炼油厂和其他气体中轻质烃的测定，通常通过填充柱和机械旋转阀进行。例如，ASTM方法D-2597采用了这一办法。气体取样阀将少量计量后的样品气体，送入非极性填充柱。C1到C5碳氢化合物可从该色谱柱中洗脱，并进入第二个带有极性固定相的填充色谱柱。在这一点上，旋转阀被启动，以使载气反向流过预柱，并将该柱中的任何残余样品反冲至检测器，以测定样品中的总C6+含量。同时，C1至C5含量的色谱在第二个柱上进行分离、鉴定和定量。整个分析过程大约需要20分钟，由于色谱柱的正常变化，如何获得可接受的色谱分离通常是一个挑战。

挥发性有机化合物(VOCs)是空气污染的主要来源，此类物质的排放已受到严格管制，因其构成了主要或次要污染，如光化学烟雾。美国环境保护署（U.S. EPA）根据1990年《清洁空气法案》（CAA）对189种有害空气污染物进行了监管，其中51%为VOCs。本文详细介绍了PerkinElmer TurboMatrix™300 TD和PerkinElmer Clarus® 580GC在VOC监测方面的应用，及扩展目标合成物清单。本应用文献展示结果具有良好的重现性、线性和检出限。

本文描述的方法，基于原始ASTM® D-3606法，主要区别在于使用了毛细管柱。这种方法完全消除了乙醇的所有色谱干扰（甚至可以使用纯乙醇溶液），总体上提高了色谱质量，并显著缩短了分析时间（时间减少了50%或75%，具体取决于色谱柱设置）。

活性药物成分 (API) 的合成可能需要多个反应步骤，这些步骤会产生不良反应副产物或必须使用各种溶剂，需要从成品中剔除。这些溶剂和副产物可通过顶空气相色谱法进行测量，按照USP第467章挥发性残留有机溶剂分析方法。USP 467方法根据毒性将残留溶剂分成三类；除非有充分的理由，否则应避免使用1类溶剂，2类溶剂是因毒性问题而应限制使用的溶剂。

挥发性有机化合物（VOCs）是一系列具有高蒸气压的化合物，沸点在50至250摄氏度不等。这一特性使得大量分子倾向于从固态，蒸发或挥发为气态，融入空气。环境中的VOCs来源于多种渠道，包括人为和自然发生。在土壤中，VOCs主要来源于排放的工业和生活污水、石油泄漏和化学溶剂泄漏。定性和定量分析、监测土壤中的VOC污染至关重要，以确保减轻因VOC泄露而对健康造成的潜在负面影响。本研究中使用了Perkinelmer Clarus® GC/FID和Turbomatrix™ HS-40调查了土壤基质中的37种VOC

量的反应杂质也能够引起药物明显的稳定性问题，因为就重量和摩尔质量而言，辅料远超过API。痕量的反应产物也很容易超过多数药品关于降解产物低于0.2%的限量要求。辅料中的甲醛能够与药品降解产物中的初级和/或二级胺基团形成聚合物。也有报道指出，甲醛能够导致胶囊凝胶键合，从而引起药物体外分解的不利效果。由于醛类物质极高的活性，在药物的配方设计过程中，及时评估辅料中醛类物质的存在，对避免后续药物研发过程发生无法预料的稳定性问题至关重要。
