A novel approach for automation of Micro-Extraction by Packed Sorbent (MEPS), a solid phase extraction technique, is presented, enabling precise and repeatable liquid handling due to the employment of se- quential injection technique. The developed system was used for human urine sample clean-up and pre- concentration of betaxolol before its separation and determination. A commercial MEPSC-18 cartridge was integrated into an SIChrom™ system.The chromatographics eparation was performedonamonolithic HighResolutionC18(50_4.6 mm)column which was coupledon-line in the system with Micro- Extraction using anad ditional selection valve. A mixture of acetonitrile and aqueous solution of 0.5% triethylamine with acetic acid, pH adjusted to 4.5 in ratio 30:70 was used as a mobile phase for elution of betaxolol from MEPS directly onto the monolithic column where the separation took place. Betaxololwas quantified bya fluorescence detectoratwavelengths λex¼220 nmand λem¼305 nm.
