MQC+ Oilseed Analyser

Easier, Faster, More Accurate Analysis of Oilseeds


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.


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.


TD-NMR is a bulk measurement technique and so measures all the oil in the sample regardless of the particle size. TD-NMR is the method of choice for sunflower seeds since it is unaffected by colour; as such it is used as an official USDA GIPSA method.

High throughput

Auto-weighing feature improves the ergonomics of analysis on the MQC+ Large Seed Analyser; this allows operators to measure 100’s of samples per day.


The same sample may be measured repeatedly by the MQC+, analysed by a destructive method, used for growing or preserved.

Automation option

Automated analysis of up to 125 samples using the MQC+ Small Seed Analyser with MQ-Auto.

Simple linear calibration

Oil and water calibrations may be obtained using just three samples.


A range of sample sizes are available on both the Large and Small Seed Analyser.

No hazardous solvents or chemicals involved

The MQC+ does not require solvents which are hazardous to use & costly to dispose of.



The range of probe sizes and associated sample sizes are given in the table below:

MQC+ Model Sample size (Diameter / Volume) Typical applications
Large Seed analyser 51 mm / 80 ml and 40 mm / 40 ml Large seeds and nuts, e.g. sunflower, soy, groundnut (peanut), almond, castor, jatropha. Large volumes of rape and linseed.
Small Seed Analyser 26 mm / 14 ml and 18 mm / 8 ml Small volumes, single seeds (e.g. corn, jatropha) and automation.
10 mm / 1 ml and 5 mm / 0.2 ml Single seeds and small seed volumes (e.g. arabidopsis, camelina for research).

To increase laboratory productivity and efficiency, the MQC+ Small Seed Analyser can be used with the MQ-Auto sample automation system (8 or 14ml volumes only). The MQ-Auto is based around a high-performance robot arm and a range of sample racks and conditioning stations. A balance is required and the bar code reader (for sample identification) is strongly recommended for this application.
