Abstract (sommario):
The development of the oil and gas complex is one of the priority areas of the Azerbaijan economy. Oil and gas are among the most competitive Azerbaijan goods and are in high and stable demand from global consumers. Therefore, increased attention is paid to product quality. One of the methods for quality control of petroleum products is gas chromatography. Today it is a widely used physical and chemical research method. The capabilities of a gas chromatography are mainly determined by the enormous separating power of the chromatographic columns and the characteristics of the detectors. If the chromatographic column is sometimes called the heart of the chromatograph, then the detector can be called the brain of the chromatograph [1,2]. Effective development of an analysis technique, its successful implementation, troubleshooting of a chromatograph, and metrological certification are impossible without the ability to make the right choice of a detector, operate it competently, and correctly interpret the detector signal. About 50 detectors have been proposed for gas chromatography, but only a few of them are used in practice. The most used are the flame ionization detector and the thermal conductivity detector. The article shows the advantage of using a flame ionization detector to measure important physical and chemical properties, such as density, caloric content, the ratio of the number of carbon atoms to the number of hydrogen atoms C/H. Keywords: Chromatography, gas-mixture, density, hydrocarbon, heat of combustion, calorific value, flame ionization detector, number of carbon atoms, sensitivity, quality.

Abstract (sommario):
Currently, liquid chromatography is widely used for the analysis and determination of water-soluble vitamins (WSVs) in functional foods. However, due to the diversity of sample characteristics and the requirement for purification accuracy, the chromatographic conditions and specific methods used vary. This paper reviews the chromatographic conditions of liquid chromatography techniques for detecting WSVs in food, as well as the selection of liquid chromatography methods in different application fields. The chromatographic conditions include chromatographic columns, column temperature, mobile phase, flow rate, and elution gradient, and the application scope of different chromatographic conditions is compared. Liquid chromatography methods include high-performance liquid chromatography and liquid chromatography-tandem mass spectrometry, and discussions are made on the applications and prospects of these two methods under different chromatographic conditions. Therefore, this review provides research insights into different chromatographic conditions and methods for food quality inspection and biochemical analysis research.

Abstract (sommario):
Abstract Substituted uracil herbicides injected into a gas chromatograph react with trimethylanilinium hydroxide to give iV-methyl derivatives with good gas chromatographic properties. Maximum methylation is obtained when the molar ratio of methylating reagent to herbicide is ca 4:1. This technique for preparing derivatives provides rapid qualitative and quantitative chromatography of the substances examined. Chromatographic response was linear with increased concentration for the synthetic standard and the on-column product of uracil herbicide. The proposed derivatization method was used to analyze herbicides in formulations. The methyl derivatives were identified spectroscopically

Abstract (sommario):
La chromatographie à contre courant (CCC) est une technique de purification chimique préparative quitravaille avec un système biphasique liquide. Une phase est la phase mobile, l'autre phase est la phasestationnaire. Il n'y a aucun support solide: un champ de force centrifuge est utilisé pour maintenir en place laphase stationnaire. Ce travail est une contribution à l'étude de la purification préparative par CCC. Après uneimportante étude bibliographique des procédés de purification en continu tant en CCC qu'autres, il est montréque la méthode dite "multi-dual-mode", ou MDM, est une solution possible. Elle consiste à utiliser le fait queles deux phases liquides peuvent servir de phase stationnaire: il suffit d'inverser le sens de circulation et lanature de la phase mobile (méthode dual-mode). Le mélange est séparé de façon classique pendant untemps chronométré, puis on inverse le rôle des phases: la phase mobile devient stationnaire et vice versa eton inverse également le sens de circulation (ascendant devient descendant ou vice versa). On sort lescomposants du mélange soit d'un coté de la colonne CCC, soit de l'autre. La méthode est mise en oeuvrepour purifier le Bleu de Coomassie en le débarassant des ses composés polaires (d'un coté) et apolaire (del'autre coté de la colonne et en accumulant dans la colonne la fraction de polarité intermédiaire, fractiond'intérêt. Une nouvelle colonne hydrostatique de petit volume (30 mL) a également été testée: elle permetde tester un nouveau système liquide très rapidement
Counter-current chromatography (CCC) is a preparative purification technique that works with the twoliquid phases of a biphasic liquid system. One phase is used as the mobile phase when the other phase isused as the stationary phase. There is no solid support: centrifugal fields are used to obtain a support-freeliquid stationary phase. This work contains an exhaustive bibliographic study of what can be found in theliterature concerning continuous chromatographic processes. The multi-dual-mode (MDM) process was foundto be the best one able to purify large amount of crude mixtures. The MDM method starts with a classicalseparation of the mixture followed by a switch of both the liquid phase nature and the flowing direction. Themobile phase flowing e.g. in a descending direction becomes the stationary phase. The previous stationaryphase becomes the mobile phase flowing in the ascending direction (or vice versa). The purified compoundsof the introduced mixture are eluted at one side of the column or the other according to their polarity. TheMDM method was used to purify a crude sample of Coomassie Blue: the polar part of the dye was eluted atthe column top (or head) and the apolar part at the column bottom (or tail) while the essential part of the dyewas trapped inside the CCC column. The work also presents a new small volume (30 mL) hydrostatic CCCcolumn. It is shown that this column could be used to test quickly the potential of a given biphasic liquidsystem

Abstract (sommario):
Four mechanisms were considered as possible causes of the loss in resolution for a Dionex CG2 ion chromatography resin: 1) presence of inorganic ions strongly bound to the active sites; 2) adsorption of organic species; 3) physical alterations; and 4) chemical alterations. The instrumental analyses used to gather data were ICP, FT-IR, SEM, solid C-13 NMR and IC. Based on the results, no metal ions are bound to the resin, no organic species are held onto the resin, and no physical change was observable. The cause for the loss of resolution is a strong reduction in the number of active sites in the resin as confirmed by elemental analysis for the sulfur in the sulfonic acid present in the active sites.

Abstract (sommario):
The objective of this work has been to develop an understanding of the changes in volumetric flow rate that occur during chromatography so that flow rate measurements can be used as the basis of an analytical method. It is suggested that the total amount of gas which adsorbs on a column equals the total amount of gas which elutes from the end of the column.

Abstract (sommario):
A tandem purification procedure was developed by a combination of metal chelate and affinity chromatography. The conditioned medium from different cell lines producing tissue plasminogen activator was first chromatographed on a zinc chelate-agarose column equilibrated with low ionic strength buffer. After thorough washing, the column was connected to a lysine-agarose column, previously equilibrated with the same buffer. Tissue plasminogen activator was eluted from the zinc chelate column by a gradient of imidazole and the effluent was allowed to flow through lysine-agarose matrix. The two columns were disconnected and after thorough washing, the bound enzyme from lysine-agarose column was eluted with a linear gradient of potassium thiocyanate in the equilibration buffer. This method resulted in a purification factor which varied between 40 to 110 fold. The purity of the isolated enzyme was assessed by sodium dodecyl sulphate-gel electrophoresis and fibrin zymography. The chromatographic procedure described provides a novel method for the rapid purification of tissue plasminogen activator to a high degree of purity.

Abstract (sommario):
The natural gas industry currently relies on gas chromatography to evaluate the composition of natural gas including alkanes, carbon dioxide, nitrogen, and oxygen. The higher and lower heating values, Wobbe Index, Hydrocarbon Dewpoint, Methane Number, and viscosity are all calculated from the gas composition. The need to understand the composition of fuel gas and to monitor its components is crucial to the natural gas industry. Monitoring the composition of the fuel gas provides the industry with the capability of protecting valuable underground assets, delivering gas that meets end-usage requirements, and tracking of constituents for both billing purposes and to ensure compliance with tariff agreements. As with any technology, there are limitations to gas chromatography. Limitations can include high cost, time delay, inability to sample at high pressure, and selectiveness of gas chromatography detectors. This project consisted of a technology assessment of currently available and emerging technologies including micro gas chromatographs, optical spectrometers, and mass spectrometers for their ability to determine gas composition compared to current GC technology. Technologies were investigated and assessed by their analytical characteristics (what components they could analyze and detection limits), their sampling characteristics (sampling pressure limits, scan time, and emissions), and their operational characteristics (availability, cost, consumables, maintenance, and packaging). Recommendations for further testing were made on the technologies whose characteristics showed the most promise for analysis of natural gas at custody transfer points.
