spectrometric การใช้

• Or a spectrometric trace of VX nerve agent or other chemical weapon?
• Costing, the HGSS can conduct magnetic, spectrometric and gravity surveys.
• Modern spectroscopic and spectrometric techniques have since superseded these techniques.
• OpenChrom supports only the analysis and representation of chromatographic and mass spectrometric data.
• Modern spectroscopic and spectrometric techniques have made this technique obsolete for all but pedagogical purposes.
• The structure was confirmed by mutagenesis and has an NMR and mass spectrometric detection ( MS3D ).
• He said that more than 1, 700 scientific papers using his mass spectrometric method had been published.
• Furthermore, the removal of CBB does not affect the yield of peptides in the mass spectrometric measurement.
• Bulk analysis assumes that the sample is fairly homogeneous and averages the emission or mass spectrometric signal over time.
• These samples had a for the first time reached Homogenitaet, which it made possible to accomplish spectrometric measurements.
• Electron-capture dissociation ( ECD ) was developed in 1998 to fragment large proteins for mass spectrometric analysis.
• Some drug testing laboratories have moved toward using the more specific mass spectrometric techniques as their primary screening and testing technique.
• Pogson also made special expeditions, observing a total solar eclipse on 18 August 1868 at Masulipatnam and making spectrometric studies.
• It is inert : as is the case with its lighter analogue, helium, no strongly bound neutral mass spectrometric studies.
• It is disposable and will be eliminated once complete the spectrometric experiment to prevent risk from reusing cuvettes and damaging expensive quartz.
• In particular many of the basic spectroscopic and spectrometric techniques were discovered in the early 20th century and refined in the late 20th century.
• However, experiments about the duration of the digestion process showed that after 3 h there is enough material for successful mass spectrometric analysis.
• An effort to develop a new method might involve the use of a tunable laser to increase the specificity and sensitivity of a spectrometric method.
• Analytical techniques for gas samples comprise gas chromatography with thermal conductivity detection ( TCD ), isotopic composition is usually determined by different mass spectrometric methods.
• But the investigators used mass-spectrometric techniques that permitted them to sort out isotopic lead composition at lead levels of only about one part per trillion.
