NIUMAG
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.
Basic Parameters:
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.
