The side hole needle is a specially processed needle with its inlet and outlet on the side of the needle, and the needle is sealed. It is specially used for gas chromatography gas injection, does not block the needle, does not damage the headspace inlet gasket, nor does it Damage to the gas chromatograph inlet seal to extend seal life and increase analysis success rate.
Operation method application example VWR HPLC vials china manufacturer
Determination of residual solvent ethyl acetate and chloroform in tea polyphenols
For gas chromatography analysis, for the analysis of samples of liquid, solid or liquid-solid mixtures, volatile components with a certain partial pressure of steam at normal or elevated temperatures, residual solvents in edible vegetable oils (GB5009, 37-85), polychlorinated Vinyl chloride monomer and its molded products (GB4615-84, GB5009, 67-85), organic pollutants in water such as benzene series, alkanes, alcohols, esters and volatile chlorinated hydrocarbons (GB5750-85), grain Analysis of odors and volatile organic compounds in pesticide fumigants, fruits, beverages, vegetables, cosmetics, soil, crops, packaging materials, and analysis of volatile organic compounds in various samples. This device can be used for analysis and testing. Standard preparation and injection
Headspace sampler In a 50 ml headspace vial, 25 ml of distilled water was added, the lid was capped, and the required amount of ethyl acetate and chloroform were separately injected using a 1 ul microinjector. Then, the headspace bottle was placed in a constant temperature water solution at 80 ° C for 1.5 h, and a head gas bottle space gas sample was taken out with a 1 ml gas injector to be injected into the chromatograph vaporization chamber VWR HPLC vials china manufacturer.
This is the end of the introduction of Headspace sampler set. I hope it can help you.
