Time-domain NMR (TD-NMR) is accepted throughout the world for determining the oil and water in seeds (ISO 10565), and residues after crushing (ISO 10632). In particular, it has value:
Where the accuracy and reliability of the measurement is important for determining crop value
Where high throughput is required for testing laboratories
Where a variety of seeds, many of which are non-standard, need to be measured for research
For measuring sunflower seeds where TD-NMR is generally accepted to be the most reliable method
Two versions of the MQC+ are available for this application:
The MQC+ Large Seed Analyser is normally used for large seeds and seed volumes (40 and 80ml), typically used for determining the value of agricultural produce
The MQC+ Small Seed Analyser is for single seeds and small seed volumes (up to 14ml), typically used for breeding and other research.
For high throughput of samples and greater control of your production.
Less prone to calibration disruption due to different seed size, colour, origin etc.
Simple intuitive software, suitable for unskilled users, which guides the operator through the analysis.
Users can carry out routine cleaning to ensure consistent results.
Standard Method
TD-NMR is used in the ISO 10565 method, which has been adopted by FOSFA (Federation of Oils, Seeds and Fats Associations).
Minimal sample preparation
Simply transfer the sample into a tube, weigh then analyse in seconds. It can be measured ‘as-is’ without grinding.
Accurate
TD-NMR is a bulk measurement technique and so measures all the oil in the sample regardless of the particle size.
