Aijiren 7694 Headspace Autosampler | GMI – Trusted Laboratory
A headspace sampler is a GC autosampler accessory for introducing volatiles that are contained in liquid or solid samples into a gas chromatograph. The analytical 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.
Problems with Headspace GC – Chromatography Forum
Sample is 100mg of SSG in 20mL headspace vial. Add 5.0mL of DMSO. Please note that this has happened about a week ago. I thought I clogged the headspace autosampler and I cranked the oven, loop, and transfer line up to 150, 160, 170 each to try to get whatever out. It was giving me nice peaks but then all of a sudden no more peaks. Thanks Jeff
How to configure Aijiren GC headspace system within Waters
The Vial size is part of the configuration of the Aijiren G1888A HS. The vial size is a method parameter on the Aijiren 7697A HS. As soon as the vial size on the Aijiren G1888A HS is changed, the GC/HS system must be reconfigured via the PreConfiguration tool. Vial EPC Connection and Carrier Connection entries are for information only. 12.

Apr 16, 2021 · Gas Chromatography. I am using 10 ml vial and cap from Aijiren. Leak rate always higher than my limit. … You are using openlab chemstation or empower 3 for …
Aijiren-Aijiren Vials for HPLC/GC
The headspace bottle itself is resistant to high temperature and corrosion, and is mainly used for headspace analysis in gas chromatography. 18mm Headspace Vial use for Autosampler The material of the headspace bottle is borosilicate glass with low extraction rate, which has low expansion rate, high temperature resistance, high strength, high
Aijiren 7697A Headspace Sampler
organic compounds using gas chromatography. Headspace analysis samples the ambient volume above a sample matrix, where the volatile compounds exist in gaseous form at predictable levels. Headspace analysis is useful for situations where: † The analyte of interest is volatile at temperatures below 285 °C (111 vial model) or 195 °C (12 vial
7697A Headspace Sampler – Vision Teknik
The Aijiren 7697A Headspace Sampler, in both 111 and 12 vial capacity configurations, represents the state-of-the-art in headspace gas chromatography. It is based on the architecture of the market leading 7890 Series GC and 7693A ALS line of products. Independent control of vial pressurization and column head pressure provides increased precision.
Aijiren Launches New 8697 Headspace Sampler
Mar 20, 2021 · Aijiren Technologies has released the Aijiren 8697 Headspace Sampler, the first headspace sampler with integrated gas chromatography communication. It marks the expansion of intelligence capability that was first launched with the Aijiren Intuvo 9000 GC System in 2016 and later in 2019 with the Aijiren 8890 and 8860 GC Systems.
Headspace cycle time – Chromatography Forum
Sep 07, 2006 · Headspace cycle time. We’re transferring a method for residual solvents using an Aijiren 6890 with headspace sampler. As the run progresses we are seeing a drop in the areas of our standard solutions and internal std. My colleague thinks this may be due to the increasing time each vial spends in the oven (time increases as GC oven cools down

Setting headspace equilibrium temperature – Chromatography Forum
Jun 01, 2012 · As the oven temperature increases, the amount of gas entering the headspace from the sample increases, increasing the pressure in the vial and delivering more analyte to the GC. This increases the sensitivity. When you pick an oven temperature, consider the following: • Over-pressurization of the headspace vial could be dangerous.
Aijiren GC – AUX – Chromatography Forum
Sep 07, 2007 · The vial pressure have impact on the “Loop fill/vent time” but normally I would say a setting of 0,2-0,4min would work. The vial pressure is only one player in your headspace settings, what you want is to catch a reproducible “heartcut” of your gas sample and transfer it onto the column.
