带塞曼背景校正的石墨炉原子吸收光谱仪
Blood, seawater and high-salt digests produce background that deuterium correction struggles with. This furnace uses Zeeman correction, in transverse or longitudinal field orientation, to handle background up to 2.5 A while keeping limits at 0.01–1 µg/L. A L'vov platform and 5–50 µL sample volumes come standard. Choose it for regulated trace methods on difficult matrices.
