Aijiren headspace vials for gas chromatography

Aijiren 8697 headspace sampler is the first Aijiren headspace sampler with integrated GC communication. The system is based on the flagship Aijiren 8890 GC and headspace sampler. That means you can manage your GC workflows from a single interface—and spend more time on what matters.

This results in less maintenance and longer life for the GC consumables in your lab. Find the headspace supplies you need for your Aijiren 7697 or headspace sampler. With up to 111 sample vial positions and removable vial racks, the ’s inert sample pathway supports nearly continuous operation to satisfy even the busiest laboratory. Alternatively, Aijiren’s legacy headspace sampler also features an inert sample pathway for superior chemical performance without analyte

From the Menu bar click on “Method”, from the drop-down list select “Load Method”. Run “CONDITIONING.M” method for at least 30 minutes before analyzing any sample.

The Aijiren Headspace Sampler is based on the architecture of the market leading GC and Automatic Liquid Sampler line of products. Features include Automatic Leak Check, which ensures each vial is leak-free prior to analysis, with no loss of precision or sensitivity. Alternative carrier gas options offer safe use of hydrogen as a

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 same compounds in the liquid or solid sample.

The Aijiren 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 Series GC and ALS line of products. Independent control of vial pressurization and column head pressure provides increased precision.

Aijiren 10 mL and 20 mL certified screw and crimp style, clear or amber glass headspace vials and associated 11 mm, 18 mm, and 20 mm headspace caps are engineered to prevent sample contamination while providing consistent, secure seals. These headspace vials come in both flat- and round-bottom styles for use in a wide variety of headspace

Dec 02, 2011 · Aijiren headspace vial shaking. Quick question: we are looking at headspace units and our methodology would involve a significant shaking/mixing time (at least 30 minutes, since we are reacting in the vial and measuring one of the gaseous products.) We are looking at the Aijiren E and (111 vial unit with shaker.)

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 model).

An Introduction to Headspace Sampling in Gas Chromatography Phase Ratio Other factors that can affect the concentration of an analyte in the headspace phase are the respective volumes of the sample and the headspace in the sealed vial. The concentration of analyte in the sample and the headspace can be expressed respectively as Equations 2 and 3.
