A method of determining a peak intensity in an optical spectrum is described. The method includes producing a two-dimensional array of spectrum values by imaging the optical spectrum onto a detector array. An offset using an actual location and an expected location of a peak of an interpolated subarray is used to adjust an expected location of another peak that is within another two-dimensional subarray. Interpolated spectrum values are then used to produce a peak intensity value of the second peak.

A flexible, foldable light-weight gas chromatography transfer line suitable for connecting a gas chromatograph (GC) to a spectrometer, such as a mass spectrometer or optical spectrometer, in particular to the ion source of the spectrometer, such as an inductively coupled plasma (ICP) ion source. The transfer line has a heating arrangement that allows maintaining an even temperature profile, which improves quality of spectra. The transfer line has low thermal mass and the heating can be controlled with the control unit of the GC.

An elemental analysis system includes a reactor having at least one reduction reaction zone including a metal zeolite that can reduce nitrogen oxides (NO) to molecular nitrogen (N) by selective catalytic reduction. Correspondingly, a method of elemental analysis includes providing a reactor having at least one reduction reaction zone including a metal zeolite and reducing nitrogen oxides (NO) to molecular nitrogen (N) by selective catalytic reaction on the metal zeolite.
