This article uses PerkinElmer atomic absorption spectrometer PinAAcleD900 to quickly and accurately analyze lead, cadmium, copper, nickel, zinc, and chromium specified in the national soil quality standard GB15618-2018.

Flame graphite furnace integrated automatic sampler, precise positioning, effectively improves analysis efficiency

High intensity continuous light source deuterium lamp and innovative deuterium lamp automatic balancing mechanism ensure excellent background effect when analyzing complex matrix samples

Combined with PerkinElmer's original rapid soil digestion method, this article tested soil standards: the linear correlation coefficients of the calibration curves were all greater than 0.999; The measured values of each element in the three soil reference material samples are within the recognized range.
