NMR Contrast Agent Relaxivity Analyzer PQ001-Relax

Analysing the relaxivity of contrast agents using nuclear magnetic resonance (NMR) is one of the earliest and most established application areas of this technology. The PQ001-Relax NMR Contrast Agent Relaxivity Analyzer is a dedicated instrument for relaxivity testing. Unlike methods that infer relaxivity indirectly through image differences, the PQ001-Relax enables direct measurement, providing more precise relaxivity values.Equipped with professional testing software, the system delivers a full range of relaxation time parameters. It offers researchers a convenient, rapid, and reliable solution for accurate relaxivity evaluation.
