Determination of Sub-ppb Level of Phthalates in Water by Auto-SPME and GC-MS Application
نویسنده
چکیده
A solid-phase microextraction (SPME) method for the analysis of phthalates in water samples was developed on the CTC CombiPAL autosampler GC-MS platform. In this method, the sample preparation process was automated by using a CombiPAL autosampler, including the SPME fiber precondition, adsorption, and desorption, which improve the precision of the SPME method. The extraction temperature, extraction time, and salt-out effect are also studied. The optimized condition was applied to the analysis of real samples. The detection limits of the phthalates in this method are at the sub-ppb level.

Determination of Acrylamide in Selected Types of Iranian Breads by SPME Technique
ABSTRACT: Acrylamide is a chemical compound that has been widely used since the last century for various applications. It is also formed from carbohydrate and amino acid containing foods by application of heat particularly in fried potato products, coffee and bread. Since bread is one of the primary foods of Iranian people, the determination of acrylamide content in bread might be considered im...
متن کاملHCl- Etched Steel Fiber for Determination of Phthalates in Water Samples by Solid-Phase Microextraction
In the present work, a stainless steel wire was etched by hydrochloric acid during a chemical etching process. The obtained black layer on the surface of the fiber was used as sorbent for extraction of trace amount of phthalates in the aqueous samples by solid phase microextraction. New fiber efficiency was investigated using a home-made solid-phase microextraction (SPME) device and gas chr...
متن کاملDetermination of 17 kinds of banned organochlorine pesticides in water by activated carbon fiber-solid phase microextraction coupled with GC-MS.
Activated carbon fiber (ACF) as extraction fiber for solid-phase microextraction (SPME) and its application for the analysis of banned organochlorine pesticides (OCPs) were investigated. Firstly, ACF was activated by different concentration of zinc chloride, which indicated that ACF activated by 60% zinc chloride had a reasonable specific surface area, pore volume and pore distribution. Secondl...
