Description

Description générale

Pour les gaz et les composés de faible poids moléculaire (MW 30-225)

Solid phase microextraction (SPME) technique is generally used for GC/MS analysis. It helps in simplifying and speeding up the sample preparation. It also reduces solvent requirement during extraction.

We are committed to bringing you greener alternative products, which adhere to one or more of The 12 Principles of Greener Chemistry. This is a Solid Phase Microextraction (SPME) technology product. SPME is one of the greener technologies for sample preparation as it is solvent free extraction technology and SPME fibres are re-usable and generates as little waste as possible, thus aligns with "Waste Prevention”, and ″Safer Solvents and Auxiliaries″.

Application

SPME fiber assembly (CAR/PDMS) was used:

• to extract volatiles from headspace vial of cheese samples.
• to measure dimethyl sulphide concentrations of Ulva lactuca.
• in determination of 2-Heptanone concentrations.

Note de bas de page

This SPME fiber assembly is also available with a Nitinol (NIT) core as Cat. No. 57908-U, providing enhanced fiber reproducibility, greater fiber durability, maintained selectivity for method consistency, and core inertness to ensure analyte stability. See more at SigmaAldrich.com/NITSPME .
