产品简介

内置计算机数据处理和液晶显示屏:采用高集成的微机化数字电路,稳定可靠。具有积分保持、峰高、峰面积、自动调零、氘灯扣背景、多种线性非线性曲线拟合、屏幕显示各种参数和工作曲线、打印报告等功能,同时设有外接个人计算机接口。

可靠的基线稳定性:优化设计的双光束系统能补偿光源漂移,温度变化引起波长的漂移(具有消除波长漂移对基线稳定性影响的功能)和电子线路漂移,因此,具有可靠的基线稳定性,阴极灯不必长期预热就可立即分析样品,是分析多种元素和快速分析样品的优秀仪器。

测量的高精度:由于气路系统装有精密的稳压、稳流装置、火焰稳定、噪音小、独特设计的细光束从火焰中通过,确保分析测试精密度高,特征浓度低。

高能量的光路:采用全反射光学系统,全波段消色差,并将光源的圆光斑通过光学变换,成为长光斑进入狭缝,从而提高了双光束的光通量。

长寿命耐腐蚀的原子化系统:燃烧头采用耐腐蚀、快速热平衡新型钛合金材料,不用水冷却就能达到测量灵敏度稳定的要求。

多功能的分析方式:可做火焰吸收、火焰发射、石墨炉原子吸收(有AS-3020自动进样器可配)和氢化物发生法。

安全可靠的气路系统:具有快速气体转换和安全防护装置,既可做空气-乙炔火焰分析又可做笑气火焰分析,使分析元素扩大到60余种。
