Segons les característiques del problema analític es triarà un o altre tipus de mètode d'anàlisi. Quan l'objectiu és saber què hi ha en una mostra desconegu

Abstract:

The coherent body of research described in the existing published work is concerned with new assay method development and validation using novel systematic approaches for pharmaceutical and diagnostic compounds. The first stage of the research was to study how analytical method development and validation are typically carried out at present and to formulate this into a simple step-by-step approach. Such a template and protocol was not only used as the foundation of this research programme but could also serve as a simple systematic guide for other practitioners and those new to the field. Furt

Abstract:

This thesis describes the design, construction, and evaluation of a series of LED array photolysis systems for high throughput photochemistry. Three generations of array systems of increasing sophistication are evaluated using calorimetric measurements and potassium tris(oxalato)ferrate(III) chemical actinometry. The results are analyzed using descriptive statistics and analysis of variance (ANOVA). The LEDs in the third generation array were shown to be statistically equivalent, with respect to light output, according to physical and chemical actinometry experiments. The third generation

Abstract:

Cromolyn sodium (CS) is a mast cell stabilizer which has been used to treat systemic mastocytosis, allergic- and exercise-induced asthma, and allergic reactions induced by atopic dermatitis. Presently, CS is administered orally and intranasally, and with a short half-life and poor absorption, 4 to 8 doses are required daily for treatment. Developing a transdermal product for CS would eliminate such drawbacks that lead to inconsistent patient dosing and provide sustained therapeutic effects when administered via skin. Our long-term goal is to determine the feasibility of delivering CS through s

Food and drinking water are the principal routes of exposure to arsenic (As) for humans. More than 50 different naturally occurring As-containing compounds have been identified. Regarding the toxicological aspects of arsenic in food, inorganic arsenic (iAs, (arsenite or As(III) and arsenate or As(V)) is considered to be the most dangerous form and is classified as a nonthreshold, class 1 human carcinogen. The organic forms are mainly considered to be non-toxic. Therefore, species-dependent differences in toxicity must be considered when establishing the maximum tolerated levels in food directi

Nackdelen med detta är att det tar väldigt lång tid innan man ser något resultat. En annan effekt av bakterierna är att stärkelsens viskositet blir lägre, dvs. vätskan blir mindre trögflytande.

Abstract:

The revision of the CEN/TR 15522-2:2012 methodology contains new biomarkers to facilitate forensic fingerprinting of the variety of oil types that can be a part of different crimes and the purpose of this project is to validate the biomarkers of the new methodology. Biomarkers were validated by examining corresponding diagnostic ratios compatibility with the internationally used sampling cloth, discriminating power, correlation and simulated weathering sensibility through GC-SIM-MS analysis followed by statistical evaluation with t-tests, diagnostic power, Pearson correlation matrices and MS-P

Abstract:

Diet assessments are critical for understanding the foraging behaviour, habitat use and trophic separation of mammalian predators and are vital for gaining insight into how predators influence prey populations. The aim of this research was to qualitatively describe the diet of black-backed jackals (Canis mesomelas, Schreber 1775) using scat analysis on two contrasting land-use types in the Eastern Cape Province, South Africa. Scats were collected on a monthly basis from November 2009 to October 2010 from two game reserves (Great Fish River Reserve and Shamwari Private Game Reserve) and two nei

Abstract:

O urânio (U) é considerado um elemento poluente do ambiente devido à sua toxicidade química e radiológica, com propriedades cumulativas em seres humanos, podendo causar diversos tipos de doenças no organismo. Consequentemente, há um grande interesse na determinação de U em amostras ambientais devido às ações antrópicas como as emissões desse elemento na mineração, nas indústrias e em acidentes nucleares que ocasionam alterações dos seus teores no meio ambiente. Dentre as diversas metodologias analíticas para a determinação de U em amostras ambientais, destaca-se a análise por ativação com nêut

Secondly, the acquired knowledge is used to develop, validate and execute new methods for phase characterization in liquid chromatography. The methodology used in this thesis is a combination of experiments, fundamental nonlinear theory and systematic computer simulations.

Abstract:

Performing quantitative analysis of targeted bioactive compounds in biological samples, such as blood plasma, cerebrospinal fluid or extracts from pig liver, put high demands on the ruggedness of the method acquiring the results. In addition to the complexity of the sample matrix, the bioactive compounds targeted for analysis usually have low levels of natural abundance, further increasing the demand on the analytical method sensitivity. Furthermore, quantitation of analytes at trace levels in the presence of large amounts of interfering species in biofluids must aim for repeatable precision,
