NMR Analyzer, model NM120-Analyst

    The NMR Analyzer, model NM120-Analyst

Introduction

The model NMI20-Analyst is a spectrometer for analysis and images for research in different fields. It has been designed and developed by Niumag Corporation and was first marketed in 2007. It can be used in various fields such as petroleum, food, agriculture, medicine, biology etc. The excellent characteristics listed below include image functions and analysis together. The analysis is quick and accurate, high quality reproducibility and high stability. The images are of good quality with an easy and friendly operation. It has a very competitive relation quality to price. As a scientific research instrument the NM120 Analyst has been in the local market by expertos due to its excellent performance and established capacity. The NM120-Analyst has been sold in various Chinese provinces and has won the prize for 'The high technology product of Shanghai' due to the approval of so many customers.

Characteristics

• Operating system based on Windows. The Central frequency and the 90º and 180º pulse widths can be adjusted automatically.
• The spectrometer is controlled by a professional industrial computer increasing its stability.
• The PSG in the spectrometer can realise multi-sequence pulse functions.
• The independant spectrometer NMdigI assures the high stability and powerful functions of the NM120 Analyst.
• The spectrometer, that can be used for human images, include PSG, DDS, DAC and ADC. It also offers multi-slice and it not only produces normal images in 2D/3D, but also can produce multi-slice 2D images from randomised angles.
• Images in 3D function, and another function for the reconstruction of the image.
• Oriental large magnet that assures the system's high reproducibility and performance.
• Open MRI software, friendly user interface easy to use with adjustable parameters, may get and save thr original data from the K space and the interchange the K space by the FFT manually.
• Powerful inversion multi-exponent software is optional, capable of managing correctly T1/T2/T2* analysing relaxation times and relation in a sample.
• In the CPMG pulse sequence, the number of the largest echo peak can be upto 20000, the greatest number of the data sampling is 1 million, and the shortest echo time is 160us, then the T2 time can measure in a range of 80us to 14s.
• The NMR technique is non destructive allowing the total recovery of the sample.
• It's operation is friendly and easy. In most cases the samples do not need preparation whilst in other cases the preparation is minimum. The calibration is easy and needs very few samples.
• The data search funcction is simple and friendly, the huge database has many functins including classify, compare, count and the data can be exported to Excel for processing.
• Good fidelity, the standard deviation will not exceed 0,5% in 50 days.
• The quality of the small images of small samples is excellent, the image extremes are clear and the contrast is adjustable using the gradients.
