AN-NIR-042
Quantification of USP heparin units using near-infrared spectroscopy
Summary
Heparin acts as an efficient anticoagulant and, in addition to direct injection, is also used as a lock-flush solution for rinsing catheters. Vis-NIR spectroscopy can be used to determine the strength of contaminated and purified heparin. This Application Note demonstrates that heparin strength can be determined reliably with Vis-NIR spectroscopy.
