Diazyme's Lithium Assay provides a convenient, stable, non-caustic low cost alternative to expensive ISE and highly caustic alkaline Lithium methods. Diazyme's
Lithium Assay demonstrates an excellent correlation with ISE methods and offers excellent precision CV% of <5% and a measuring range from 0.19 mmol/L – 3.0
mmol/L. The assay is not interfered by the following substances at indicated concentrations: Na+ 200 mM, NH4+ 0.5 mM, Ca2+ 4.0 mM, Mg2+ 2.0 mM, ascorbic
acid 5.0 mM, 0.25 mM Zn2+, 0.25 mM Fe3+, 0.25 mM Cu2+, 10 mM K+, Triglycerides 1000 mg/dL, conjugated bilirubin 20 mg/dL and unconjugated bilirubin 45 mg/
dL, Ascorbic Acid 5 mM and hemoglobin 500 mg/dL.
