介绍了一种廉价、可靠的嗅觉仪的设计。该设计对功能磁共振成像和电生理学研究人员有几个优势。这些优势包括相对较快的气味上升时间，计算机控制，多种气味管理，以及受试者附近没有铁质材料。此外，该设备是防污染的，而且由于空气既不温暖也不潮湿，它不太可能成为细菌的孵化器。嗅觉仪是由现成的层析部件组成的，几乎不需要改装。
A design for an inexpensive and reliable olfactometer is presented. The design has several advantages for fMRI and electrophysiology investigators. These advantages include relatively rapid odorant rise times, computer control, multiple odor administration, and no ferrous materials near the subjects. In addition, the device is contamination resistant, and, because the air is neither warmed nor humidified, it is unlikely to become an incubator for bacteria. The olfactometer is constructed of off-the-shelf chromatography parts that require little modification.
