开发了基于实时质谱的气味记录仪新样机。基于这个开发的系统，可以从可用的 m/z 中轻松获得一组对气味成分具有高选择性的传感器输出，从而可以在共线性最小化的情况下使用大量气味成分。此外，基于改进的气味混合方法，可以在宽动态范围内实时测量和再现气相目标气味。在记录过程中，以所有气味成分的质量模式作为数据库数据，并采用非负最小二乘法来估计目标气味的配方。结果发现，该系统仅使用一小组 m/z 即可在 25 秒内准确估计目标气味的配方，并且可以以与目标气味相同的气味印象再现气味。由此证实，基于所开发的气味记录仪可以实现大范围的气味实时记录。
The new prototype of odor recorder based on real-time mass spectrometry was developed. Based on this developed system, a set of sensor outputs with high selectivities to the odor components are easily obtained from the available m/z's so that a large number of odor components can be used with minimized collinearity. Moreover, the gas-phase target odor can be measured and reproduced in real-time with wide dynamic range based on the improved odor blending method. In recording process, the mass patterns of all odor components were used as the database data and the nonnegative least squares method was performed to estimate recipe of the target odor. It was found that this system could accurately estimate the recipe of the target odor within 25s using only small set of m/z's and could reproduce the odor with the same impression of smell as the target one. Thus, it was confirmed that the recording wide range of odor in real time could be realized based on this developed odor recorder.
