“…The experimental set-up has been described in detail elsewhere. [17][18][19] Briefly, vacuum ultraviolet (VUV) photons from the DISCO beamline at the SOLEIL synchrotron radiation facility (Gif-sur-Yvette, France) were monochromatized and guided to the APPI source exactly where the photons are emitted by the discharge lamp of the commercial Photospray TM source (AB Sciex, Toronto, Canada). The source is coupled to a hybrid quadrupole-time-of-flight mass spectrometer (Q-Star Pulsar i, AB Sciex).…”

“…16 We recently described a new set-up allowing the acquisition of atmospheric pressure photoionization (APPI) mass spectra at various photon energies using a tunable ultraviolet (UV) source at the SOLEIL synchrotron radiation facility. [17][18][19] We employed this unique experimental device to determine the IEs of ten isobaric monoterpenes with a dramatically reduced sample consumption.…”

Monoterpenes are the main class of biogenic volatile organic compounds. They promptly react with oxygen and nitrogen species, leading to the formation of secondary aerosols. The determination of their physicochemical properties, such as their ionization energies (IEs), is crucial to understand better their reactivity. We previously introduced a modified atmospheric pressure photoionization source coupled to a tunable vacuum ultraviolet source at the SOLEIL synchrotron radiation facility. Here, this set-up is employed to determine IEs of ten monoterpenes with a good precision (±50 meV) and a small sample consumption limited to 10 μg.

The Liquid Chromatography-Mass Spectrometry (LC-MS) is a powerful analytical technique with very high sensitivity and specificity. LC-MS is combination of Liquid Chromatography (LC) and Mass Spectrometry (MS). With the Liquid Chromatography (LC) the separation of components can be done and then the sample eluents from LC are transferred into Mass Spectrometry (MS) where the detection, identification and determination of masses of components can be done in presence of other components. LC-MS is used in determination, of pharmaceutical drug substances, intermediates and its related compounds for quantitative and qualitative purpose. LC-MS is used most significantly in in-vitro dissolution, bio-equivalence, bioavailability and metabolite studies. Also LC-MS is used in basic research, agrochemical, forensic laboratories and food industries .In this article principle of LC-MS, instrumentation and its applications are briefly discussed.

“…Recently, we published a study using a PhotoSpray TM APPI source fitted on a commercial hybrid quadrupole-time-of-flight mass spectrometer and coupled to a tunable UV source at the SOLEIL synchrotron radiation facility, to elucidate the ionization mechanism of guanine under dopant-assisted APPI conditions [16]. By scanning the photon energy below and above the ionization energy of the dopant, it was possible to describe the competitive chemical reactions which lead to the ionization of the model nucleobase.…”
