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.该仪器有一个电动8空心阴极灯炮塔，允许自动定位和优化每个空心阴极灯的软件。
- 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.燃烧器的燃气(C2H2)的气体流量控制也直接从软件中进行，从而使仪器能够优化选择分析的最佳分析参数。
- Two methods of background correction are available. The first utilises a Deuterium Arc lamp and the second is the proven method of Self Reversal.有两种背景校正方法。第一种是使用氘弧光灯，第二种是已被证实的自我逆转方法。
- High precision minimal optics ensures maximum light throughput to the computer controlled Czerny-Turner Monochromator.高精度，最小光学，确保最大的光吞吐量计算机控制的Czerny-特纳单色器.
- The location of the wavelength and peak selection is automatically controlled from the software.波长位置和峰值选择由软件自动控制。
- The spectral bandwidth is automated and is available with a choice of five slit sizes.光谱带宽是自动化的，可以选择五个狭缝大小。
- 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. 该软件对光电倍增管探测器的电子参数、空心阴极灯电流以及吸光度和背景能量的平衡进行了控制。
- The ignition of the flame is computer controlled and the various safety interlocks offer a very safe operating system.火焰的点火由计算机控制，各种安全联锁提供了非常安全的操作系统。
