Features

• The instrument has a motorised 8 hollow cathode lamp turret which allows the automatic positioning and optimisation of each hollow cathode lamp by the software.該儀器有一個電動8空心陰極燈炮塔，允許自動定位和優化每個空心陰極燈的軟件。
• The control of the gas flows for the fuel gas (C2H2) of the burner is also carried out directly from the software thus allowing optimisation of the instrument for the best analytical parameters for a selected analysis.燃燒器的燃氣(C2H2)的氣體流量控制也直接從軟件中進行，從而使儀器能夠優化選擇分析的最佳分析參數。
• Two methods of background correction are available. The first utilises a Deuterium Arc lamp and the second is the proven method of Self Reversal.有兩種背景校正方法。第一種是使用氘弧光燈，第二種是已被證實的自我逆轉方法。
• High precision minimal optics ensures maximum light throughput to the computer controlled Czerny-Turner Monochromator.高精度，最小光學，確保最大的光吞吐量計算機控制的Czerny-特納單色器.
• The location of the wavelength and peak selection is automatically controlled from the software.波長位置和峰值選擇由軟件自動控制。
• The spectral bandwidth is automated and is available with a choice of five slit sizes.光譜帶寬是自動化的，可以選擇五個狹縫大小。
• The electronic parameters for the photomultiplier tube detector, the hollow cathode lamp current and the balancing of the absorbance and background energies are controlled from the software.?該軟件對光電倍增管探測器的電子參數、空心陰極燈電流以及吸光度和背景能量的平衡進行了控制。
• The ignition of the flame is computer controlled and the various safety interlocks offer a very safe operating system.火焰的點火由計算機控制，各種安全聯鎖提供了非常安全的操作系統。
