enormous variation in samples to be analyzed.

Further restrictions arise from the fact that good isocratic separations can only be obtained wi th in a limited k' range. In addition, accurate quantif ication of traces and main compounds in one run is limited to trace concentrations of at least 100ppm.

Hydrophilic materials in sample pretreatment
TrAC Trends in Analytical Chemistry, 2017Abstract Sample pretreatment is a fundamental and essential step in almost all analytical procedures, especially for the analysis of biological and environmental samples with complex matrix. In the past decades, with the development of hydrophilic interaction liquid chromatography (HILIC) in the separation of polar compounds, hydrophilic materials ...

SAMPLING AND SAMPLE PRETREATMENT FOR ENVIRONMENTAL ANALYSIS
2006The sample pretreatment methods are constantly developing aiming to respond to the large variety of samples source and composition. For example, in order to preconcentrate toxic metals from liquid samples the most used methods are the extraction, based on extraction agents like chelates and ion-pairing are, used after the samples' digestion.

Pretreatment of biological sample for microchip analysis
2006A number of analytical processes have been developed on microchips for genomic and proteomic analysis, but reaching the analytical step often requires significant preprocessing before the sample reaches the microchip. Development of microchips that perform these sample processing steps is now underway to take advantage of the speed and cost benefits ...

Critical evaluation of sample pretreatment techniques
Analytical and Bioanalytical Chemistry, 2009Sample preparation before chromatographic separation is the most time-consuming and error-prone part of the analytical procedure. Therefore, selecting and optimizing an appropriate sample preparation scheme is a key factor in the final success of the analysis, and the judicious choice of an appropriate procedure greatly influences the reliability and ...

Correlation of Environmental Sample Radioactivity Determination With Sample Pretreatment
Health Physics, 1980Abstract This report describes a calculation equation for radioactivity determination, and sample pretreatment based on the fundamental design mentioned in previous report (Na79), which satisfied the guide for dose assessment objectives for a light-water-cooled nuclear power reactor (AECJ75).

A microbead-incorporated centrifugal sample pretreatment microdevice
Lab on a Chip, 2013In this study, we present a novel bead-incorporated centrifugal sample pretreatment microdevice to purify influenza A H3N2 viral RNA. Simple revolution per minute (RPM) control can lead to RNA capture on a bead-bed, and the sequential loading of a washing solution and an elution solution.
