… som användes var, en spektrofotometrisk metod ”Hope bitterness in beer” och en HPLC metod ? Iso ?-, ?-and ”-acid in hope and isomerized hop extracts in beer”. Under arbetets gång fastställdes det att tillredningen av extraktionslösningarna i den spektrofotometriska metoden är …
… cloud point. This project aims to validate and if necessary modify an existing HPLC method for quantifying two out of three key components (A, B and C) in the conditional emulsion. Attempts to develop a method to quantify the pH adjusting components, X and Y were also made …

… basis of previous information about the extract. The other method uses a RP- HPLC where ellagic and gallic acid were used as standards. The amount ellagic acid in the extract was determined to 0,06 %, but the result from gallic acid was inconclusive. Further analysis is …

… extract from new shoots. Chemical analyses on the salix extract were made by HPLC ? DAD combined with a fluorescence detector. Ester hydrolyses was performed on all samples. Detection was then possible and certain chemical substances were distinct. The following substances were …
… and methylphenidate) and their metabolites. The analyses were performed with HPLC-UV with columns whose stationary phases were based on macrocyclic glycopeptides (Chirobiotic V, V2 and T) and polysaccharides (Lux Cellulose-1, Cellulose-2 and Amylose-2). The Chirobiotic V column …
… and methylated catecholamines were developed by analysis of 46 samples using HPLC. Creatinine was analysed in acidified urine in order to see if the results became the same as when analysed in non-acidified urine. Urinary catecholamines and methylated catecholamines were …
Denna examensrapport redogör för en metodutveckling av aminotransferase aktivitet som är utförd för Medipharmv AB i Kågeröd som tillverkar Enzobact. Enzobact är en bakteriekultur som består av värmebehandlad Lactobacillus helveticus och används vid tillverkning av lågfetthaltiga …
… med en ny metod som heter denaturing high performance liquid chromatography (DHPLC). Metoden bygger på separation av PCR (polymerase chain reaction) amplifierade 16S rDNA fragment i DHPLC [8]. Vid identifiering av bakterier amplifierades olika variabla regioner från 16S rRNA …
… compared to the results from the presently used methods, Kleihauer-Betke and HPLC. Cord blood was diluted with venous blood from an adult with the same blood group in various concentrations. A number of tests were performed and showed a fairly good correlation between the …
… was conducted by reverse phase high performance liquid chromatography (RP-HPLC). For identification of the peptides, on-line electrospray ionisation mass spectrometry (ESI-MS) was monitored. Suggested identities of the peptides were given by using MS/MS analysis of the most …

… analyses of itraconazole were made by high performance liquid chromatography (HPLC). Pharmacokinetic parameters obtained in this study indicate that itraconazole, from a pharmacokinetic aspect, is suitable for treatment of equine mycosis, considering the long treatment often …
… was incubated in horse plasma and the amount of PABA formed was measured by HPLC analysis. The results showed a tendency that the horses suffering from adverse reactions had a lower activity of procaine hydrolysis compared to the control group. The difference was not …
… and addition, respectively, of ascorbic acid. The samples were analysed with HPLC both before and after the extraction phase of the FC method. The results show a decrease in ascorbic acid of approximately 21 % after extraction compared to before. This study showed that the FC …
… mätningarna tar ofta lång tid att genomföra. Högupplösande vätskekromatografi, HPLC, är en kromatografisk teknik som har utveckats från att vara en ganska tidsödande metod för att mäta bara skatol och indol till att bli relativt snabb och passa även för mätningar av androstenon …
