NMI20-Analyst is an analyzing and imaging spectrometer for research in different fields. It can be used in various study fields just like petroleum, food, agriculture, medicine, biology and so on. The outstanding characters list below:
have imaging and analysis function together; quick analysis and precise outcome; high reproduction quality and high stability; excellent image quality; easy operation; high performance-to-price ratio.
As a scientific research instrument, NMI20-Analyst was generally approbated by domestic expert because of its excellent performance and steady capability.
Features:
Characteristic:
- Software operation based on Windows operation system. Center frequency and the width of 90 degree pulse and 180 degree pulse can be adjusted automatically.
- Professional industry control computer as spectrometer platform, it makes the instrument more stability.
- The PSG in spectrometer can realize multi pulse sequence function.
- Independent innovation NMdigI spectrometer can make sure the instruments high stability and powerful function.
- The spectrometer system which can even used in human imaging, it including PSG, DDS,DAC and ADC. It can inspire multi slices, not only can realize the normal 2D/3D imaging, but also can realize the 2D random angle multi-slice imaging.
- 3D imaging function, image re-construction function.
- Oriental big magnet, which ensures the steady, reliability, fidelity.
- Openness MRI software, friendly operating interface, adjustable parameters, can collect and save the K space original data, and the FFT interchange of K space data can be done manually .
- Powerful multi-exponent inversion fitting software is optional, which can do T1/T2/T2* inversion and fitting, correctly measuring different groups’ relaxation time and ratio in one sample.
- In CPMG pulse sequence, the biggest echo wave peak number can reach to 20000, the biggest sampling data number is 1 million, the shortest echo time is 160us, and thus the T2 time can be measuring in a range of 80us to 14s.
- Non-destructive: the excitation pulse electromagnetic wave is lower than only 30 MHz, it won’t hurt the sample any more, and especially it’s good for seeds R&D.
- Operation is convenient and easy: in most test item, the samples do not need prepreparation or only take little time to preparation. In quota test, it only needs six or above six samples.
- Data search is convenient: the huge capacity data base has dispart, classify, compare, count functions, the data can also load in excel to process.
- Good fidelity: standard deviation won’t exceed 0.5% in 50 days.
- Wonderful imaging quality of small sample, clear sample edge, high organize contrast gradient.
