Rtx-5MS的固定相也是交聯、鍵合的5%二苯基-95%二甲基聚硅氧烷，熱穩定性可達360℃。但是其合成與鍵合工藝比標準含5%苯基的聚合物有更一步的改進。使其流失性更低，能滿足質譜分析的特殊要求。在分析堿性到中性與酸能抽取物，并使用高靈敏度的檢測器，如ITD、MS、GCD或者甚至FID時，色譜柱的流失會帶來某些問題。它會導致不準確的分析結果，誤導質譜圖解析、降低靈敏度，在極端的情況下，還會得到錯誤的定性結果。每支Rtx-5MS柱都經過嚴格的測試，保證它們能得到一致的結果。每批Rtx-5MS所使用的聚合物都經質譜測試，并必須附合對低流失和最低硅氧烷碎片的要求規格。而且用許多最有吸附性的指標化合物配成的嚴格測試混合物，對Rtx-5MS柱進行性能評估。建立了最低響應因子的指標，以保證每支柱都能超過半揮發污染物測試方法中的要求。每支柱的流失情況，確保在最大使用溫度時的超低流失的水平。提供的每支柱都附有實際測試的色譜圖，可說明Rtx-5MS對環境化合物所顯示出的高度惰性。同時也附有能說明質譜檢測器對聚合物流失反應的測試色譜圖。Rtx-5MS所顯示的性能超過了測試半揮發污染物的EPA方法625和8270的要求。該柱相似于Quadrex007-5MS,DB-5MS和HP-5MS。 規格 規格DB-5MS,25m,0.20mm,0.33umHP-5MS,12m,0.20mm,0.33umDB-5MS,50m,0.20mm,0.33umHP-5MS,25m,0.20mm,0.33umDB-5MS,12m,0.20mm,0.33umHP-5MS,50m,0.20mm,0.33umDB-5MS,15m,0.25mm,0.25umHP-5MS,15m,0.25mm,0.10umDB-5MS,15m,0.25mm,1.00umHP-5MS,15m,0.25mm,0.25umDB-5MS,15m,0.25mm,0.50umHP-5MS,15m,0.25mm,1.00umDB-5MS,25m,0.25mm,0.25umHP-5MS,30m,0.25mm,0.10umDB-5ms,25m,0.25mm,0.40umHP-5MS,30m,0.25mm,0.25umDB-5MS,30m,0.25mm,0.10umHP-5MS,30m,0.25mm,0.50umDB-5MS,30m,0.25mm,0.25umHP-5MS,30m,0.25mm,1.00umDB-5MS,30m,0.25mm,1.00umHP-5MS,60m,0.25mm,0.10umDB-5MS,30m,0.25mm,0.50umHP-5MS,60m,0.25mm,0.25umDB-5MS,50m,0.25mm,0.25umHP-5MS,15m,0.32mm,0.10umDB-5MS,60m,0.25mm,0.10umHP-5MS,15m,0.32mm,0.25umDB-5MS,60m,0.25mm,0.25umHP-5MS,15m,0.32mm,1.00umDB-5MS,60m,0.25mm,1.00umHP-5MS,25m,0.32mm,0.52umDB-5MS,15m,0.32mm,0.10umHP-5MS,30m,0.32mm,0.10umDB-5MS,15m,0.32mm,0.25umHP-5MS,30m,0.32mm,0.25umDB-5MS,15m,0.32mm,0.25umHP-5MS,30m,0.32mm,0.50umDB-5MS,15m,0.32mm,1.00umHP-5MS,30m,0.32mm,1.00umDB-5MS,25m,0.32mm,0.52umHP-5MS,60m,0.32mm,0.10umDB-5MS,30m,0.32mm,0.10umHP-5MS,60m,0.32mm,0.25um
