Hollow fiber-based liquid-liquid-liquid microextraction combined with electrospray ionization-ion mobility spectrometry for the determination of pentazocine in biological samples.

A new method based on liquid-liquid-liquid microextraction combined with electrospray ionization-ion mobility spectrometry (LLLME-ESI-IMS) was used for the determination of pentazocine in urine and plasma samples. Experimental parameters which control the performance of LLLME, such as selection of composition of donor and acceptor phase, type of organic… CONTINUE READING
