摘要： The invention involves the detection of odors using an odor detector including an n-type semiconductor sensor having an electric resistance responsive to odor molecules adsorbed thereonto. An ozonizer is provided within a test compartment to contact the detector with an ozone gas for the purpose of calibrating the detector to an initial zero setting. The test compartment also includes a ventilation fan operable to draw purging air into the compartment. In order to minimize the time required to bring the detector to the initial zero setting, a computer is used to selectively actuate the ozonizer and the ventilation fan in a controlled manner. Before starting a new detection cycle, an operator selects a specific table of optimal pattern for quick recovery to the zero setting from among a plurality of tables stored in the computer, based on certain factors such as the identity and concentration of previously detected odorant substances, etc.

摘要： The invention involves the measurement of the total concentration of odors of an article such as foodstuff, fruits and beverages as an indication of their specific quality such as freshness and maturity. An odorimetric device includes a non-selective odor detector disposed within an odorimetric chamber and a heater means for heating the odor detector to a predetermined operating temperature. The odor detector is comprised of a sintered body or film of a highly purified n-type metal oxide semiconductor formed on a substrate by vapor deposition. In one embodiment, the total concentration of odors of an object that is monitored as a function of time may be compared with a reference value or pattern to evaluate the quality of the object. In a second embodiment, the odor detector is comprised of a plurality of like odor detector elements with their sensing characteristics staggered due to different operating temperatures set by their associated heater elements, each odor detector element generating a signal indicative of the total concentration of the odors. The use of this composite odor detector enables a more reliable determination of the quality of an object in reference to a reference object.

摘要翻译： 本发明涉及测量诸如食品，水果和饮料的物品的气味的总浓度，作为其特定质量如新鲜度和成熟度的指示。 气味测定装置包括设置在气味室内的非选择性气味检测器和用于将气味检测器加热到预定操作温度的加热器装置。 气味检测器由通过气相沉积形成在基板上的高度纯化的n型金属氧化物半导体的烧结体或膜构成。 在一个实施例中，作为时间的函数监视的对象的气味的总浓度可以与参考值或图案进行比较以评估对象的质量。 在第二实施例中，气味检测器由多个类似的气味检测器元件组成，其感测特性由于其相关联的加热器元件设置的不同操作温度而交错，每个气味检测器元件产生指示气味总浓度的信号 。 使用该复合气味检测器可以参考参考对象更可靠地确定物体的质量。
