Dear coleagues,I'm interested in detection limits and quantification limits for Ca, Mg, K and Li, determined by ICP MS.Is it possible to have a LOD and LOQ of 0.1 mg/l, respectively 1,0 mg/l for Ca in water samples? And 0.5 mg/l, respectively 5 mg/l for K?For Li, Hg, Pb and As, the LOD and LOQ were 0.01 ug/l, respectively 0.001ug/l. So LOQ is 10 times higher than LOD.I found these values in an article. But  I new that the LOQ can be equal, but not higher than the LOD.In these conditions, can we…See More
