1 Circumvesuviana trains also go to Pompeii, Herculaneum, and Mount Vesuvius. 2  For Pompeii, get off at Pompeii Scavi stop, 36 minutes from Naples. 3  Trains for Herculaneum (Ercalano) and Mount Vesuvius depart several times an hour (don't take the Sorrento line).
Interest in Elemental Speciation Analysis â¢ Speciation analysis is the analytical activity of identifying and/or measuring the quantities of one or more individual chemical species in a sample. â The chemical species are specific forms of an element defined as to isotopic composition, electronic or oxidation state, and/or complex or molecular structure. â¢ Different forms of an element can have totally different properties. â Essential for predicting and modeling fate, risk, and effects, Critical for toxicology,
Different metal species have different health and safety or environmental impacts and so an accurate assessment is vital for client decision making processes. Metals Speciation Testing: 1  Sulphur species in hydrocarbon products. 2  Lead speciation in gasoline. 3  Arsenic Species As3+ and As5+ in water samples.4  Organometallic species analysis and identification. 5  Mercury Speciation in crude oil, refinery products, and other feedstocks.etals Speciation Testing: 1  Sulphur species in hydrocarbon products. 2  Lead speciation in gasoline. 3  Arsenic Species As3+ and As5+ in water samples. 4  Organometallic species analysis and identification.
