Magnesium image

The magnesium image showed many small spots that may, or may not, have been Mg-rich. Based on the label information, magnesium was known to be present in the sample however, if this had been an unknown sample then the image would have been of insufficient quality to determine the presence of magnesium. [Pg.399]

Because of its extreme insolubiUty, barium sulfate is not toxic the usual antidote for poisonous barium compounds is to convert them to barium sulfate by administering sodium or magnesium sulfate. In medicine, barium sulfate is widely used as an x-ray contrast medium (see Imaging TECHNOLOGY X-RAY technology). It is also used in photographic papers, filler for plastics, and in concrete as a radiation shield. Commercially, barium sulfate is sold both as natural barite ore and as a precipitated product. Blanc fixe is also used in making white sidewall mbber tires or in other mbber appHcations. [Pg.482]

Salt glands of plants from Atriplex genus contain inclusions in the form of crystals of siliceous or sulphate salts of calcium and magnesium (Fahn, 1979). Usually the crystal particles also include phenols (see Chapter 7). The crystals are seen as dark dense spots within the structures on OCM images of the optical slices from the gland (Fig. 4). Profiles of signal intensity along... [Pg.111]

Bioluminescent reactions are also employed for imaging purposes, in particular the firefly and the bacterial luciferin/luciferase ones (Fig. 1). The firefly luciferin/luciferase reaction requires ATP, magnesium ions, and oxygen. Many different luciferins and mutant luciferases have been investigated to optimize the... [Pg.480]

Of all of the machines used for microanalysis LAMMA seems to be the most problematic. A laser beam is used to disintegrate a spot in the sample, and the material emitted is then analyzed in a mass spectrometer. It has similar lateral resolution to PIXE, and like SIMS can be used to distinguish between isotopes of the same element. It has, however, proved very difficult to quantify, and is destructive to the specimen. One recent investigation (13) ofthe distribution of stable isotopes of calcium, magnesium, and potassium in Norway spruce used three microprobes EDAX at 0.3 pm lateral resolution isotope specific point analysis, using LAMMA at 1.5 pm lateral resolution and isotope specific imaging using SIMS at 1-3 pm lateral resolution. [Pg.278]

Also depicted on the graph in Figure 8.5 is the number of moles of magnesium sulphate produced. It should be apparent that the two concentration profiles (for reactant and product) are symmetrical, with one being the mirror image of the other. This symmetry is a by-product of the reaction stoichiometry, with 1 mol of sulphuric acid forming 1 mol of magnesium sulphate product. [Pg.365]

An important factor of film quality concerns its adhesion to the substrate, namely to the magnesium chip. Figure 4.12 shows images of different coated chips after a standard adhesion test. The upper images show the magnesium-coated chips after the tape was peeled off, while the lower images show the tapes. [Pg.93]

Figure 4.12 Optical images of coated magnesium chips and their corresponding tapes after an adhesion test (A) PTMOS film (B) ZrTPO film (C) combined film. The images of the tapes are somewhat misleading as the coloured area of the combined film is the largest, which is due to its high content of Rhodamine B. (Reproduced from ref. 13, with permission.)...

Comparison of Reproduceability of Isolated Image Lines between the Photopolymer Plate and Powderless Etched Zinc or Magnesium Plate. [Pg.275]

As shown in Fig. 17, the Photopolymer Plate will reproduce the isolated image lines almost completely from the negative film. Contrary to the Photopolymer Plate, zinc plate or magnesium plate gives much less reproduceability of only 76-65%. [Pg.275]

Methodology Six samples were analyzed three passed the dissolution test (good samples) and three failed (bad samples). Several ingredients were used as references Avicel (cellulose), the API, magnesium stearate, and poloxamer. Dissolution was tested after NIR imaging measurement to obtain the wet chemical references. [Pg.425]
