DEVICE AND METHOD FOR MAGNETIC IN-TUBE SOLID-PHASE MICROEXTRACTION
WO13011171
In-tube solid phase microextraction (IT-SPME) is a well known sample preparation technique for its coupling with analytical instruments, like capillary liquid chromatography. In this technique, extraction, desorption and injection can be performed automatically, shortening the analysis time and improving precision. Researchers from Universitat de València have designed a new IT-SPME on the basis of magnetic microfluidic principles improving extraction efficiency of conventional IT-SPME systems. The new system called Magnetic-IT-SPME allows quantitative extraction efficiency using magnetic hybrid materials as adsorbent phase into capillary columns and applying external magnetic fields.
Applications: This analytical instrument is useful for all those sectors that require high sensitivity of analyte quantification, particularly for organic compounds. For example: - Environmental industry - Pharmaceutical industry - Food industry - Biochemistry - Medical chemistry - Industrial chemistry Advantages: The device has the following advantages over existing equipment: - Allows quantitative extraction efficiency, solving one of the main drawbacks of IT-SPME systems - Broadens applicability of IT-SPME thus making available its advantages (automation, precision) to specific analyses that require high sensitivity of analyt
