Spectrometer
Spectrometer is polychromatic light is separated into optical spectroscopy. There are many types of spectroscopy, in addition to the spectrometer of visible light band used, and infrared spectrometer and UV spectrometer. According to the dispersion can be divided into different components of a prism, grating spectrometer and spectrometer. According to the detection method, a direct observation of ocular spectroscope, using film to record the spectrograph, and the use of photoelectric and thermoelectric element detection spectrum spectrophotometer.

According to the detection method, a direct observation of ocular spectroscope, using film to record the spectrograph, and the use of photoelectric and thermoelectric element detection spectrum spectrophotometer. The monochromator slit spectrometer is the only output monochromatic spectral line, often used in conjunction with other analytical instruments.
Spectrometer is the complex light decomposition of spectral lines of scientific instrument, composed of a prism or grating spectrometer, the reflective surface of the measured object light. The sun seven color is the naked eye can divided into parts (visible light), but if the spectrometer to decompose sunshine, according to the wavelength of visible light are arranged, only the scope is very small in the spectrum, the rest are unable to distinguish between the naked eye spectrum, such as infrared, microwave, ultraviolet ray, X etc.. The spectrometer, optical information to crawl on photographic film developing, or computerized automatic display numerical display and analysis, to measure the knowledge items containing what elements. This technique is widely applied to the detection of air pollution, water pollution, food hygiene, metal industry in.
Working principle:
According to the working principle of the modern spectrum instrument, spectrometer can be divided into two categories: classical spectrometer and spectrometer. The classical spectral instrument is a new instrument based on the principle of spatial dispersion; model spectral instruments were built on the modulation principle. The classical spectral instruments are slit spectrometer. Modulation spectrometer is divided into light non space it adopts the round hole, into the light
According to the optical principles of dispersion component, spectral instruments can be divided into: prism spectrometer, diffraction grating spectrometer and the spectrometer optical multichannel analyzer. OMA (Optical Multi-channel Analyzer) is the use of photon detector in recent years (CCD) and computer control model spectrum analysis instrument, it sets the information acquisition, processing, storage functions in one. Because the OMA is no longer used photographic emulsion, avoid and save a series of complex processing, darkroom processing and measurements, the conventional spectrum technology has fundamentally changed, greatly improving the working conditions, improve work efficiency; spectral analysis using OMA, accurately and rapidly, conveniently, and has the advantages of high sensitivity, fast response time, high spectral resolution, measurement results can be immediately from the screen read or by the printer, plotter output. At present, it has been widely used in the spectrum measurement of almost all of the work, analysis and study, especially suitable for weak signal, detection of transient signals.
Method of use:
Start
1.1 if the stop in 2-8 hours, then cold water to run for 10 minutes, the cold water in the first 5 minutes of running; such as shutdown in 8 hours, then water is required to run for 15 minutes, the cold water in the first 10 minutes of running.
1.2 boot sequence for open water
1.3 open water (COOLER) switch
1.4 open CTROL, VACUUM switch (observed in vacuum degree is reduced to below 10, the conductivity observed in cooling water is below 10)
1.5 open HEATER
1.6 open the board of high-voltage switch
1.7 open the computer, open the MXF operating software, click Monitor, and check whether the online observation
1.8 all normal, open the panel right below the X-RAY switch
1.9 click the X-RAY ON button at the top left panel, open X X-ray on (5KV-0mA) - (10KV-mA) - (15KV-0mA) - (20KV-0mA) - (20KV-5mA) - (20KV-10mA) in order to increase flow, pipe pressure. Such as downtime in 2-8 hours, then each need to wait for 10 minutes; such as shutdown in 8 hours, then each need to wait for 20 minutes
1.10 click the Maintenance column - pop Maintenance-MXF- click Inrument Setup- pop Instrument Setup- below the X-ray pipe pressure, Guan Liu field, the two set (30, 20), click on the implementation, can restore the standby state light tube, for routine analysis.
