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.
The information about novel methodological and instrumental solutions in relation to different variants of SPE techniques, solid-phase microextraction (SPME), in-tube solid-phase microextraction (IT-SPME), and magnetic solid-phase extraction (MSPE) is presented.
Solid-phase extraction (SPE) technique was developed as an al-ternative practice in 1970s to liquid-liquid extraction (Thurman and Mills, 1998). Now, SPE is one of the widely used sample preparation methods for trapping analytes and separating them from sample matrix. Solid-Phase Extraction procedure, disposable car-
24 wrz 1999 · The objective of this review is to provide updated information about the most important features of the new solid-phase extraction (SPE) materials, their interaction mode and their potential for modern SPE. First, the recent developments are given in formats, phases, automation, high throughput purpose and set-up of new types of procedures.
1 sty 2006 · Solid phase extraction (SPE) is an extraction method that uses a solid phase and a liquid phase to isolate one, or one type, of analyte from a solution. It is usually used to clean up a...
This book is designed to help you explore and understand a very powerful tool in sample preparation technology: solid-phase extraction [SPE]. You will see how this technology, which uses devices with chromatographic packing material, can help meet your analytical challenges.
SPE Separation Mechanisms. Recognizing the primary mechanisms of interaction present in most SPE products can help you determine what is important to know about your sample. There are two principal mechanisms for interaction used in most SPE products: polarity and ion exchange.
