Custom Standards

Inorganic CRMs Made to Your Specs

Unless otherwise specified, chromium is present in our products as chromium (III).

Custom standards are Inorganic Ventures' specialty. Our catalog reveals only a fraction of the inorganic reference materials we can prepare. More than two thirds of our business is devoted entirely to preparing custom standards. As the leading manufacturer of custom inorganic standards, we've produced tens of thousands of unique blends for laboratories worldwide. It's our area of expertise, and perhaps the most prominent way in which we flex to your specs.

How We Flex

Inorganic Ventures has been a super-dependable source of our custom calibration standards for ICP-MS. Whenever we have had chemical compatibility questions, Dr. Gaines has spent time carefully and thoroughly responding to these questions. The result is that we have a succinct set of custom standards that are efficient to use, dependable and long-lasting. Inorganic Ventures is a big part of backing up our company motto: "Numbers you can count on."

Speed and credibility often come at a higher price. But you'd be surprised how elastic that price can be. We offer individualized purchasing plans and other special discounts to better accommodate any budget — just ask. We're happy to manufacture nearly any solution in bulk quantities. This prevents the need for repeat labor, which in turn saves you money. Plus, there's no waiting when you reorder the material — it'll ship the day you order.
