PQ001 Oil & Moisture Content NMR Analyzer
The PQ001 NMR Analyzer was launched in 2008. After years of upgrading, PQ001 has many advantages such as small size, high precision, good repeatability, good stability and excellent cost/benefit performance. Based on these advantages, PQ001 has been widely used in the determination of oil & moisture content in agriculture areas.
- Permanent magnet
- 12MHz Frequency
- Ø40mm Probe
Principle of Oil/Moisture Content Testing
The hard pulse echo sequence originating from CPMG sequence with only one echo count, namely only one 180° pulse after the 90° pulse, shown in Figure, is applied to measure the oil and/or Moisture content in seed by means of NMR technology. After 90° pulse, FID signal appears and after 180° pulse, echo signal appears.
