Product Description
***The 235ATS is designed for analysts requiring nitrous oxide to run Al, Si, Ga, Ge Ba, Be, Ti, Va, Zr, Nb, Mo, Hf, Ta, and W. The automated gas box allows for push button oxidant change-over from Air to Nitrous oxide for safety. The 235ATS also features a flame detector which will turn the gases off shall the flame extinguish***

The New 235ATS will continue Buck's long tradition of making single beam AAS with in-line Deuterium background correction. The simple optical design gives these systems superior energy, and better results than double beam AA systems. The unique design also allows our instruments to have a smaller footprint and a lower cost.
