What is SPME in GC?
The solid-phase microextraction followed by gas chromatography-mass spectrometry method (SPME-GC-MS) was widely used to identify and quantify the volatile compounds in liquid food, such as wine (Heaven and Nash 2012).
What is microextraction method?
Microextraction is defined as an extraction technique where the volume of the extracting phase is very small in relation to the volume of the sample, and extraction of analytes is not exhaustive. From: Journal of Chromatography A, 2000.
What is purge and trap method?
Purge and trap refers to the headspace technique in which volatile organic compounds (VOCs) are purged out of the sample matrix by an inert gas and carried onto a sorbent trap, where they are concentrated and later introduced into an instrument (e.g., gas chromatography (GC) or GC/mass spectrometry (MS)) for analysis.
Is SPME a destructive analysis?
The SPME sampling methods developed in this study are non-destructive and suitable for semi-quantitative determination of PCP in original wooden museum objects.
What is SPME arrow?
The SPME Arrow is a new technology for micro-extraction, combining trace level sensitivity with high mechanical robustness. The SPME Arrow has a large sorption phase surface resulting in two times higher sample throughput. The arrow-shaped tip allows smooth penetration of vial and injector septa.
What is direct immersion?
The extraction of samples can be performed using two methods. The second method is direct immersion (DI-SPME), in which the fiber is directly immersed in a small volume of the liquid-extracted sample [5,6,7].
Is gas chromatography qualitative or quantitative?
Gas chromatography (GC) can be used for both qualitative and quantitative analyses. This chapter begins with a brief look at qualitative analysis. The chromatographic parameter used for qualitative analysis is the retention time or some closely related parameter.
What is SPME analysis?
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 is SPME coating?
The SPME fibre itself is a thin fused-silica optical fibre, coated with a thin polymer film (such as polydimethylsiloxane (PDMS)), conventionally used as a coating material in chromatography. There are two typical SPME applications, sampling gases (headspace (HS)) or sampling solutions.
