Název v původním jazyce

Sensitive Detection and Separation of Fluorescent Derivatives using Capillary Electrophoresis with Laser-Induced Fluorescence Detection with 532 nm Nd:YAG Laser

Popis výsledku v původním jazyce

Capillary Electrophoresis with Laser Induced Fluorescence detection (CELIF) is a powerful tool for separation and sensitive determination of fluorescent compounds. Biologically active compounds, such as amino acids, peptides and proteins may exhibit native fluorescence, which is however often low and/or an expensive laser is required for excitation in UV. Therefore, labeling of the analytes with a fluorescent dye is usually necessary. In this work, home-built CELIF instrument was developed and tuned upusing rhodamine-based dyes with diode pumped frequency-doubled continuous wave Nd:YAG excitation laser with feedback power regulation (532 nm). First, the suitability and performance of this type of laser for LIF detection in a separation method was evaluated. Detection limit of 2E-13 M was achieved with rhodamine B, which is comparable to previously described CELIF with Ar+ laser. An exemplary separation of rhodamine dyes is given. Rhodamine based derivatizing agent was chosen for label
