Chenomx NMR Suite - 代谢组学解决方案
· 好消息:ChenomxV10.1中的新增功能给客户带来了福利
· 来看看如何使用Chenomx Compound Builder模块来分析化合物?
Chenomx NMR Suite结合了复杂的化学和高等算法,可通过广泛的代谢物光谱模型库识别和量化NMR光谱中的代谢物。
Chenomx NMR分析软件可与综合光谱参考库一起使用,在一个集成的工作流程中识别和测量NMR光谱中可见化合物的浓度。该软件提供浓度测量、识别和光谱去卷积。
Chenomx NMR分析软件光谱参考库是根据通过NMR分析获得的数千个参考光谱开发的,用于识别和比较目的。参考库的pH值范围为4到9,NMR场强范围为400MHz到800MHz。
Chenomx NMR分析软件通过将光谱参考库“拟合”到实验光谱中的适当信号来发挥作用。该软件会自动调整参考库以反映样品和采集条件(pH、NMR场强、谱线宽度),并允许用于调整峰强度和位置以获得微调的浓度值。
拟合实验信号后,频谱的残差线就暴露出来了。分析软件将比较光谱参考库中的更多化合物,以分离和识别剩余的信号。

【英文介绍】
Chenomx NMR Suite combines sophisticated chemistry and advanced algorithms to identify and quantify metabolites in NMR spectra with an extensive library of spectral models of metabolites.
Used by Metabolomics researchers world-wide, Chenomx NMR Analysis Software works with comprehensive Spectral Reference Libraries to both identify and measure concentrations of compounds visible in the NMR spectra, all in one integrated workflow. This patented software offers best-in-class concentration measurement, identification and advanced de-convolution of spectra.
The Chenomx NMR Analysis SoftwareSpectral Reference Libraries are developed from thousands of reference spectra obtained through NMR analysis and used for identification and comparison purposes. The Reference Libraries are available from pH 4 through 9 and NMR field strengths from 400 MHz through 800 MHz.
Chenomx NMR Analysis Software functions by 'fitting' the Spectral Reference Library to the appropriate signals within the experimental spectrum. The software automatically adjusts the Reference Library to reflect the sample and acquisition conditions (pH, NMR field strength, spectra line width) and allows the used to adjust peak intensity and location for fine-tuned concentration values.
After the experimental signal has been fit, the spectrum's residual line is exposed. The profiling software will compare more compounds from the Spectral Reference Library to isolate and identify the remaining signals.
Core Modules
Processor
The 'Processor' module lets you import a wide variety of NMR spectra into Chenomx NMR Suite. It also provides the standard processing tools needed to clean up and calibrate those spectra, so that you can more easily and accurately analyze them using the Profiler module.
Profiler
The 'Profiler' module lets you identify and quantify the contents of your mixture spectrum by comparing it to a compound library with hundreds of reference signatures.
Library Manager
The 'Library Manager' module lets you manage sets of compounds that are available to all other modules in Chenomx NMR Suite. This includes any custom compounds that you've created with Compound Builder, as well as all of the standard Chenomx Reference Compounds.
Spin Simulator
The 'Spin Simulator' module allows you to simulate an entire compound signature based on a few theoretical details. Just set a magnet frequency, then start solving coupling relationships and measuring j-value constants while your simulation updates itself in real time!
Professional Version Only
Compound Builder
The 'Compound Builder' module allows you to create your own custom compound signatures, complete with full quantitative information. These signatures can then be used when analyzing samples in Profiler.
Batch Functions
Batching significantly reduces processing time for large sample sizes. Batch Import/Batch Process applies processing steps to groups of samples; while Batch Fit/Batch Edit applies profiled compounds from a single spectra to an entire batch of spectra to reduce profiling time. Then, add stars, pins, and colors for labelling.
Spectral Binning
Binning reduces the number of variables by dividing spectra into a series of ppm regions, or bins; subsequent analysis involves the integrated area of these bins instead of the raw spectral data
COMPLETE Autofit
All-new Automatic Iterative Profiler that performs numerous, parallel approaches to a complete autofit of your NMR spectra and generates multiple CNX files with a recommended‘BEST’ fit.
