VF系列GC-MS毛细管柱(FactorFour系列)综述

提高灵敏度
色谱柱的柱流失越低，检测灵敏度就越高。这不仅仅是对于质谱(MS)的使用者，对于拥有ECD、NPD、TSD、
FID、PDD、AED以及PID等检测器的实验室来说，越高的灵敏度，就意味着越低的检测限，以及痕量和超痕量分析的可能。一般来说，FactorFour和其他“低流失柱”相比，灵敏度高出两倍以上。

对GC/MS用户而言，使用低流失色谱柱是分析工作的保证。图2中我们可以看到，从普通质谱柱中流出的痕量物质难以被分析和确认；而采用 FactorFour色谱柱，由于有非常低的柱流失率，大大降低了噪声指标，得到了更低的检测下限。我们可以轻松的对流出的痕量化合物进行准确定性定量分析。没有一款色谱柱有FactorFour这样好的准确性，灵敏度和再现性。FactorFour，是您实验室的最佳选择!

稳定快速
FactorFour超低流失毛细管柱可以快速地进行老化处理，快速地达到稳定。这对于一个实验室来说，真正地提高了工作效率。不仅是用到了最好的色谱柱，而且在固定的时间里可以完成比往常更多的分析工作。(图5)

改善谱图的完整性
当一位GC/MS实验人员得到分析谱图后，都会在标准谱库中进行检索，以期拿到正确的分析结果。而这种检索往往都是按照一定的规则自动进行的。如果我们使用有较高流失的色谱柱，柱流失物产生的干扰就会明显地增加，对于我们做痕量化合物分析鉴定工作(GC/MS)会产生很大的阻碍。如果您使用 FactorFour色谱柱，我们就能够把这样的干扰降到最低限。也就是说，通常色谱柱所产生的极少的流失物，如聚二甲基硅氧烷等-通常在m/z 73、207和281，不会影响到最终谱图在谱库中的检索过程，从而可以得到所要检测化合物的正确信息。所以说，柱流失越低，所产生的干扰离子对分析结果的影响就越低，分析结果就会更加真实可靠。(图3)

更长的色谱柱寿命
色谱柱使用到一定程度后，就不会有正常的表现了。这是因为色谱柱内键合相(固定相)的脱落。
FactorFour采用特殊的键合技术，使得色谱柱的流失程度降至最低，延长了色谱柱的使用寿命，减少了分析实验工作的成本。(图4)

                VF-35MS  VF-624MS  VF-200MS VF-23MS   VF-WAXms(最新！）

*VF-1MS:相当于DB-1MS、HP-1MS等GC柱和GC-MS柱，适用于烃类、胺类、酚类、农药、PCBs、挥发油、硫化物、二恶英等的分析。

*VF-5MS:相当于DB-5MS、HP-5MS等GC柱和GC-MS柱，适用于药物、芳烃类、酚、酯、生物碱、卤代烃、挥发油、杀虫剂等的分析

*VF-Xms：相当于AGILENT的DB-XLB柱。独特的固定相，是高亚芳基改性的低极性柱（比VF-5MS的极性稍强），使得它可以在高达340摄氏度条件下得到很低的基线。适用于农药、杀虫剂、PCBs、PAH、邻苯二甲酸酯类等的分析。

*VF-17MS：相当于DB-17MS等中等极性柱。适用于药物、农药、甾类等分析。（可达360度的应用上限）

*VF-35MS：相当于HP-35MS和DB-35MS，中等极性，但是经过高度灭活，很适合环境分：可用于分析有机氯、有机磷农药；EPA方法挥发性卤代物，EPA方法亚硝胺分析等。

*VF-200MS：相当于DB-200和 RTX-200，但是流失更低，耐温更高（可达350度），寿命更长。独特的极性柱，很适合取代芳香化合物的分析，如农业化学分析。对含硝基、卤素、羰基的化合物有独特的选择性。

*VF-23MS：相当于DB-23SP-2330和 RTX-2330，但是流失更低,寿命更长。由于采用100％的固化技术，它可以用绝大部分溶剂冲洗，而不引起固定液流失。特别适合FAME脂肪酸甲酯的分析。

*VF-DA:专用于痕量滥用药物分析（drugs of abuse）如尿液中的滥用药物的分析。由于VF-DA的超低流失，使痕量分析成为可能。

*VF-WAXms极性质谱毛细管柱：选择性和一般WAX(PEG20M)柱类似；超低流失带来的高灵敏    度，更高的信噪比；可以用于GC/MS的分析

05年推出的新品VF-1701MS，VF-624MS,VF-1301MS.同样具有优秀超低流失的品质
