Analysis on a New Four Quadrant Switch Mode DC-DC Converter
ISBN: 9783659207280 / Angielski / Miękka / 2012 / 84 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. A new topology has emerged out of the research to provide four quadrant operation of a high frequency dc-dc converter having one supply source and easy gate pulse control. This new topology has been developed out of switching dc-dc converters with voltage lift circuits; its operational range is wide at high conversion efficiency, whereas, the present four quadrant switching dc-dc converters conversion efficiency decreases around the operation of a particular duty cycle. The result is a single source topology switched by conventional ON/OFF duty cycle control as used in other high power...

Easy Ways to Understand HPLC, UV and Method Validation Parameters
ISBN: 9783659402395 / Angielski / Miękka / 2013 / 52 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. High-pressure liquid chromatography (HPLC) used in the analytical development to quantify the biological sample concentration, the active pharmaceutical ingredient (API) and to evaluate the impurity and degradation product profiles of the drug substances (DS) and drug products (DP). Additional uses of HPLC include determination of content uniformity of dosage form, monitoring of dissolution profiles, determination of antioxidants and preservative content and supporting of cleaning validations. UV spectroscopy is one of the most frequent used techniques in pharmaceutical analysis. It involves...

HPLC Method Validation of Trimetazidine and its Pharmacokinetic Study
ISBN: 9783848421411 / Angielski / Miękka / 140 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. The objective of the present study was to develop and validate a HPLC method with good sensitivity and specificity for the identification and quantification of trimetazidine in human plasma. Trimetazidine and caffeine (internal standard) were isolated from plasma samples by protein precipitation with methanol. The chromatographic separation was accomplished on a Xterra C18 Column with the mobile phase consisting of potassium di-hydrogen phosphate buffer-acetonotrile-triethylamine (90:10:0.04, v/v) (pH 4.16, adjusted with ortho-phosphoric acid), and the flow rate was set at 1.0 mL/min....
