Abstract
Ena od prevladujočih analiznih metod v farmacevtski industriji je tekočinska kromatografija. Za potrditev istovetnosti analitov s pomočjo kromatografije ta analitska metoda zahteva primerjavo retencijskih časov analitov z retencijskimi časi standardnih substanc. Veliko število sorodnih substanc, ki jih je potrebno pri proizvodnji aktivnih farmacevtskih učinkovin spremljati s tekočinsko kromatografijo, zahteva veliko število primerjalnih standardnih substanc, to pa je stroškovno manj učinkovito. Pri rutinskih kromatografskih analizah se lahko v določenih primerih izognemo uporabi primerjalnih standardov, kar omogoči hitrejše analizne postopke ter boljšo stroškovno učinkovitost, saj nakupi dragih sorodnih substanc niso potrebni. Namen tega magistrskega dela je bil razviti kromatografsko metodo za določanje vsebnosti norfloksacina, enrofloksacina ter ciprofloksacina, izvesti njihovo pospešeno razgradnjo z različnimi reagenti, ter določiti faktorje občutljivosti in relativne faktorje občutljivosti nastalih sorodnih substanc na različnih koncentracijskih nivojih.

Abstract:
Liquid chromatography is one of the most powerful analytical methods in pharmaceutic industry. Identification of substances using chromatography requires retention time comparison of analyte and standard substance. Higher number of related substances, produced during synthesis of active pharmaceutical ingredients, must be analysed by liquid chromatography, therefore high number of standard substances are required which is not cost effective. Some routine analyses do not require standard substance usage, which enables faster analytical procedures and better cost effectiveness, because purchasing of expensive standard substances is not necessary. Objectives of this master thesis were development of chromatographic method for quantification of norfloxacine, enrofloxacine and ciprofloxacine, successful execution of forced degradation using different agents and determination of response factors and relative response factors of produced related substances on different concentration levels
