Application of Sequential injection analysis in pharmaceutical analysis

SSUUMMMMAARRYY IINN EENNGGLLIISSHH This work is concerned on sequential injection analysis and its use in the field of pharmaceutical analysis. This flow method is a versatile, multi-purpose analytical system and for this is gaining more popularity in analytical chemistry. Firstly the review based on pharmaceutical applications was published. The new enhanced techniques such lab-on-valve, micro-SIA, bead injection and sequential injection chromatography was discussed. The experimental part is focused on the use of SIA for automation of long- lasting processes monitoring in pharmaceutical methods of analysis. Fully automated system for in vitro release testing of semisolid dosage forms was established. This test was based on Franz diffusion cell and its connection with SIA system. The system was tested for monitoring release profiles of three commercial preparations containing salicylic acid (Belosalic, Diprosalic, Triamcinolon S). The release profiles were statistically compared. The native fluorescence of salicylic acid was used for fluorimetric detection. Phosphate buffer pH 7.4 was the receptor medium, different membranes were tested. Samples were taken at 10 min intervals during 6 hours of the release test and each test was followed by calibration with five standard solutions. Other work was based on..
