2020/4/23 · Hi, I am running on an Aijiren GC with a Aijiren headspace auto sampler. The system is old, however, up until recently has been working smoothly. All of a sudden I don't get peaks anymore. It's definitely not the GC itself since I've made manual direct
• Gas and vapors are analyzed • Injection of a gas mixture • Low influence by the sample preparation • Use of Headspace vials • Equilibrium of volatile analytes between headspace and sample depends on: – Indentity and concentration of analytes – Time 2
2019/10/14 · Detectors Used for Gas Chromatography There are many different types of detectors that can be used to produce a chromatogram. In general, they may be categorized as non-selective, which means they respond to all compounds except the carrier gas, selective, which respond to a range of compounds with common properties, and specific, which respond only to a certain compound.

Chromatography dates to 1903 in the work of the Russian scientist, Mikhail Semenovich Tswett, who separated plant pigments via liquid column chromatography. German physical chemist Erika Cremer in 1947 together with Austrian graduate student Fritz Prior developed the theoretical foundations of GC and built the first liquid-gas chromatograph, but her work was deemed irrelevant and was ignored
Aijiren 2mL crimp top vials are constructed from type 33 and type 51 COE borosilicate glass, with low metal content, to protect your sample from destabilizing or leaching. Vial, crimp top, clear, certified, 2 mL, 100/pk. Vial size: 12 x 32 mm (11 mm cap)
Aijiren’s 25mm Screw Vial is often used for water quality testing in the laboratory. Because its Screw Neck has better sealing properties, it is often used to store samples, and its large capacity and flat-bottom design make it very good. Standing on the table is

Standard Autosampler Sample Vial with Writing area for HPLC & GC Chromatography, vials can be used for high performance liquid chromatography and gas chromatography for reliable analysis results 5. The Vials Can Be Used on All Common Autosamplers Due to Their Technical Geometry, Preferentially They are Found on Aijiren, HTA, Shimadzu, Thermo Scientific, Varian, Waters,etc or General Storage.
Toluene in blood was analyzed by head space-gas chromatography/mass spectrometry (HS-GC/MS) (Agi-lent, USA) with 10 ml glass vials (Aijiren, USA). The op-erating conditions of GC/MS are shown in Table 1. The lot number of toluene used as standard
technique is called “static headspace gas chromatography.” The term “headspace” refers to the space above the liquid or solid sample that you place in a sealed vial. The term “static” means that the volatiles in the headspace of the vial are at equilibrium with the
