A simple, rapid and cheap capillary electrophoresis-capacitively coupled contactless
conductivity detection (CE-C4D) method for determination of meldonium (MEL) in
urine samples was developed. Sample pretreatment was minimized to dilution of urine
samples with DI water and MEL was determined by CE-C4D in background electrolyte
consisting of 2 M acetic acid (pH 2.3) in ng mL−1 to mg mL−1 concentration range.
Sample-to-sample analysis time was less than 4 min, limit of detection and
quantification was 0.015 and 0.05 μg mL−1, respectively, and the method showed
excellent linearity (r2 ≥ 0.9998), recovery (97.6–99.9%) and intraday as well as interday
repeatability (RSD ≤ 4.7%).
