詳細
SPB®-Octyl Capillary GC Column has high resolution and it provides reliable congener separations.
用途:このカラムの極性はスクアランに匹敵するほど低いため、広く使用されている非極性ポリ(ジメチルシロキサン)カラムより著しく低い極性を示します。このカラムは非極性カラムや中極性カラムにない独特な選択性を持つため、PCBを含有する試料の確認分析に使用できます。

アプリケーション
SPB®-Octyl Capillary GC Column was used in solid-phase microextraction-capillary gas chromatography combined with microwave-induced plasma atomic-emission spectrometry (GC-MIP-AED), for speciation of selenite (SE(IV)) as it is an element which is essential at low levels and is considered at higher levels.
