Certified internal standard solution
Certified internal standard solution for adding to mixtures for NMR acquisition.
Chenomx sells certified internal standard solution for adding to mixtures for NMR acquisition and analysis using Chenomx NMR Suite. These solutions are certified for concentration accuracy using a separate NIST certified standard. This rigorous process was designed to eliminate concentration errors due to the hygroscopic nature of DSS salt.
We recommend our customers to use 10% of our certified ISTD solution with their samples. (for example 70 uL IS-1 or 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).
Note: IS-2 is offered since deuterated DSS has a simpler NMR 1D signature making it easier to work with using the Chenomx software.
