amber headspace gas chromatography Australia

A gas chromatograph (GC) is an analytical instrument that measures the content of various components in a sample. The analysis performed by a gas chromatograph is called gas chromatography. Principle of gas chromatography: The sample solution injected into

Headspace vials and closures (sold separately) must form a tight seal for accurate analysis with reproducible results. Available in clear or amber Type I borosilicate glass with crimp finishes. The vials are used to heat the sample until the concentration of the liquid and gas phases are in equilibrium.

1/6/2021 · The headspace gas chromatography (HS-GC-FID/FID) method for the determination of ethanol in beers, wines and soft drinks has been evaluated and fully validated. The described technique is sensitive and precise with a sufficiently wide range (0.01–20.0%), therefore it can be applied for quality control of beverages in accordance to both, EU standards and BJCP recommendation.

(7)Trajan Scientific and Medical, Victoria, Australia. A headspace gas chromatographic approach based on flame ionization detection has been successfully developed for the determination of parts-per-billion levels of 2,4-dichlorophenol and 2,6-dichlorophenol in processed dairy milk.

This is a completely integrated high throughput system with easy-connect bioreactors and flexible software that enables scientists to manage many more experiments at the same time while reducing the cost per experiment. The Ambr ® 250 is ideal for scaling down processes based on its fully featured bioreactor design and provides a step change improvement in lab productivity.

Formaldehyde is a highly reactive impurity that can be found in many pharmaceutical excipients. Trace levels of this impurity may affect drug product stability, safety, efficacy, and performance. A static headspace gas chromatographic method was developed and validated to determine formaldehyde in pharmaceutical excipients after an effective derivatization procedure using acidified ethanol
