Low-volume sampling can be achieved by using a 6 mL vial and vial adapter. All PerkinElmer headspace vials are manufactured to specific tolerances that are guaranteed for fit and performance. Note: Due to the patent which PerkinElmer holds on the closures system of the Headspace vials, the caps, septa, and star springs cannot be sold separately.

competitive product analysis, source verification, and brand protection. There are several methods of headspace sampling commonly used for Gas Chromatography/Mass Spectrometry (GC/MS). This study compares automated liquid injection with headspace syringe injection and Solid Phase Microextraction (SPME) headspace for the analysis of several foods.

The steps of thermal desorption of the analytes and transfer into the gas phase for the gas-chromatographic separation are connected and thus analyte loss is avoided or at least minimized. The temperatures of the Inlet depend on the respective temperature during the chromatographic separation, but usually are between 100 and 300 ° C. The absorbed analyte molecules can also be dissolved from the fiber with the aid of a solvent. This method is used if later analysis is to be carried out by

Jul 25, 2022 · The GCMS-QP2010 SE is a single quadrupole gas chromatograph-mass spectrometer offering stable and cost-effective analysis for challenging compounds. A high-performance quadrupole mass filter ensures high sensitivity in both quantitative and qualitative analysis. The GCSMS-QP2010 SE is compatible with multiple sample introduction methods to enable a greater range of applications.

Solid phase microextraction (SPME) is an innovative and sensitive solvent-free sample preparation technology. Based on the principle of adsorption/absorption and desorption, SPME uses a coated fiber to concentrate volatile and semi-volatile compounds from a sample. SPME is widely used for a variety of applications involving environmental

Oct 26, 2021 · Solid Phase Micro-Extraction (SPME) is a simple adsorption/desorption technique that uses a fibre coated in an adsorbent material to extract analytes from liquid matrices or headspace gas. The sample is pierced by the needle and the SPME fibre is then exposed to the sample which allows analytes to adsorb to it. (Figure 2 from Chromacademy)

Sep 16, 2022 · The Next Industry Standard. In today's environment, results are needed regardless of whether the analyst is working in the laboratory, the office, or from home. With the flexibility to accommodate a variety of applications, the Nexis™ GC-2030 supports the analyst’s procedures beyond the laboratory, at virtually any location.

Solid Phase MicroExtraction (SPME) offers an approach that provides the benefits of these methods while at the same time eliminates the use of solvents and reduces analysis costs and the time required for sample preparation. Essentially all sample matrices, whether liquid, solid or gaseous, can be sampled by SPME.

coating material in chromatography. There are two typical SPME applications, sampling gases (headspace (HS)) or sampling solutions. In either case the SPME needle is inserted into the appropriate position (e.g. through a septum into the headspace), the needle protecting the fibre is retracted and the fibre is exposed to the environ-ment.

use of the DVB/carbon WR/PDMS SPME phase was chosen due to its selective extraction of odor and flavor compounds.
