- Suitable for a wide range of 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
Solid phase microextraction (SPME) is an automated sample preparation technique that reduces sample handling and solvent consumption. SPME technology has many applications in environmental, food, clinical, and other industries. Restek PAL SPME fibers are high-performing fibers that meet or exceed the performance of other brands. Our reliable SPME fibers are optimized for PAL system autosamplers and are compatible with most GC inlets. Restek SPME fibers are suitable for a wide range of analyte chemistries and sample matrices.
Our SPME product line is continually expanding and our current products and recommended uses 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.
