Samples are usually analyzed as organic solutions consequently materials of interest (e.g.soils, sediments, tissues etc.) need to be solvent extracted and the extract subjected to various 'wet chemical' techniques before GC/MS analysis is possible.Beta Analytic uses Accelerator Mass Spectrometry (AMS) technology, which gives the most advanced precision and accuracy for Carbon-14 measurements.The lab is based in Miami, Florida, and is the world leader in Carbon-14 analyses since 1979.American physical chemist Willard Libby led a team of scientists in the post World War II era to develop a method that measures radiocarbon activity.

An important factor in decision-making is how quickly the results are reported, particularly if there are deadlines to meet.

In order for a compound to be analysed by GC/MS it must be sufficiently volatile and thermally stable.

In addition, functionalised compounds may require chemical modification (derivatization), prior to analysis, to eliminate undesirable adsorption effects that would otherwise affect the quality of the data obtained.

Gas chromatography mass spectrometry (GC/MS) is an instrumental technique, comprising a gas chromatograph (GC) coupled to a mass spectrometer (MS), by which complex mixtures of chemicals may be separated, identfied and quantified.

This makes it ideal for the analysis of the hundreds of relatively low molecular weight compounds found in environmental materials.
