In the actual contribution, a simple process was developed and optimized for effective IS addition and DBS elution. A group of acidic and/or basic drugs, with different chemical characteristics, was added to the collected capillary blood in different ways and the mixture was transferred onto the DBS collection card (903®Whatman™). Various elution procedures were also examined and are discussed. Direct injection of the eluted DBS sample into CE-UV ensured a rapid and reliable determination of the drugs without the need for any additional pretreatment steps (extraction, preconcentration). The contents of analytes in the dissolved eluates were determined and recoveries >70% were achieved for the optimized elution systems with satisfactory repeatability (RSD <5%).
