PQ001 NMR Analyzing System is a cost effective design which includes the most advanced spectrometer system, to provide superior analysis at a reasonable price. Thanks to its reliability and accuracy, the PQ001 has been highly accepted worldwide by experts in this field, since it was launched into the market in 2008. As a specialized analyzing instrument of high performance-price ratio, the product can be widely used in the fields such as petro chemistry, food, energy, biology, agriculture, botany and more.
With the minimal number of component parts, PQ001 is easy to set up and maintain. Inside the electronics unit, the main modules are arranged in pods, which are conveniently accessible and removable through a back panel. The advanced new electronics of the PQ001 allows the instrument’s internal firmware to be upgraded through a DVD, ensuring that users can easily be kept up to date with improvements and advances of PQ001. The instrument also maintains an operation and performance log on its own website, which is accessible across the Internet.
Features:
Characteristic:
- “one box” design, save the lab space, and operation convenient .
- Professional industry control computer as spectrometer platform, fast data processing, and good anti-jamming ability, steady and durable.
- Independent innovation NMdigI spectrometer can make sure the instruments’ high stability and powerful function.
- Oriental big magnet, which ensures the steady, reliability, fidelity.
- 15mm diameter coil is standard config, it can be expanded to 25mm diameter coil, which expand the capacity and reduce the error caused by Individual difference.
- 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.
- Fast: to get the content of water and oil, detect once only needs less than 20us.
- Auto-search and adjust for the centre frequency, the width of 90° and 180° pulse.
- Good fidelity: standard deviation won’t exceed 0.5%.
- 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 and processing is convenient: windows operation system, the huge capacity data base has dispart, classify, compare, count functions, the data can also load in Excel to process.
- 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.
- Customizable: hardware and software can be developed according to customer’s individual needs.
- It can be fitted with variety advanced device, like var-temperature system, var-pressure system.
