TD-NMR for QA/QC

Why TD-NMR?

TD‑NMR is well suited to QA/QC measurements as it replaces laborious wet chemistry methods and avoids the use of hazardous chemicals. The instrument is typically dedicated to one or more specific applications, ensuring consistent and reliable results. Its software is user‑friendly, requiring little training or prior experience, and methods are straightforward, often based on simple linear calibrations using only a few samples. In addition, the technique is non‑destructive, allowing samples to be preserved after analysis.

MQC+ Fat Analyser measures fat in a wide range of products, including:

  • Snack and processed foods: Potato/corn chips, nuts, chocolate, cocoa products, and food ingredients
  • Powders and dry products: Milk powder, infant formula, nutritional products, and dried pet/animal feeds
  • Specialty and other foods: Fish meal and dried fish (NMKL method 199, 2014) and other dried foodstuffs

MQC+ Solid Fat Analyser measures Solid Fat Content (SFC) of various edible oils and fats equilibrated at different temperatures to provide a melting profile (AOCS Cd 16b-93, ISO 8292-1:2008, IUPAC 2.150).

MQC+ Oilseed Analyser measures oil and water in seeds (ISO 10565) and residues after extraction (ISO 10632), providing value where:

  • Accuracy matters: Reliable measurement for determining crop value
  • Throughput is critical: Supports high-volume testing in manual or automated labs
  • Flexibility is needed: Handles a wide range of standard and non-standard seeds, including sunflower where TD‑NMR is widely trusted

MQC+ Large Seed Analyser is designed for bulk crop measurement, while the MQC+ Small Seed Analyser is ideal for research-scale samples.

MQC+ Spin Finish Analyser delivers fast, clean, and accurate measurement of spin finish on fibre—also known as Oil Pick-Up (OPU), Finish on Yarn (FOY), or Lubricant on Thread (LOT). These oil-based coatings reduce static, minimise friction, and improve fibre performance.

Accurate coating measurement is also critical for optimising textile and nonwoven manufacturing. In addition, MQC+ measures:

  • Specialty coatings: Elastomeric/rubber (e.g. latex) and fluorinated coatings (e.g. teflon)
  • Finish removal: Important for medical fabrics and pre-treatment before further coating
  • Low-level finishes: Detects coating levels below the limits of solvent extraction methods
Textiles

MQC+ Analyser provides fast, non-destructive measurement of key composition parameters, supporting quality control and material performance assessment across a wide range of applications.

  • Hydrogen content in fuels: an important indicator of the combustion properties
  • Wax content in petroleum products: required to avoid blockages in pipelines and processing
  • Oil content in waxes: a QA/QC tool to regulate the hardness/softness of products
  • Polymer composition and properties: analyse xylene solubles in polypropylene, polyethylene density, plasticiser content in PVC, oil content in rubber and more
Polymers

MQC+ Analyser provides fast, non-destructive measurement of key composition parameters across minerals, pharmaceuticals, and industrial materials, supporting quality control, process optimisation and compliance.

  • Fluorine analysis: Measure fluorine content in fluorspar, alumina/cryolite for aluminium production, polymers, and toothpaste
  • Moisture measurement: Quantify moisture in pharmaceutical tablets and powders
  • Construction materials: Assess limestone filler content in asphalt and bitumen
  • Environmental & industrial: Measure fat, oil, and grease (FOG) in filtered wastewater systems

Explore MQC+

MQC+ is a compact benchtop Nuclear Magnetic Resonance (NMR) analyser available in three models: MQC+23, MQC+5, and MQC+F. The MQC+23 is designed for small samples and high-sensitivity applications, such as measuring trace oil on artificial fibres and fabrics. The MQC+5 is suited to larger samples, typically agricultural products, measuring oil and moisture in oilseeds. The MQC+F measures fluorine in toothpaste and minerals.

It supports a range of robust sample holders (probes) for different applications and sizes, which can be swapped in minutes. Each system includes all required software and sampling accessories, with optional lab equipment such as dry heaters, water baths, balances, and autosamplers also available.

Why It Stands Apart

Accurate

Accurate

NMR signals originate from the entire sample volume, not just the surface. This enables reliable and accurate measurements, even for opaque or heterogeneous materials.

Non-destructive

Non-destructive

NMR analysis leaves the sample completely unchanged, allowing repeat measurements, long-term storage, or further analysis using complementary techniques if required.

No hazardous chemicals

No hazardous chemicals

TD‑NMR requires no solvents or reagents, eliminating chemical hazards, reducing regulatory burden, and removing the need for fume hoods, specialist handling, or waste disposal.

Simple linear calibration

Simple linear calibration

Calibration is straightforward, requiring only a small number of reference samples that span the expected concentration range for robust and reliable quantification.

Minimal sample prep

Minimal sample prep

Sample handling is simple: transfer into a tube, allow temperature equilibration, and analyse. Grinding, dissolution, or complex pre-treatment steps are usually unnecessary.

Rapid analysis

Rapid analysis

Measurements are completed in seconds to minutes, enabling high sample throughput and fast decision-making in routine QA/QC laboratory environments.
