How can the Kf value of a solvent can be determined?
In our chemistry lab we determined the Kf values using spectrometers.
What are some common uses of curium?
Curium is very scarce and expensive; today curium has only limited applications: - isotopes 242Cm and 244Cm are used as alpha particles sources for ?-spectrometers mounted on spacecraft engines to analyze planetary or cosmic samples. - precursor in the preparation of 238Pu and of isotopes of Sg, Hs, Cf, etc. In the past some other uses were proposed.
Difference between nmr and esr?
3. Differences between NMR and ESR1)Resonant FrequencyOne important difference between NMR and ESR is that in ESR the resonant frequencies tend tobe much higher, by virtue of the 659-times higher gyromagnetic ratio of an unpaired electronrelative to a proton. For example, a typical magnetic field strength used in ESR spectrometers is0.35 T, with a corresponding resonant frequency of about 9.8 GHz. This frequency range isknown as "X-band", and the spectrometer as an "X-band ESR spectrometer". Such spectrometersare readily available "off the shelf" from a (small) number of commercial sources.X-band ESR spectrometers are typically used to study small solid samples, or non-aqueoussolutions up to a few hundred μL in volume. They cannot be used for biological samples, or forin vivo studies, because of the strong non-resonant absorption of microwaves at 9.8 GHz. Forthat reason, ESR spectrometers (and imagers) have been constructed to operate at lowermagnetic fields, and correspondingly lower frequencies, including at "L-band" (about 40 mT and1 GHz) to study mice and "radiofrequency" (about 10 mT and 300 MHz) to study rats.2) Relaxation TimesThe second important difference between NMR and ESR is the typical relaxation timesencountered. In bio-medical proton NMR the relaxation times T1 and T2 are typically of the orderof 0.1 to 1 sec. In bio-medical ESR the equivalent electron relaxation times are a million timesshorter, i.e. 0.1 to 1 μsec! The extremely short relaxation times have important implications onthe way in which ESR measurements are carried out.
How are power work and time related?
power is required to do work and work efficiancy is the ammount of time it takes to do work.
Why does energy have the ability to do work?
Energy does not have the ability to do work, but we use energy to do work. Work is the application of force over a distance. The amount of energy changes how much work can be done, but energy technically does not do any work.
What are types of spectrometers?
no
Where can Raman spectrometers be bought?
Raman spectrometers may be purchased from numerous corporations that manufacture laboratory and analytic devices. Many, such as HORIBA and the Bruker Corporation, may be found via web searches.
How can the Kf value of a solvent can be determined?
In our chemistry lab we determined the Kf values using spectrometers.
Basic feature of different spectrometers?
Instrument which measures d ability of sample to absorb or transmit radiations
What is the chemical used to detect gas leakage?
Helium is generally used; special spectrometers to detect helium leakage are designed.
How can you use a spectrometer to detect black holes?
You can't use spectrometers to detect black holes. Telescopes are the only way to detect them.
What has the author M J Gallagher written?
M. J. Gallagher has written: 'Portable x-ray spectrometers for rapid ore analysis'
What are examples of scientific instruments?
Examples of scientific instruments include microscopes, spectrophotometers, telescopes, mass spectrometers, and DNA sequencers.
What is analytical instrumentation?
Analytical instrumentation: a large class of instruments used to analyze materials and to establish the composition. Some examples: spectrophotometers, mass spectrometers, gas chromatographs, potentiometric titrators, ion analyzers, polarographs, coulometers, x-ray spectro-meters, Karl Fischer titrators, atomic absorption spectrometers, fluorimeters and many, many others.
What has the author M R Carruth written?
M. R. Carruth has written: 'Reexamination of radiofrequency mass spectrometers' -- subject(s): Mass spectrometry
When was microwave spectrometer invented?
The microwave spectrometer was invented in 1947 by E. B. Wilson and R. H. Hughes. There are 2 types of microwave spectrometers.
What were the main products of the Laboratory Analytical Instruments industry?
Major product groups included clinical laboratory, chromatographic, and spectrophotometric instruments, and mass spectrometers.
