The fiber SPME device consists of fiber holder and fiber assembly with built-in fiber inside the needle which looks like a modified syringe (Fig. 1). The fiber holder consists of a spring-loaded plunger, a stainless-steel barrel and an adjustable depth gauge with needle, and is designed to be used with reusable and replaceable fiber assemblies An automated SPME system (CombiPAL, LEAP Technologies) was used with a 75 μm CAR/PDMS fiber assembly. The CAR/PDMS fiber is recommended for gases and low molecular weight compounds (MW 30-225). When new SPME fibers were installed they were conditioned in the gas chromatograph (GC) injection port at 300 °C for 2 h, according to the manufacturer's recommendations SPME uses a very simple apparatus similar to a modified syringe, and the device comprises a fiber holder and a fiber assembly that contains a 1- to 2-cm-long retractable SPME fiber (Vas & Vékey, 2004).

Simply program the temperature controller to the re-conditioning temperature specified by the manufacturer, insert the SPME fiber assembly into the. This research is important to study the applicability of the recent 60 µm PEG SPME fiber assembly for water samples containing both polar and less polar analytes. The aim of the present work was to study the applicability of the SPME method in combination with GC-MS for the simultaneous analysis of two triazine herbicides in water (atrazine and terbuthylazine), one chloroacetamide herbicide. The standard SPME fiber assemblies from Supelco are now complemented by a new configuration of SPME fiber assemblies called the fast-fit fiber assemblies or FFA for short. These SPME fibers are easy to install with no threaded attachment necessary for the fiber holder. In addition, the SPME fast-fit assemblies have a traceable label with a barcode. The advantage of the new SPME fast-fit assembly is there is no threaded hub as with the previous SPME fiber assemblies. So, it doesn't require.
