Gas chromatographic analysis system with mass spetrometric and olfactometric detection

天然香料的生物技术生产及其分析是吉森尤斯图斯·李比希大学食品化学和食品生物技术研究所研究活动的主要重点。为了有效和有针对性地执行当前和未来的研究活动，需要一种分析仪器，能够对挥发性物质（主要是食品成分）进行高灵敏度和选择性的痕量分析，同时进行嗅觉检测。气相色谱仪耦合串联质谱仪和嗅觉检测器端口特别适合于这项任务。该设备具有强大的自动进样器，热脱附单元，固相微萃取选项以及动态顶空萃取模块，可实现最先进的无溶剂取样和进样技术，并保证设备的有效利用。

The biotechnological production of natural flavourings and their analysis represent a major focus of the research activities of the Institute of Food Chemistry and Food Biotechnology at the Justus Liebig University of Giessen. For an efficient and targeted execution of current and future research activities, an analytical instrument is required which enables the highly sensitive and selective trace analysis of volatile substances, mainly food ingredients, with simultaneous olfactometric detection. A gas chromatograph coupled to a tandem mass spectrometer and an olfactometric detector port is particularly suitable for this task. The equipment with a powerful automatic sampler, a thermodesorption unit, an option for solid phase microextraction as well as a module for dynamic headspace extraction enables state-of-the-art solvent-free sampling and injection techniques and guarantees the efficient utilization of the device.
