Solid phase microextraction (SPME) - theoretical and practical aspects
Języki publikacji
Abstrakty
W pracy przedstawiono aspekty teoretyczne i praktyczne techniki mikroekstrakcji do fazy stacjonarnej (SPME). Z uwagi na swoje liczne zalety metoda ta jest przez analityków coraz częściej stosowana. Stosuje się ją zarówno do analizy próbek środowiskowych (powietrze, woda, gleba) jak i w analizie żywności i materiałów bilogicznych. Jej wysoka precyzja, prostota i mała czaso- i pracochłonność jest powodem zalecania przez autorów tej pracy do wprowadzania techniki SPME w życie.
In recent years, much attention in analytical chemistry has been paid to sample preparation techniques, especially those which minimize the consumption of organic solvents. One on the most promising of these, solid phase microextraction (SPME), is presented in both its theoretical and practical aspects. SPME is a fast, solventless alternative to conventional sample extraction techniques. SPME greatly reduces analysis time and improves minimum detection limits, while maintaining resolution. SPME integrates sampling, extraction, concentration and sample introduction into a single solvent-free step. Analytes in the sample are directly extracted and concentrated to the extraction fibre. The method saves preparation time and disposal costs and can improve detection limits. It has been routinely used in combination with gas chromatography (GC) and GC/mass spectrometry (GC/MS) and successfully applied to a wide variety of compounds, especially for the extraction of volatile and semi-volatile organic compounds from environmental, biological and food samples. By controlling the polarity and thickness of the coating on the fiber, maintaining consistent sampling time, and adjusting several other extraction parameters, an analyst can ensure highly consistent, quantifiable results from low concentrations of analytes.
