Abstract:

L’analyse des extraits naturels est de nos jours réalisée à l’aide de nombreuses techniques d’analyse plus ou moins complexes. Parmi ces techniques, l’HPTLC est bien connue en tant qu’outil d’identification phytochimique. Le but de cette thèse a été d’étudier l’apport de cette technique dans l’analyse des extraits naturels en dehors de son aspect « identification ». Ce travail a conduit à différentes études permettant de mettre en évidence des applications peu connues de l’HPTLC comme par exemple son utilisation comme technique semi-preparative. De plus, sa capacité à avoir une phase stationna

Abstract:

Chemistry<br>Ph.D.<br>High Pressure Liquid Chromatography (HPLC) is a well-known and widely used analytical technique which is prevalent throughout the pharmaceutical industry as a research tool. Despite its prominence HPLC possesses some disadvantages, most notably slow analysis time and large consumption of organic solvents. Ultra Pressure Liquid Chromatography (UPLC) is a relatively new technique which offers the same separation capabilities of HPLC with the added benefits of reduced run time and lower solvent consumption. One of the key developments which facilitate the new UPLC technology

Abstract:

High Performance Liquid Chromatography (HPLC) is a widely used tech-nique both for detecting and purifying substances in academy and in the industry. In order to facilitate the use of, and knowledge in HPLC, character-ization of stationary phases is of utmost importance.

Abstract:

The effects of transition metal ions as components of the mobile phase on the retentions in HPLC of 2-aminophenol and selected α-diketones were studied on both ODS-silica and porous polymer columns. The compounds were used as model compounds in an investigation which set out to derive a detailed understanding of the mechanisms Involved when metal ions are used to selectively modify the retention of compounds capable of interaction. This technique, which has parallels with ion-pair chromatography, provides another method by which the conditions of a separation may be altered and the selectivity

Malaria remains one on the world's most common infectious diseases with 300 to 500 million cases every year. The current treatment of malaria is restricted due to ever increasing drug resistance, cost of treatment and the availability of treatment. When looking at solutions for these problems, new drug delivery systems should be taken into consideration. The Pheroid™ drug delivery system which incorporates Pheroid™ technology can be placed in this category and the stability of anti-malarial drugs in combination with the Pheroid™ drug delivery system was investigated.

Lysophosphatidic acid (LPA) is a bioactive lipid with a plethora of biological functions, including roles in cell survival, proliferation, and migration. Although high-performance liquid chromatography electrospray ionization tandem mass spectrometry (HPLC ESI-MS/MS) technology has been used to measure the levels of LPA in human blood, serum and plasma, current methods cannot readily detect the minute levels of LPA from cell culture. In this study, a novel HPLC ESI-MS/MS method with enhanced sensitivity was developed which allows accurate measurements of LPA levels with a limit of quantitation

Limited information is available regarding the behaviour and fate of this pesticide in the environment, and therefore, various studies are required in this field. In such studies, analytical methods for the determination of 1,4-DMN in the different environmental samples are a core element. This

La concentration maximale fixée par les pays de l'union européenne, pour tout pesticide présent dans les eaux destinées à la consommation humaine, est de 0,10 g/l. Pour atteindre ces limites, il faut pouvoir doser des teneurs 2 à 3 fois inferieures, ce qui implique de travailler en limite de sensibilité des méthodes conventionnelles de chromatographie. Dans un souci d'assurance de la qualité des résultats, nous avons évalué, dans un premier temps, les apports d'une technique dite, multi-méthodes, qui associe une méthode clhp multi-résidus à des méthodes cg plus spécifiques.

Abstract:

“Green” explosives are an important sub-family of explosives due to the banning of explosives based on heavy metals, such as lead azide and lead styphnate, according to the REACH list. A substitute to lead azide is potassium 4,6-dinitrobenzofuroxane (KDNBF) which is an alternative “green” explosive. Hence there is an upcoming need for analytical and quality control protocols for KDNBF. In this report is HPLC-UV/VIS, GC-FID and potentiometric titration evaluated for their suitability as methods for testing of KDNBF. The results implies that KDNBF can be analyzed by GC-FID, when dissolved in DMS
