Polydimethylsiloxane/Divinylbenzene (PDMS/DVB) SPME Fibers.Solid Phase Microextraction (SPME) is an innovative, solvent-free sample prep technology that is fast, economical, and versatile. SPME uses a fiber coated with a liquid (polymer), a solid (sorbent), or a combination of both. The fiber coating removes the compounds from your sample by absorption in the case of liquid coatings or adsorbtion in the case of solid coatings.…

The Next Generation in Hybridspe-Phospholipid Technology

Tedlar® gas sampling bags are recommended in many US EPA methods including TCLP and methods TO-3 (VOCs), TO-12 (NMOC), TO-14A (VOCs), TO-15 (VOCs), ASTM D-5504 (reduced sulfur compounds) and a variety of atmospheric gas methods. Tedlar® bags are an excellent value and offer several features over competitor versions.   Benefits: Unique valve and seam-sealing process ensure bags are sturdy and leak-proof under the mo…

Patent pending HybridSPE – Precipitation (HybridSPE-PPT) technology is a simple and generic sample prep platform designed for the gross level removal of endogenous protein and phospholipid interferences from biological plasma and serum prior to LC-MS or LC-MS/MS analysis. Biological plasma or serum is first subjected to protein precipitation via the addition and mixing of acidified acetonitrile. Precipitated proteins are then…
