Icon is geared both technically and quantitatively to service the research needs of the agronomist and soil scientist in Nitrogen-15 research. Our personnel have been involved in supplying ¹⁵N for most of the larger field trials in recent years, and this experience enables us to adapt our production to meet most requirements. The more commonly used compounds are detailed in this catalog. We will also blend to specific enrichments upon request.

The most common form is as crystalline powder; however, material can be
supplied in solution form and as pellets.

We realize that requirements are of a seasonal nature, and as such, can create an excessive demand on our raw material and synthetic capabilities.

To ensure the timely receipt of materials ordered from Icon, we offer a Material Hold Program, whereby the requirements of researchers are stockpiled ahead of time and therefore can be shipped immediately upon demand should weather conditions break or threaten to affect application plans. (We regretfully must stipulate that this applies to catalog-listed enrichments only).
