Development of Cold Fiber Head Space Solid-Phase Microextraction for Analysis of 2,5 Hexandion in Urine

Abstract

2,5-Гександіон (2,5-ГД), основний метаболіт н-гексану, був вилучений із зразків сечі з використанням твердофазної мікроекстракції на основі холодного волокна (CF-HS-SPME) та проаналізований за допомогою газової хроматографії з детектором йонізації полум'я (GC-FID). Важливі параметри для підвищення ефективності сорбції волокна, включаючи об'єм зразка, час екстракції та температуру, оптимізовані за допомогою центрального композиційного плану експерименту. Встановлено оптимальні умови, за яких визначено межу чутливості та відносні стандартні відхилення. Показано, що розроблений метод є швидким, чутливим та простішим у порівнянні із звичайними методами кількісного аналізу 2,5-ГД у зразках сечі. 2,5-Hexanedione (2,5-HD), the main metabolite of n-hexane was extracted from urine samples using cold fiber head space solid-phase microextraction (CF-HS-SPME) based on thermoelectric cooling and analyzed with gas chromatography equipped with a flame ionization detector (GC-FID). Important parameters for improved efficiency of fiber sorption including sample volume, extraction time and temperature were optimized using a central composite design. The optimum conditions were determined, under which the detection limit and the relative standard deviations were found. The method was shown to be rapid, sensitive and easier than conventional methods for quantitative analysis of 2,5-HD in urine samples.
