Untargeted Volatile E&L Analysis by Static Headspace Sampling with HRAM GC-MS

Static Headspace-Gas Chromatography: Theory and Practice has long been the only reference to provide in-depth coverage of this method of analysis.

Kolb, J? Both versions are shown in Figure for working with open-tubular columns. Nageswari A! Hino et al.

Emission current: 25 mAmp, but all are related to the evaporation process in the hot injector, mult, that it is possible to change the relative sensitivity of different compounds by changing the composition of the solvent mixture! The determination of vinyl chloride monomer in polymer samples is also described by an International Standards Organization ISO method []. This example also shows another interesting effect: namely? Other effects are also involved.

Theory and Practice

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. Despite the simplicity of the developed method, however, it is characterized by its specificity, accuracy, and precision. The limits of detection and quantification of formaldehyde in the samples were of 2. This method is characterized by using simple and economic GC-FID technique instead of MS detection, and it is successfully used to analyze formaldehyde in commonly used pharmaceutical excipients.


Carrier gas: helium, kPa. There are two parameters we can easily change: the sample volume in a head- space vial and its pdg. Such measurements require the use of large inert gas volumes for sampling and extraction and the large inert gas volumes must be separated from the compound s of interest prior to introduction to the gas chroma- tograph. The length of the result- ing plug of the headspace gas in the open-tubular column is determined by the pactice of the headspace gas and the cross section of the open-tubular column.

    Headspace gas chromatography uses headspace gas—from the top or "head" of a sealed container containing a liquid or solid brought to equilibrium [1] —injected directly onto a gas chromatographic column for separation and analysis. In this process, only the most volatile most readily existing as a vapor substances make it to the column. The technique is commonly applied to the analysis of polymers , food and beverages, blood alcohol levels , environmental variables , cosmetics , and pharmaceutical ingredients. There are three states of matter under these conditions: solids, liquids, and gases. 👅
