Background Polyamines present in human body are frequently considered as markers of occurrence of cancer. Therefore, the availability of simple and efficient method for determination of their level in body liquids and tissues is of some interest. Methods Supported liquid membrane technology coupled with HPLC seems to be an appropriate technique to follow the level of polyamines in human blood and...
Sample pre-treatment is a very important step in many analytical procedures, especially when the analyte is presented in low concentration in complex sample matrices. In this paper, potential using of the supported liquid membrane (SLM) technique as a sample preparation step in order to isolate, pre-concentrate and separate small peptides and phosphono dipeptides from aqueous solutions and body fluids...
Istotny element procedur analitycznych dotyczących skomplikowanych mieszanin jakimi są próbki środowiskowe bądź biologiczne stanowi wstępne wyodrębnienie, oczyszczenie i zatężenie analizowanej substancji. Do tego celu coraz częściej stosuje się sorbenty polimerowe i układy membranowe. W niniejszym przeglądzie przedstawiono najważniejsze i najczęściej używane metody przygotowania próbek środowiskowych...
