| technique(s) | solid phase microextraction (SPME): suitable |
| Features and Benefits: | Designed for use with Merlin Microseal sealing system; can be used with other septumless systems. |
| Footnote: | Coating bonded to a flexible fused silica core, yielding a more suitable coating on a less breakable fiber. There may be a slight difference in extraction selectivity compared to the same coating on a standard fused silica core. 2cm fiber assembly contains no spring. |
| General description: | SPME fiber assemblies can be reused for up to 100 analyzes, or more, depending on the application and the care they are given. For reuse, simply condition with heat before and after every analysis. Solvent can be used for HPLC applications or when heat does not sufficiently clean the fiber. Each assembly has a color-coded or notched hub indicating the type of coating on the fiber. Smaller molecules are retained in the pores of the fibers containing adsorbents in the coating; e.g. carboxen, divinylbenzene particles. |
| General description: | 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″.
