Single-walled carbon nanohorns are made of graphene sheets with long cone-shaped tips with the diameters of 2-5 nm and the length of 40-50 nm. Thousands of carbon nanohorns form spherical aggregates of about 100 nm in diameter.
Fast and Simple Cleanup for Mycotoxin Analysis.The need for a quick, simplistic sample cleanup approach prior to chromatographic mycotoxin analysis has brought about SPE cartridges that significantly decrease sample prep time, increase reproducibility, and are more user friendly as compared to the industry standard immunoaffinity columns. In addition the Supel Tox SPE approach requires less equipment and fewer consumables.Unli…
A new generation of SPME products.The Fast Fit Fiber Assemblies were developed by Chromline srl Prato Italy in cooperation with Supelco expanding the applicability of SPME for rapid sampling and analysis using multiple fiber assemblies. This product line is centered around the barcoded SPME Fast Fit Assemblies that can be automatically exchanged on a CTC CombiPAL type autosampler equipped with the Multi Fiber EXchanger (MFX) s…

BIOshell™ A160 Peptide C18, 2.7 μm HPLC Columns BIOshell A160 Peptide C18 columns packed with 2.7 μm particles, 160 Å pores, are as efficient as sub-2-μm porous particles, but at ½ the backpressure.These columns can be operated long term at pressures up to 600 bar (60 MPa or 8500 psi), temperatures up to 90 °C and within the pH range of 1 to 8. BIOshell A160 Peptide C18 columns can be run on all HPLC systems including UHPLC s…
Radiello™ Cartridge Adsorbents for sampling HF, NO2, and SO2, matrix microporous PE impregnated with wet TEA.Passive or diffusive sampling relies on the diffusion of analytes through a diffusive surface onto an adsorbent. After sampling, the analytes are chemically desorbed by solvent extraction or thermally desorbed and analyzed. Passive sampling is quiet, non-flammable and does not represent an explosion hazard. It can be pe…
Radiello™ Cartridge Adsorbents for sampling Ammonia (NH3), matrix microporous PE impregnated with phosphoric acid.Passive or diffusive sampling relies on the diffusion of analytes through a diffusive surface onto an adsorbent. After sampling, the analytes are chemically desorbed by solvent extraction or thermally desorbed and analyzed. Passive sampling is quiet, non-flammable and does not represent an explosion hazard. It can…
Radiello™ Cartridge Adsorbents for sampling BTEX and VOCs (CS2 Desorption), matrix SS net (100 mesh, 5.8 mm diam.), activated with activated charcoal (30-50 mesh).Passive or diffusive sampling relies on the diffusion of analytes through a diffusive surface onto an adsorbent. After sampling, the analytes are chemically desorbed by solvent extraction or thermally desorbed and analyzed. Passive sampling is quiet, non-flammable an…
“QuEChERS” (Quick, Easy, Cheap, Effective, Rugged, and Safe) - Supel™ QuE PSA Tube, pk of 50, suitable for EN 15662:2008 per BSDispersive SPE (dSPE), often referred to as the "QuEChERS" method, is an emerging sample prep technique that is becoming increasingly popular in the area of multi-residue pesticide analysis in food and agricultural products. In dSPE, food/agricultural samples are first extracted with aqueous miscible…
