Abstract: Изобретение относится к области аналитической химии, а именно к способам определения подлинности (натуральности) и выявления фальсификации эфирных коричных масел с применением метода масс-спектрометрии изотопных соотношений. Способ определения подлинности и выявления фальсификации эфирных коричных масел заключается в том, что методом газовой хроматографии-сжигания/пиролиза-изотопной масс-спектрометрии определяют изотопный состав углерода и водорода компонентов коричного эфирного масла (линалоола, коричного альдегида, эвгенола, кариофиллена, цинамилацетата, бензилбензоата), полученные результаты представляют в виде изотопных профилей и сопоставляют с предварительно установленными изотопными профилями углерода и водорода, характерными для подлинных коричных масел корицы и кассии: при совпадении профилей образец коричного масла считают подлинным, а в случае несовпадения или выпадения значений изотопного состава углерода или водорода одного или нескольких компонентов из профиля-фальсифицированным. Разработанный способ позволит определять подлинность эфирных коричных масел и выявлять их фальсификацию разного вида: путем добавления компонентов, извлеченных из других растений, разбавления синтетическим коричным альдегидом или путем подмены эфирного масла корицы более дешевым маслом кассии при сокращении продолжительности анализа до 25 минут и повышении достоверности определения за счет анализа большого массива данных для установления изотопных профилей подлинных коричных масел (34 образца). 11 ил., 3 табл.

Abstract: FIELD: medicine.  
     SUBSTANCE: invention relates to medicine, namely to methods for positioning a fiber-optic probe for precision optical diagnostics of hemodynamics and oxygen regime of periodontal tissues. The method is based on CAD technology and is as follows. With the help of a dental intraoral scanner, the patient’s dentition and the mucous membrane of the alveolar process are scanned. The resulting digital models are stored on a computer in the STL or PLY format. With the help of CAD technology in the computer program “EXOCAD” for 3D design in dentistry, the boundaries of the area of interest for research are set on digital models. The thickness of the positioner is 4 mm, the uniform separation of the surface of the positioner with the mucous membrane is 0.5 mm to eliminate pressure on soft tissues. Next, cylindrical holes are designed corresponding to the dimensions of the diameter of the fiber-optic probe, located perpendicular to the surface under study. At the base of the cylinder facing the surface of the study, a 0.2 mm thick ledge is set to fix the fiber-optic probe at a distance of 0.7 mm to the surface under study. The finished project is saved on the computer in the STL format and sent for 3D printing with a biocompatible photopolymer resin that does not pass sunlight. Then, using a printed positioner, the fiber-optic probe of the LAKK-M device is fixed in the oral cavity into the cylindrical holes of the positioner to the ledge.  
     EFFECT: increase in the reliability of the results is achieved by eliminating the pressure of the positioner and the probe on the mucous membrane and eliminating artifacts due to the stable retention of the fiber-optic probe.
