Certified standard solutions
Chenomx sells certified standard solutions for improved NMR acquisition and analysis using Chenomx NMR Suite. Please review our Standard Operating Procedures for detailed instructions on sample preparation, data acquisition, and profiling.
IS-2 Chenomx Internal Standard - DSS-d6
We recommend our customers use 10% of our certified ISTD solution for their samples (for example 70 uL IS-2 + 630 uL sample for a total of 700 uL available for the NMR-ready sample in the case of typical 5 mm tubes).
QC1 - Quality Control
Chenomx now offers a Quality Control Solution to confirm optimum protocol and procedures for your NMR sample preparation. This solution consists of 5.0 mM each of Sodium Acetate, Sodium Formate, Valine, and Glycine (selected for their stability over normal storage conditions).
Add the QC along with your own internal standard to make an NMR-ready sample. Then run the sample in the NMR instrument with your typical acquisition parameters, and analyze your results in Chenomx NMR Suite. The resulting spectrum will provide a controlled standard that can be used to confirm:
- Efficacy of water suppression
- Shimming Results
- Errors in internal standard concentration
- Errors in sample preparation
- Use of recommended NMR data acquisition parameters
Your results should be 5.0 mM per each of the 4 compounds with an error of ± 10% after adjusting for dilution of the internal standard.
