18mm Headspace Vials & Closures - Aijiren Tech Scientific

Unlike crimp cap vials, Aijiren Tech National 18mm Screw Top Headspace Vials require no tools for closure. Manufactured with superior quality (Type 1, Class A) glass, they are available with a round bottom in sizes with usable volumes of 10mL or 20mL. The

Development of Heated Headspace Solid Phase Microextraction

separate 20 mL headspace vials sealed with magnetic caps for HHS -SPME-GC/MS. The fiber used for headspace sampling was a polydimethylsiloxane (PDMS) SPME fiber (23 gauge, 100 µm) obtained from Sigma -Aldrich (St. Louis, MO). It was installed onto

Quantitation of 2-acetyl-1-pyrroline in aseptic-packaged cooked

The present study demonstrates that a standard addition method, whereby up to 1,000 ng of 2AP standard is spiked into 4 g of APCR containing 5%-100% FR in a 20-mL headspace vial followed by SPME/GC-MS, may serve as an effective means of quantitating

L-PAL3 | GC Autosampler | LECO

L-PAL3 GC Autosampler For Liquid and SPME Injections. This CTC-based robot combines an autosampler and injector that operates in three dimensions of space. It provides everything needed to perform standard liquid injections and all SPME-type analyses (immersion, headspace). This package includes a heated agitator, 5-position solvent wash

Determination of synthetic polycyclic musks in water by microwave-assisted headspace solid-phase microextraction and gas chromatography-mass

The effects of various extraction parameters for the quantitative extraction of these analytes by MA-HS-SPME were systematically investigated and optimized. The analytes in a 20-mL water sample (in a 40-mL sample-vial containing 4 g of NaCl) were efficiently extracted by a polydimethylsiloxane-divinylbenzene (PDMS-DVB) fiber placed in the headspace when the system was microwave irradiated at

Determination of volatile organic compounds in water by headspace

In the optimized procedure, 4 mL of water sample were extracted using a 10 mL vial and adding 0.4 g NaCl (final NaCl content of 10%). An SPME extraction with carboxen/polydimethylsiloxane 75 μm fiber for 30 min at 50°C (with 5 min of previous equilibration time) with magnetic stirring was applied.

Automated headspace solid-phase microextraction and in-matrix

An automated extraction and determination method for the gas chromatography (GC)-mass spectrometry (MS) analysis of amphetamine-related drugs in human urine is developed using headspace solid-phase microextraction (SPME) and in-matrix derivatization. A urine sample (0.5 mL, potassium carbonate (5 M,

Vials & caps | Markes International

Markes supplies a range of vials and caps to support users undertaking headspace (HS), solid-phase micro-extraction (SPME), thin-film SPME (TF-SPME) and HiSorb sorptive extraction sampling. Vials are available in 1.5, 10 and 20 mL sizes, with crimp-tops or screw-tops. Caps to suit sampling method (s) are provided with the appropriate septum.

Aijiren Tech headspace vials are available in clear or amber glass with a round or flat base, a crimp seal with a beveled or square edge finish, or with a screw-thread finish. Headspace vials, septum, and caps can be purchased in various quantities separately or

"Simple and accurate quantification of BTEX in ambient air by SPME

1/7/2016 · To provide sufficient accuracy, the use of 20 mL vials requires triplicate sampling and analysis. The method was successfully applied for analysis of 108 ambient air samples from Almaty, Kazakhstan. Average concentrations of benzene, toluene, ethylbenzene and o-xylene were 53, 57, 11 and 14 µg m−3, respectively.
