When it comes to flexibility, ease of use and sensitivity, one family of gas chromatography (GC) systems stands apart: Clarus. Our family of GC instruments delivers the performance you need, day after day, and is compatible with virtually all sample introduction systems, including our world-class TurboMatrix, Headspace, and Thermal Desorption.

Special pre-cut septa (silicone layer is slitted but PTFE remains intact) for safe penetration of the sensitive SPME phase with hardly any coring Tested and approved by CTC for their Combi PAL (Gerstel, Atas, Aijiren), also recommended by Aijiren for their A samplers, by Shimadzu for AOC5000 and for PerkinElmer TurboMatrix autosamplers

Shimadzu sells many types of vials and septa. 1st hydrolytic class and silanized glass vials. Screw vials, micro-vials, caps and sept, screw vial kits and headspace vials and much more.

Headspace solid-phase microextraction (HS-SPME) coupled with gas chromatography-mass spectrometry (GC-MS) was used to analyse microbial volatile organic compounds (MVOCs) of mushroom disease-related microorganisms.

10ml and 20ml Crimp Top Headspace Vials These clear glass headspace vials used for gas chromatography available in 10ml and 20ml with 20mm open top aluminum crimp cap (10mm hole) pre-inserted with 20mm PTFE-Silicone septa in different combinations.

GC headspace vials, caps and a number of septa options so you can select that most suited for your application. Our patented vial and cap design incorporates pressure-relief features which guarantee safe operation with the high pressure typically developed during thermostatting.

Static headspace-gas chromatography (HS-GC) is an indispensable technique for analyzing volatile organic compounds, enabling the analyst to assay a variety of sample matrices while avoiding the

Jan 02, 2006 · One possibility of silicone septa contamination relates to diffusion through the headspace, as characterized in Figure 3b and c, where the septum was punctured once by the 10-μL syringe needle with a 250-μL aliquot of hexane sealed in the vial. With the sensitivity of the method herein, no contamination was detected 8 hr after puncturing, and

Vials Cap Septa for GC HPLC Our product range includes a wide range of hplc solvent inlet filter, inlet filters, debubbler, 2ml amber sample screw vials, 250ul conical micro-insert, vial micro-insert and 1.5ml clear screw neck vial w/write-on spot.

72 N6352031 Septa, Tefon/Silicone, 22 mm, 0.125 mil Thick 72 N6352032 Open Top Closure, Polypropylene. 24-414 Thread Cap 24 N6352033 CHOOSING THE RIGHT SEPTA FOR YOUR ANALYSIS Although a wide variety of septa is available, chemical compatibility and temperature are the most critical to the analysis.

PTFE/White Silicone Septa. Excellent choice for general volatiles analysis. Septa are packed in a glass PurePak jar to assure low background, low permeability, and the highest performance of any headspace septum. PTFE/Silicone septa provide excellent resealing characteristics and broad chemical compatibility.

When separating organic and inorganic compounds for analysis, chromatography vial closures protect compound mixtures from contamination. The caps feature different finishes and septa materials for gas or high performance liquid chromatography applications. Maintain a clean and safe workplace using the spill-free chromatography vial closures available in various sizes and styles to be

Often bits of septa get stuck inside the transfer line needle. This is usually caused by puncturing the septa, with the strain relief nut tightened too much. This hardens the rubber, and the needle cores pieces away. Your GC and headspace should have the same supply pressure. Usually about 80 psi. See more results
