2022/12/05 · The most prevalent means to analyze NAs in water is SPE coupled with gas chromatography-mass spectrometry (GC − MS) [2,[99], [100], [101], [102]]. The analysis of NAs such as NDMA in water has proven very challenging due to its high polarity and the low detection limits required, which are below the detection limits achievable with many instruments (low ppt

Headspace Analysis works on the principle of Tunable diode laser absorption spectroscopy (TDLAS), a non-destructive method able to measure the concentration of a certain gas in closed container even at very low detection limits, with a sufficient headspace size to pass through with a laser beam. The wavelength diode laser is tuned over the

Headspace GC is a sampling technique that involves the indirect determination of volatile constituents in liquid or solid samples by analysing the vapour phase that is in thermodynamic equilibrium with the sample in a closed system [ 149, 150 ]. It is used predominantly for the determination of volatile constituents present in trace concentrations.
