Background of the change
Resonac has been offering a concentrate, IC NY-5, used specifically as IC I-524A eluent in Japanese market. However, due to a significant decrease in its demand, the product was discontinued at the end of 2022.
We have been using the IC NY-5 for product inspection and shipping solvent of IC I-524A. As mentioned above, upon the discontinuation of IC NY-5 sales, we recognized the necessity of more precise description of the IC I-524A inspection and shipping eluent composition. We hope the new description should help the users to prepare the same eluent used at its product inspection.
