Chenomx sells certified internal standard solution for adding to mixtures for NMR acquisition and analysis using Chenomx NMR Suite. This solution is 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.
