    Abstract: Systems and methods are provided for selectively filtering 1,2-diolein and 1,3-dioleine ions from an olive oil sample. An ion source is instructed to ionize a mixture of an olive oil sample and a pre-ionization modifier. The pre-ionization modifier includes silver (Ag). A differential mobility spectrometry (DMS) device is instructed to separate ions received from the ion source and affected by a post-ionization modifier based on ion mobility. The second post-ionization modifier is butanol, for example. The DMS device is instructed to selectively filter separated 1,2-diolein precursor ions by selecting a first compensation voltage (CoV) for the DMS device. The first CoV is specific to separate 1,2-diolein precursor ions from 1,3-diolein precursor ions. The DMS device is instructed to selectively filter separated 1,3-diolein precursor ions by selecting a second CoV for the DMS device. The second CoV is specific to separate 1,3-diolein precursor ions from 1,2-diolein precursor ions.

    Abstract: A personal liquid analysis system includes a portable liquid analyzer device, a mobile application as a user interface, and a cloud server for data analysis. The compact and portable liquid analyzer device is integrated by miniaturized near-infrared (NIR) optical sensors setup for spectroscopy measurement from a sample cell, control circuits, I/O user interface modules and wireless communication modules. The analyzer can be used to collect NIR spectra data from a liquid sample in the sample cell, and to transmit the data to a cloud server where compositional information is calculated, and presented to the user on the device and/or on a mobile application. The personal liquid analysis system enables the user to rapidly acquire qualitative and/or quantitative compositional information from liquid samples for a wide range of applications.

    Abstract: A general purpose device, system, and program perform colorimetric analysis by automatically comparing the color of an object to be analyzed with reference information. The device includes an imaging unit that takes images of the object to be analyzed; a memory unit that stores reference information of color information of the object in accordance with properties of the object; a conversion unit that makes the color space of the image data and the color space of the reference information the same by converting the color spaces when the color space of the image data of the object and the color space of the reference information are different; a determination unit that determines the properties of the object by comparing the color information of the image data and the color information of the reference information in a common color space; and a display unit that displays the determination results.
