The Ascentis Express biphenyl phase chemistry offers alternative selectivity for pharmaceutical analytes and drug metabolites that are not well retained or difficult to resolve on traditional alkyl (C18) and phenyl bonded phases. Ascentis Express HPLC columns, through the use of Fused-Core® particle technology, can provide you with both the high speed and high efficiencies of sub-2 ?m particles while maintaining lower backp…

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…

The polar organic and the polar ionic modes have become increasingly popular largely because of their ideal compatibility with MS detection and preparative LC. Two years of extensive research at Astec in understanding these mechanisms has resulted in new possibilities for extending their effectiveness even further. Important changes in linkage chemistries and the silica and the silica have now led to the new CHIROBIOTIC V2 and…

bed wt. 25 mg, volume 10 mL , (LRC), pk of 50 Application A class selective MIP phase for the multi-residue extraction of beta-agonists in urine, tissues, and other biological fluids. SupelMIP - Beta-agonists was developed for the selective extaction of a broad range o beta-agonists such as brombuterol, clenbuterol, formoterol, isoxuprine, mapenterol, ractopamine, ritrodine, salbutamol, salmeterol, terbutaline, tulobuterol, zi…

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…
