Thousands of users worldwide enjoy the fast and accurate measurements made possible by the MQC and MQC+ range of Nuclear Magnetic Resonance (NMR) analysers. Laboratory productivity and efficiency are given an extra boost with the MQ-Auto, a robotic system that extends the working time of the MQC+ and frees laboratory staff for more intensive tasks.

The MQ-Auto system is based around a high-performance robot arm and a range of sample racks and conditioning stations. An optional balance can be incorporated for applications that require samples to be weighed, and a barcode reader is also available for sample identification

MQ-Auto is especially valuable for laboratories which require high throughput and/or relatively long measurement times, thus the technician can be relieved for other duties elsewhere. In addition, to the balance and bar code reader, the customer has a choice of racks and conditioning blocks, which may be defined by the application(s), as per the table below.

Safety and Operation

Operator safety is of course paramount with any electrical or mechanical installation, so comprehensive safety features have been built into the MQ-Auto. The robot arm itself is a so-called “collaborative robot”, designed to stop automatically if any obstruction (such as a human limb) is encountered in its path. In addition to this, the entire autosampler installation is housed in a transparent enclosure interlocked to shut down the robot arm if the door is opened. This two-level security protection ensures that the system can be operated safely with confidence.

The MQ-Auto is controlled by software running on either the Windows-10 internal computer of the MQC+ instrument, or on an external PC. The software allows samples to be run against different calibrations, and also allows operation to be paused mid-run for additional samples to be added. Optional barcodes can be attached to sample tubes to identify the sample and to store the tare weight of the tube for measurements that require weighing.

  • Compatible with both weighing and non-weighing methods, i.e. with and without a balance.
  • Measures up to 125 samples, 96 or 72 with conditioning dependent on probe size.
  • Different calibrations (and applications) may be loaded to the run list.
  • Two level security protection to ensure operator safety.
  • Robot can be paused, and door opened, during a run to add more samples; the racks may be removed for loading.
  • Choice of racks and conditioning blocks, which may be defined by the application(s), as per the table below.

The MQC+ is suitable for many applications in multiple industries:

Sample racks18mm (8ml) sample tubes26mm (14ml) sample tubes
Room temperature racks (maximum 4)Maximum 32 per rack*Maximum 32 per rack*
Heated blocks (maximum 4)Maximum 24 per block*Maximum 18 per block*

*Three positions must be reserved for a tuning sample and initialisation routines
