Products for SPME - Solid Phase Micro Extraction | analytics

SPME (Solid Phase Micro Extraction) is a procedure of sampling. Later the samples can be analyzed via GC or HPLC. Sampling. Samples which are to be analyzed by gas chromatography are usually filled in so-called autosampler vials, which are sealed with a crimp lid. For sampling, an SPME needle is pierced through the septum into the sample vial.

Effects of ripening degree and sample preparation on peach

A standard headspace vial (Supelco, 75 mm height × 23 mm opening) with a volume of 20 mL has some important drawbacks. For instance, with the increasing amount of the sample, the headspace above the sample is critically reduced, and consequently a homogeneous stirring is questionable. With the intention to solve this problem, we

SPME Technique for Analyzing Headspace Volatiles in Fish Miso

Optimization of the SPME technique. The fiber of the SPME device (Supelco, Bellefonte, PA, USA) was inserted into the headspace of a 22-ml glass vial with a polytetrafluoroethylene/silicone liner contain-ing the sample and sealed tightly with an aluminum cap (Supelco, Bellefonte, PA, USA) for sampling the volatiles. Ten different volatile

SPME Sampling Stand for use with 15 mL vials

Holds eight vials while supporting the SPME syringe for consistent fiber immersion depth. Cat. No. 57333-U accommodates 4 mL vials only; Cat. No. 57357-U accommodates 15 mL vials. Order the 15 mL vial puck (Cat. No. 57358-U) as a replacement for the 15 mL unit, or to use 15 mL vials with the 4 mL unit. Not for use with automated/HPLC fiber holders.

Optimization of Headspace Sampling Using Solid-Phase

Volatiles are important flavor compounds of fruit juices and beverages. In this study, a headspace Solid-phase microextraction (SPME) gas chromatography-mass spectrometry (GC-MS) was used to analyze the volatile components in starfruit juices.

Selection Guide for Supelco SPME Fibers - İNTERLAB Laboratuar

06.11.2015Selection Guide for Supelco SPME Fibers. In SPME, you can adsorb analytes from a liquid sample, by immersion or headspace extraction, or a solid sample, by headspace extraction, using a polymer-coated fused silica fiber. Analytes are desorbed from the fiber by exposing the fiber in the injection port of a GC or in the desorption

SPME for GC Analysis - Supelco

With the fiber retracted, pass the needle through the sample vial septum. Depress the plunger to expose the fiber to the liquid sample or the headspace above the sample. Analytes adsorb to the fiber in 2 to 30 minutes.

An Automated Headspace SPME-GC-ITMS Technique for Taste and

toluene-d8, was added to all samples. The vials were capped using a Crimpmaster (Wheaton Inc.) and the NaCl was dissolved by gently swirling the vials. The vials were placed into a 12-vial carousel on a Varian autosampler (8200 CX). The analysis was started by automated insertion of the SPME fibre into the vial headspace for 50 min of absorption.

A Novel Approach by SPME-GC/MS for the Determination of gamma

The sample vial was equilibrated at 80 °C for 5 min. For adsorption, the needle of the SPME device containing the extraction fiber (SPME fiber assembly polyacrylate df 85 μm, Supelco, Sigma Aldrich, Steinheim, Germany) was inserted through the septum of the vial and the fiber was exposed to the headspace in the vial for 5 min.

An Aijiren Guide to SPME Analysis

Solid Phase Microextraction (SPME) is a fast, solvent-less sample extraction technique. It is used for extracting organics from a matrix (solid, liquid, or gaseous) into or onto a stationary phase immobilized on a fiber. In SPME, analytes establish equilibria among the sample matrix, the headspace above the sample, and a polymer-coated fused fiber.
