IRMS - ToF configuration

The system is designed around a central Gas Chromatograph (GC) oven into which a sample is injected (Figure 1).

Following chromatographic separation, a portion of the sample is split from the column effluent and carried to MS solutions ISOToF™ Time of Flight MS for compound identification.

The remainder of the sample is then passed through a combustion and / or reduction furnace. This converts the sample into analyte gas of choice (e.g. CO2, N2, H2 etc.). The analyte gas is then passed through a nafion™ membrane, to remove any water, and into MS solutions Isotop^e IRMS for isotopic identification.

MS solutions Mass Analyser Pro™ (MAPs), then permits seamless integration and interpretation of peaks acquired from both instruments.

	Continuous Flow (CF) isotope ratio analysis has traditionally focused on relatively simple matrices, often containing no more the one or two compounds. Although chromatographic retention times are adequate for identifying compounds in simple systems, complex environmental or biological samples pose a far greater challenge. For this reason MS Solutions has developed a system capable of simultaneous compound identification and isotopic characterisation.
