Popis: A turbidimetric method has been used for quantification of fractionated heparin (FH) in pharmaceutical dosage. The UV detection at two wavelengths (290 and 500 nm) showed a significant increase in sensitivity of the method, specificity, and linearity to range 5.0-50.0 µg mL-1 and 50.0-200.0 µg mL-1, respectively (r < 0.99). At both wavelengths, the method was precise (inter-assay CV < 5.0%, and intra-assay CV < 3.0%), accurate (maximum deviation of ± 12%), and robust to the parameters evaluated. Turbidimetry proved to be easy, inexpensive and relatively fast. The results obtained attest to the reliability of the method.
