Electrophoresis,nts may be molecular, for example, proteins, or cells or even charged particles, but here we shall restrict our discussion to charged molecules (ions). Similarly, the fluid medium may be liquid or gaseous, but in biological systems it is only electrophoresis in the former that is of interest.

Fluorescence and phosphorescence spectrophotometry,r in the nature of the ground and excited states. A molecule may be excited from a singlet ground state to a singlet excited state by the absorption of radiation in the UV or visible region of the spectrum. Electronic excitation is accompanied by excitation to a higher vibrational energy level. The 作者: 四目在模仿 時間: 2025-3-22 20:49
Infrared spectroscopy,rd spectrometers scan the mid-IR region between 4000 and 400 cm. (2·5–25 .m). The near-IR extends from 12 500–4000 cm . (0·8–2·5 .m), and the region from 400–50 cm . (25–200 .m) is known as the far-IR. IR radiation causes transitions between vibrational energy levels and also between rotational ener作者: 莊嚴 時間: 2025-3-22 22:37 作者: enterprise 時間: 2025-3-23 03:37
Electron spin resonance,cies containing unpaired electrons. Thus it is restricted to free radicals, paramagnetic metal ions and molecules in a triplet electronic state. The technique involves the absorption of microwave radiation, which induces transitions between electronic magnetic energy levels.作者: 圓木可阻礙 時間: 2025-3-23 07:04
Flame techniques,c species from inorganic analytes in solution. The simplest of these is flame photometry, now more commonly termed flame emission spectrometry (FES), which is based on the measurement of the light emitted when atoms raised to an excited state by the thermal energy of the flame return to the ground s作者: 有危險 時間: 2025-3-23 11:14 作者: Gossamer 時間: 2025-3-23 17:41
Electrochemical techniques, easily electricity passes through it. The situation becomes more complex when the geometry of the conductor is changed, for example into a coil, and alternating current is used. However, under direct-current conditions the current passing through a conductor is defined by Ohm’s law:.where .(in volt作者: drusen 時間: 2025-3-23 19:56

,UV—visible spectrophotometry,The visible region of the spectrum ranges from 400–700 nm, which corresponds to frequencies of 7 × 10.–4 × 10. Hz. Radiation at the low-energy high-wavelength end of the spectrum is perceived as red, while that at the high-energy part of the spectrum is blue. The spectral region between 180–400 nm corresponds to the ultraviolet (UV) region.作者: forbid 時間: 2025-3-25 19:17

Nuclear magnetic resonance spectroscopy,, when it plays a key role in structural analysis and identification of organic molecules. Although NMR is less sensitive than some techniques, such as UV or fluorescence spectrophotometry, it can be applied much more widely and provides specific structural information that is often adequate for the unambiguous identification of organic molecules.作者: 爵士樂 時間: 2025-3-26 14:29 作者: adj憂郁的 時間: 2025-3-26 18:14 作者: delta-waves 時間: 2025-3-27 00:51

Mass spectrometry, a fingerprint which is used for identification of the molecule. The mass spectrum consists of a series of peaks of varying intensity plotted against the mass-to-charge ratio (./z). Mass spectrometry combines high specificity with great sensitivity, since amounts of less than a picogram of some compounds can be detected.作者: 安定 時間: 2025-3-28 01:36
