Successful sample preparation for most analytical techniques (HPLC, GC, spectrophotometry, RIA, etc.) has a threefold objective: namely, to provide the sample component of interest. in solution free from interfering matrix elements at a concentration appropriate for detection or measurement.
An innovative solid phase extraction (SPE) sorbent that offers a faster, cleaner way to extract your samples, completely revolutionizing traditional SPE methods. Traditional SPE
Solid Phase Extraction is a sample preparation technique that uses solid chromatographic material packed in a plastic cartridge to separate different dissolved compounds contained in a liquid sample.
17 lis 2015 · Overview. • Basic Theory. – Why do we need sample preparation? – Different SPE workflows. – Retention Mechanisms. • Method Development. – Example: extracting amitriptyline from serum. – Sorbent...
Solid phase extraction (SPE) is an increasingly useful sample preparation technique. With SPE, many of the problems associated with liquid/ liquid extraction can be prevented, such as incomplete phase separations, less-than-quantitative recoveries, use of expensive, breakable
Summary. Questions and Wrap Up. UPDATING EXISTING SPE METHODS-WHY? The Need for Updating Existing SPE Methods. Requirements for lower detection limits. Improved linearity in the lower or upper concentration range and calibration range extension. Limited sample volume.
Solid phase extraction (SPE) is a broad term used to describe the separation technique in which liquids contact modified solid surfaces and a component of the liquid adheres to the solid. In a separate step, the solid releases the component.
