What is the SPME?
Ela combina com sucesso a amostragem, o isolamento e o enriquecimento do analito em uma única etapa. A SPME é amplamente utilizada para amostragem de voláteis ambientais e amostras de bebidas e alimentos, flavorizantes e aromatizantes, análises forenses e de toxicologia e farmacêuticas.
What is a special purpose entity (SPE)?
Usually, a sponsoring corporation hives off assets or activities from the rest of the company into an SPE. This isolation of assets is important for providing comfort to investors.
What does SPME stand for?
Solid-phase microextraction, or SPME, is a solid phase extraction sampling technique that involves the use of a fiber coated with an extracting phase, that can be a liquid ( polymer) or a solid ( sorbent ), which extracts different kinds of analytes (including both volatile and non-volatile)...
What is SPME sampling and how does it work?
The most widely used form of SPME sampling consists of exposing a thin polymeric coating directly to the sample matrix for a predetermined amount of time as shown in figure below. Once the fibre is exposed to the sample matrix, the transport of analytes from the matrix to the coating begins immediately.
What are the best products for SPME sample preparation?
Agilent offers high-quality products for SPME sample preparation An Agilent Guide to SPME Analysis; DE.222337963 Solid Phase Microextraction (SPME) is a fast, solvent-less sample extraction technique. It is used for extracting organics from a matrix (solid, liquid, or gaseous) into or onto a stationary phase immobilized on a fiber.
What are analytes in SPME?
In SPME, analytes establish equilibria among the sample matrix, the headspace above the sample, and a polymer-coated fused fiber. Two types of extraction:
