The MQC+ benchtop NMR analyser measures oil, water, fluorine and solid fat in a variety of samples and is typically used for quality assurance and quality control.

Fast, Accurate, Non-destructive Analysis

Analysis using the MQC+ takes from a few seconds to a few minutes, which means that a high volume of samples can be processed quickly and efficiently. As NMR signals are generated from all parts of the sample not just the surface, even if they are opaque, more accurate measurements are guaranteed. NMR measurements do not damage the sample in any way, so samples can be kept for repeat measurements or to be analysed using other techniques.

Minimal Sample Preparation with no Hazardous Solvents or Chemicals

Grinding or other forms of sample preparation are rarely needed. Samples are simply transferred into a sample tube, conditioned and then analysed. The MQC+ NMR method does not require solvents or other chemicals, removing the need for fume cabinets, specially trained staff and expensive disposal procedures.

Easy to use

The MQC+ benchtop NMR analyser is very easy to use. Lab technicians will be productive in no time as minimal training is required. The software provides step by step operator guidance with clear on-screen prompts; there are also status indicator lights at the sample chamber entrance. Operator prompts can be customised, and displayed in any language.

In many industries there is a requirement to accurately, reliably and simply measure the amount of a viscous or liquid component in the presence of other solid materials. The MQC+ meets this requirement with a technology that avoids the needs to separate the different phases; making sample preparation trivial, removes the need for extensive operator training, and provides fast accurate results. That means a more consistent product from your manufacturing operations, better process control, and reduced costs.

The MQC+ analyser measures oil, water, fluorine and solid fat in a variety of samples and is typically used for quality assurance and quality control. MQC+ is available as three models: MQC+ 23, MQC+ 5 and MQC+ F. MQC+ 23 is used for smaller samples and high sensitivity applications; for example it is used to measure small amounts of oil applied to artificial fibres and fabrics to enhance their properties. MQC+ 5 is used for large samples, typically agricultural products; for example, it measures the oil, and moisture content in oilseeds. This is important because in some regions the higher the oil content, the more valuable the crop which affects the revenue received by farmers for their harvest. MQC+ F is used to measure fluorine in toothpaste and minerals, for example.

The MQC+ is a compact benchtop Nuclear Magnetic Resonance (NMR) analyser. With over 35 years' experience in the benchtop NMR business, we understand that the most important qualities of a lab analyser are ease of use, accuracy, reliability and serviceability. The MQC+ has been designed to fully meet all these requirements.

Industry : Applications

  • Food : Oil in snack foods, total fat in chocolate, fat in foodstuffs and Solid Fat Content (SFC)
  • Agriculture : Oil and moisture in oilseeds and their residues, oil in dried olive paste and oil in dried palm mesocarp
  • Textile : Spin finish on fibre, also known as Oil Pick-Up (OPU), Finish on Yarn (FoY), lubricant and avivage
  • Consumer products : Lotion on fabric and fluorine in toothpaste
  • Petroleum : Hydrogen content in fuel, oil content in waxes and wax content in petroleum products
  • Polymers : Xylene solubles in polypropylene, plasticiser in PVC, polymer density & crystallinity, oil in rubber and fluorine content
  • Other : Fluorine in powders (e.g. fluorspar, alumina) and limestone filler in asphalt

The MQC+ NMR analyser replaces wet chemical analysis, which uses hazardous chemicals. It allows you to measure more samples much faster. Unlike wet chemical methods, the MQC+ doesn't destroy the sample being measured. It can also measure physical properties including crystallinity and density of polymers.

The MQC+ benchtop NMR analyser offers several important advantages over other laboratory analytical techniques:

  • Accuracy
    NMR signals are generated from all parts of the sample not just the surface, even if they are opaque, guaranteeing more accurate measurements.
  • Easy to use
    MQC+ is designed to make the job of technicians working in QA/QC labs easier. It simplifies the analysis process and removes the need for extensive operator training.
  • Non-destructive
    NMR measurements do not damage the sample in any way, so samples can be kept for repeat measurements or to be analysed using other techniques.
  • Cost-efficient
    Low maintenance and running costs, just requires mains power.
  • Minimal Sample Preparation
    Simply transfer the sample into a tube, condition it then analyse it. Grinding or other forms of sample preparation are rarely needed.
  • No Hazardous Solvents or Chemicals Involved
    The NMR method doesn’t require solvents or other chemicals, removing the need for fume cabinets, specially trained staff and expensive disposal procedures.
  • Rapid Analysis
    Analysis takes from a few minutes to a few seconds, which means you can process a high volume of samples in the lab quickly and efficiently.

Easy to use

The single biggest benefit of MQC* is that it is so easy to use. Lab technicians will be productive in no time as minimal training is required.

The software provides step by step operator guidance with clear on-screen prompts; there are also status indicator lights at the sample chamber entrance. Operator prompts can be customised, and displayed in any language.

MQC* can be fitted with a variety of robust sample holders, commonly known as probes, to easily handle different applications and sample sizes. The sample holders can be changed easily in a matter of minutes.

MQC* s space saving internal PC uses Windows-based software, a flat screen monitor and a standard PC keyboard. USB ports are provided for easy software upgrades and to allow data to be saved externally.

Every MQC* system is supplied with all software, hardware and sampling accessories for the application it will be used for.

Reliable and easy to maintain

MQC* has been designed with the minimal number of component parts, making it easy to set up and maintain. Advanced electronics enables the spectrometer's firmware to be upgraded so the instrument can be kept up to date with the latest improvements. It also incorporates advanced self diagnostic routines so that any faults can be quickly localised to save time and money.

The spectrometer continuously logs all diagnostic parameters in a database which means that it is possible to monitor the history and health of the instrument indefinitely. Diagnostics data can be accessed either over the internet or saved to a file and emailed to a service engineer.

Low Maintenance

MQC* is easy to look after: the PC fan filter is easily accessible for cleaning. The robust sample holders are also easy to remove and all MQC*23 holders have open ended bottoms for easy cleaning. MQC* has an automatic magnetic field optimisation routine, which ensures the best results whilst also reducing costs and increasing uptime as it means a service visit is not required.

Easy to calibrate

MQC* measurements are generally insensitive to colour, particle size and other physical properties of the sample. Calibrations are always linear so you only need a handful of samples. Once established, the calibrations are robust and rarely need to be repeated.

Saves Space

Despite its small magnet size, MQC*23 has a large sample space and high field strength, so it can be used to measure larger samples as well as offering high sensitivity.

Fast and Efficient

MQC* can make over 100 measurements a day, which is up to 250 times faster than using wet chemical analysis. Switching to MQC* will save you time and money thanks to its speed and efficiency.

A platform for the future

The MQC* analyser builds on the success of its predecessor by retaining many of its features, including reliable easy-to-use quality control software. However MQC* has been designed with the potential for enhanced capability. It belongs to a new generation of magnetic resonance instruments incorporating a high performance spectrometer. This means it will benefit from future enhancements to the platform for years to come.
