Title
(JA) GC×GCを用いた炭化水素サンプル中の汚染の高精度評価
Abstract
(JA)

本発明は、油ベース泥水の濾過水による炭化水素サンプルの汚染を見積もる方法に関する。この方法は、油ベース泥水の濾過水により汚染された炭化水素サンプルを得るステップと、次いで汚染された炭化水素サンプルを、二次元ガスクロマトグラフィー(CG×CG)を用いて分析するステップとを含む。この方法は、さらに、汚染された炭化水素サンプル中の油ベース泥水の1つ以上の固有の成分又はトレーサーを同定するステップを含む。最後に、この方法は、1つ以上の固有の成分又はトレーサーのピーク体積を加算し、そして汚染されていない炭化水素サンプルのピーク体積に対して比をとるステップを含む。
