Sample extracts were analyzed for pesticide content using mass spectrometric detection.
They took sludge samples gathered from around the country and measured the metal content using a mass spectrometer that can discern different elements as they are ionized in a superhot plasma.
In this study 265 honey samples of different botanical origin (polyfloral, citrus, rhododendron, eucalyptus, acacia, chestnut and honeydew) produced throughout Italy in different years were analysed to determine stable isotope ratios (SIRs) using Isotope Ratio Mass Spectrometry and mineral element content using Inductively Coupled Plasma Optical Emission Spectroscopy.
The tumor tissue was frozen and stored in cryogenic storage tubes before being analyzed for total platinum content using inductively coupled plasma mass spectrometry.
They measured the specimens' 14C content using a sensitive technique called accelerator mass spectrometry.
Samples were analysed for BB-3644 content using a validated reverse-phase HPLC method with mass spectrometric detection.
Following these reactions, samples were analyzed for metabolite content using an Agilent 7890 gas chromatograph system coupled with a Pegasus 4D time-of-flight mass spectrometer.
Then, the leaves were oven-dried for 48 h at 65 °C, for determining LMA (dry mass/area), the ratio of leaf water to dry mass (Wm), carbon content (C) using the Walkley Black wet oxidation method, N content by the micro-Kjeldahl method and P content using atomic absorption spectrum-photometry.
We then analyzed the acidified extracts for elemental content using inductively coupled plasma mass spectroscopy (ICP-MS) (McGee et al. 2003).
Thermogravimetric analysis (TGA) is used to determine the mass content of RGO in the Mn3O4/RGO composites.
