In the past, many types of researches have been performed to allow multi-element determinations using atomic absorption spectrometry. The first spectrometers developed for this purpose were proposed in the 1970s, using flame and furnace atomizers.

In the early 2000s, a spectrometer equipped with software that allows a fast selection of the hollow cathode lamps was introduced commercially. This equipment operates in a sequential mode, and it enables the determination of up to 16 elements. Many publications have reported its performance.

Over the years, many spectrometers were built adding new technologies, but they were discontinued due to low sensitivity, difficulty for background corrections, etc. However, all the efforts of the past have contributed to the development and consolidation of the high-resolution continuum source atomic absorption spectrometry (HR-CS AAS) using flame and furnace atomizers. This technique allows the establishment of sequential and simultaneous methods for determinations of many elements with high sensitivity and efficient background correction.

过去，已经进行了许多类型的研究，以允许使用原子吸收光谱法进行多元素测定。为此目的开发的第一台光谱仪是在1970年代提出的，使用了火焰和炉式雾化器。

在2000年代初期，一种装有软件的光谱仪可以快速选择空心阴极灯，并已在市场上推出。该设备以顺序模式运行，最多可以确定16个元素。许多出版物都报告了它的性能。

多年以来，许多光谱仪都是在增加新技术的基础上建造的，但由于灵敏度低，背景校正困难等原因而停产。但是，过去的所有努力都为高分辨率连续谱源的开发和整合做出了贡献。使用火焰和炉式雾化器的原子吸收光谱法（HR-CS AAS）。该技术允许建立用于测定许多元素的顺序和同时方法，具有高灵敏度和有效的背景校正。
