Absolute and Relative Quantification

Absolute and relative quantification – flexible applications

Our quantitative NMR spectroscopy enables fast, direct, and non-destructive determination of purity and content – without the need for external calibration standards. Using internal standards, we deliver highly precise results for a wide range of soluble compounds.

In addition to absolute quantification, we also offer relative quantification by NMR – ideal for polymers and complex matrices. This method saves time and effort, enables precise comparative measurements, and reliably supports process control.

Absolute Quantification

Classical purity and content determination by quantitative NMR spectroscopy using an internal standard delivers highly precise results. It is a direct, fast, non-destructive, and accurate method that does not require external calibration standards and can be applied to a broad range of compounds – if it’s soluble, we can analyze it!

Quantification Relative to the Main Substance

Quantification by qNMR relative to the main substance can be highly advantageous. In just one measurement, we can determine impurities relative to the API or analyze the degree of substitution in polymers.
