通過光電轉換裝置將光譜儀轉化為光電流。所以所謂的光譜強度，使這種電流直
接測量稱為直接法，行業中領先的光譜儀可以測量瞬時值，如果我們充電這個電流到電容器裝置，經過一段時間后，測量電容器件的電壓大小是所謂積分法而得到的信號是平均充電時間。下面分享使用制冷型光纖光譜儀要注意的事情有哪些？
The spectrometer is converted into photocurrent by a photoelectric conversion device. So the so-called spectral intensity makes the direct measurement of this current called direct method. The leading spectrograph in the industry can measure the instantaneous value. If we charge this current to the capacitor device, after a period of time, measuring the voltage of the capacitor device is the so-called integral method and the signal obtained is the average charging time. What should we pay attention to when using refrigerated optical fiber spectrometer?
1、注意光電倍增管產生的信號需要放大
1. Attention should be paid to the amplification of the signal generated by the photomultiplier tube.
因此，重要的需要注意的是，光電轉換裝置產生的光電流與光的強度線性相關(光電流與光電倍增管產生的光強度的關系在光作用下可能不是線性的)，并且光電流和電容的電壓之間的關系是已知的。直接讀數光譜儀的光電倍增管產生的信號非常微弱，因此必須放大，使用直接讀數光譜儀測量放大信號，但無論如何，每個放大器都是由改變所獲得的小信號來控制大信號的變化，定量很可能推動測量儀器設備的工作。在制冷型光纖光譜儀設備中，我們主要使用設備室低頻弱功率放大設備，為什么叫低頻？其實所稱的低頻是指在音頻范圍內的操作頻率。
Therefore, it is important to note that the photocurrent generated by the photoelectric conversion device is linearly related to the intensity of light (the relationship between photocurrent and the intensity of light produced by the photomultiplier tube may not be linear under the action of light), and the relationship between photocurrent and the voltage of the capacitor is known. The signal produced by the photomultiplier tube of the direct reading spectrometer is very weak, so it must be amplified. The amplified signal must be measured by the direct reading spectrometer. However, each amplifier controls the change of the large signal by changing the small signal obtained. Quantitative analysis is likely to promote the work of the measuring instrument and equipment. In the refrigerated optical fiber spectrometer equipment, we mainly use the equipment room low frequency weak power amplifier equipment, why is it called low frequency? In fact, the so-called low frequency refers to the operating frequency in the audio range.
2、注意其分析方法要基于光譜法的原理
2. Note that the analysis method should be based on the principle of spectral method.
光電直讀光譜學的基本原理及其建立的分析方法是基于光譜法的基本原理及其實驗技術，只有測量參數和數據處理方法是不同。激發光源等離子體中的原子濃度決定了直讀光譜儀發射光譜的譜線強度。制冷型光纖光譜儀分析方法依賴于光電倍增器將光信號的強度轉換為電信號。有更多的儀器設備使用光電倍增器輸出光流到積分電容器裝置充電，測量制冷型光纖光譜儀集成電容器裝置電壓表示線法強度。
The basic principle of photoelectric direct reading spectroscopy and its analysis method are based on the basic principle of spectroscopy and its experimental technology. Only the measurement parameters and data processing methods are different. The atomic concentration in the plasma of the excitation source determines the spectral intensity of the emission spectrum of the direct reading spectrometer. The analysis method of refrigerated optical fiber spectrometer depends on the photomultiplier to convert the intensity of optical signal into electrical signal. More instruments and equipment use photomultiplier to output light flow to integral capacitor device to charge, and measure the voltage of refrigeration type optical fiber spectrometer integrated capacitor device to indicate the line strength.
供應質量好的光譜儀還有高靈敏度的超高能空心陰極燈和多元件燈，空心陰極燈本身也是一定的使用壽命。石墨管是石墨爐原子吸收分析中最重要的消耗材料。其它如火焰系統霧化器、毛細管注射管也是火焰原子吸收分析的主要耗材。因此，制冷型光纖光譜儀的基本要求是，積分電容器裝置上的電壓與光信號的強度呈線性關系。
The spectrograph with good quality is also provided with ultra-high energy hollow cathode lamp and multi-component lamp with high sensitivity, and hollow cathode lamp itself has a certain service life. Graphite tube is the most important consumable material in graphite furnace atomic absorption analysis. Other consumables such as flame atomizer and capillary injection tube are also the main consumables for flame atomic absorption analysis. Therefore, the basic requirement of the refrigerated optical fiber spectrometer is that the voltage on the integrated capacitor device is linearly related to the intensity of the optical signal.
