詳細
Ascentis Express 5 μm RP-Amideは、効率性の高いFused-Core®粒子設計を有する、高速のHPLCカラムです。Fused-Core粒子は、固形のシリカコアを薄い多孔性の高純度シリカのシェルで覆っています。この粒子設計は、0.6 μm厚の多孔性シェルと高均一で全体の粒子径5 μm内の浅い拡散経路により、極めて高いカラム効率を示します。Ascentis Express 5 μm RP-アミドのone-step bonded、エンドキャップ型、アミドベース、極性埋込型固定相により、疎水性の低下した安定化逆相充填剤が得られます。Ascentis Express RP-アミドは、C18またはC8によるオルソゴナルな選択性を有する塩基性、酸性、または中性化合物に使用可能です。極性埋込型Ascentis Express 5 μm RP-アミドカラムは、「崩壊」を起こすことなく100％水性移動相と適合します。

A liquid chromatography-linear ion-trap spectrometry (LC-MS³) method using β-receptor molecular-imprinted polymer (MIP) solid-phase extraction (SPE) as clean-up was developed to determine simultaneously and confirmatively residues of 25 β₂-agonists and 21 β-blockers in urine samples. Urine samples were subjected to enzymatic
