“…Different devices such as SAW, molecularly imprinted polymer sensors [ 44 ], nano-bioelectronics [ 42 ], optical sensors [ 119 ], mobilized natural receptor sensors [ 120 ] and electrochemical biosensors [ 43 , 121 ] have shown suitable characteristics due to their compact structures, high sensitivity and fast response time [ 44 , 119 ]. In addition, ion mobility spectrum (IMS) [ 120 , 122 ] and organic printable electronic materials [ 45 , 48 , 123 ] with advantages of high sensitivity, simple apparatus, small volume and low cost, have shown great potential in standard E-nose technology, so the second challenge for E-nose technology is to investigate new materials and make it more portable and more sensitive with faster response times when exposed to different volatile species.…”

This paper provides a review of the most recent works in machine olfaction as applied to the identification of Chinese Herbal Medicines (CHMs). Due to the wide variety of CHMs, the complexity of growing sources and the diverse specifications of herb components, the quality control of CHMs is a challenging issue. Much research has demonstrated that an electronic nose (E-nose) as an advanced machine olfaction system, can overcome this challenge through identification of the complex odors of CHMs. E-nose technology, with better usability, high sensitivity, real-time detection and non-destructive features has shown better performance in comparison with other analytical techniques such as gas chromatography-mass spectrometry (GC-MS). Although there has been immense development of E-nose techniques in other applications, there are limited reports on the application of E-noses for the quality control of CHMs. The aim of current study is to review practical implementation and advantages of E-noses for robust and effective odor identification of CHMs. It covers the use of E-nose technology to study the effects of growing regions, identification methods, production procedures and storage time on CHMs. Moreover, the challenges and applications of E-nose for CHM identification are investigated. Based on the advancement in E-nose technology, odor may become a new quantitative index for quality control of CHMs and drug discovery. It was also found that more research could be done in the area of odor standardization and odor reproduction for remote sensing.

“…Using the mechanism of surface heating by radiation, for the conditions listed in the previous example, the heat radiating surface will need a temperature of up to 400 °C , which obviously has significant -131 -DOI: 10.5963/AMSA0303004 limitations related to the case of heating by conduction of the air gap. The effectiveness of surface radiative heating can be significantly improved by using a pulsed mode [11].…”

Abstract-The sampling unit of the device, based on ion mobility spectroscopy technique, for detection of ultra-small concentration of substances on human fingers and documents, is described. The vapor pressure of some substances is subtle; so the heating of an examined surface is a must for efficient detection of these substances. In the present work it was shown (by the thermal transfer investigation) that more efficient method of surface heating consists of the using of the impulse gas-discharge lamp in comparison with the use of a heated air flow or heat transfer from the warm body by thermal conductivity. However the heating of the human fingers by the irradiation of the gas-discharge lamp is not effective because of a small concentration of the melamine (pigment of the black or brown color) in the skin of the human palm. Therefore in this work the combination of the two methods is used: irradiation of the gas-discharge lamp heats grid and a grid heat the surface of the finger that is pressed to a grid. The system will be effective for the control of admission to public events and providing anti-terrorist measures [1-3].

Abstract-Ion Mobility Spectrometry (IMS) is a common technology used for rapid detection of trace amounts of explosives (mostly forming negative ions) and drugs (forming positive ions). Emergency chemically hazardous substances widely used in modern industry. Some emergency chemically hazardous substances form positive ions, others form negative ions. Therefore, for the detection of different substances in real time is required to apply the structure of two IMS-detectors. The article describes a device for the simultaneous detection of ions of both polarities with the ionization source based on a pulsed corona discharge. Authors investigated the advantages and disadvantages of such construction compared to unipolar cell in terms of sensitivity. Experimental results have demonstrated.
