Solid Phase Micro Extraction (SPME)
Solid Phase Micro Extraction (SPME)
Solid phase micro extraction (SPME) sample preparation reduces sample handling and solvent consumption, and it has many applications in environmental, food, clinical, and other industries. SPME fibers are used to extract organic compounds from solid, liquid, and vapor matrices onto a stationary phase that is bonded to a fused silica fiber. Typically, the analytes are then thermally desorbed in the inlet of a gas chromatograph (GC).
Restek PAL SPME Fibers
• Suitable for a wide range of polar and nonpolar target analyte chemistries and sample matrices.
• Reliable performance meets or exceeds other brands.
• Robust aluminum hub is more durable than plastic.
• Optimized for PAL system autosamplers and compatible with most GC inlets.
• SPME automated sample preparation reduces sample handling and solvent consumption.
The Restek PAL SPME Fiber products include the following:
• 7 μm PDMS fibers are recommended for nonpolar, high molecular weight analytes (125–600 Da).
• 30 μm PDMS fibers are recommended for nonpolar, semivolatile analytes (80–500 Da).
• 100 μm PDMS fibers are recommended for volatile analytes (60–275 Da).
• 85 μm Polyacrylate fibers are recommended for polar, semivolatile analytes (80–300 Da).
• 95 μm Carbon Wide Range (WR)/PDMS fibers are recommended for gases and highly volatile low molecular weight analytes (30–225).
*All Restek PAL SPME fibers are 10 mm in length and are housed in a 23-gauge needle. The phase is bonded onto a fused silica fiber core.
