Introducing the Oxford Instruments Magnetic Resonance : 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.
Key Features
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. 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.
No hazardous solvents or chemicals involved
The MQC+ does not require solvents which are hazardous to use & costly to dispose of.
Non-destructive
he 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
Robot can be paused, and door opened, during a run to add more samples; the racks may be removed for loading.
Flexibility
A range of sample sizes are available on both the Large and Small Seed Analyser.

Specifications
Options
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, e.g. sunflower, soy, groundnut, 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. Watch the MQ-Auto in action.
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. |
