Product description : Heparin is a commonly used anticoagulant, especially in clinical biochemical and chemical measurement experiments. It is recommended as an anticoagulant for chemical measurements in blood or plasma testing, as it has minimal chelating properties, minimal interference with water, and relatively low cation concentration. Heparin is the preferred anticoagulant for measuring pH, blood gas, electrolyte, and ionic calcium. Heparin lithium However, heparin should not be used for coagulation or hematological tests. Heparin salts are most commonly used for blood sample collection, namely sodium salts and lithium salts. Heparin sodium and heparin lithium are mainly used for anticoagulation, because the ions they bind to are different, so their degree of dissociation varies. When testing other ions (such as sodium), heparin lithium is least likely to interfere with the results. Although both heparin sodium and heparin lithium can provide reliable results in testing, heparin lithium has shown higher accuracy in electrolyte testing in blood testing compared to heparin sodium testing. The use of heparin sodium for electrolyte testing may overestimate sodium levels. Why are there differences between heparin sodium and heparin lithium anticoagulants in electrolyte analysis? The reasons can be explored from two aspects: chemical and physical properties. Although sodium and lithium are both alkali metals, lithium is composed of two stable isotopes, Li6 and Li7. Li has a conductivity of 10E6/cm: 0.108, a nuclear charge of 3, and an outer electron layer of 1. Lithium has low density and viscosity, while Li7 has the advantage of a small neutron capture surface, only 6.2% of sodium. Lithium has fewer electrons and is relatively stable, so its binding and aggregation speed with PLT is slower than that with heparin sodium. The conductivity of sodium is 10E6/cm: 0.21, with a nuclear charge of 11 and an outer electron layer of 6. Comparing the three values of the two elements, lithium has more stable chemical properties than sodium. Sodium has a higher nuclear charge and aggregates more quickly with negatively charged PLT than heparin lithium. Desheng Company is a professional manufacturer of heparin lithium and heparin sodium.
