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 μm particles while maintaining lower backpressures. The combination of high efficiency and low backpressure benefits UPLC® (or other ultra high pressure system) users, as well as conventional HPLC users. Column Details: Mode of chromatography: Hydrophilic interaction…
Application: The 35% phenyl equivalent phase provides a higher polarity option compared to columns containing a lower phenyl content, resulting in a greater retention of polar analytes relative to non-polar compounds. Its selectivity is complementary when paired with SLB-5ms for applications that require dual-column confirmatory analysis, such as for environmental analytes (such as pesticides, PCBs, and herbicides). The low…
The SupelMIP SPE line consist s of highly cross-linked polymers that are engineered to extract a single analyte of interest or a class of structurally related analytes with an extremely high degree of selectivity. This is possible because selectivity is introduced during MIP synthesis in which a template molecule, designed to mimic the analyte, guides the formation of specific cavities or imprints that are sterically and chemi…
Dispersive SPE (dSPE), often referred to as the "QuEChERS" method (Quick, Easy, Cheap, Effective, Rugged, and Safe), is modern sample prep technique that is becoming increasingly popular in the area of multi-residue pesticide analysis in food and agricultural products. Using the QuEChERS method, food/agricultural samples are first extracted with an aqueous miscible solvent (e.g., acetonitrile) in the presence of high amoun…
Introducing the Supel-Select SCX SPE Tube from Sigma Aldrich
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…
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…
