Spectrasol History & Rationale
A Biography of Success

 

In 1989 we published a paper showing that we could use the Spectrasol Zeolite (Z) reagent to neutralize the hydrofluoric acid (HF) in a zeolite digest and analyze the digest for silicon by ICP using a Meinhard nebulizer, glass spray chamber and glass torch.

That was a first!

Not having to switch to an HF resistant torch assembly; no use of boric acid which clogs nebulizers and etches glassware. The results from this landmark publication are shown below.

From there we went on to develop the Spectrasol Coal Fly Ash (CFA) reagents to prepare samples containing fluoride insoluble elements like calcium and rare earths.

Lately, we have extended the use of the Spectrasol reagents to include such applications as reducing ArCl+ interferences in ICP-MS analysis and the dissolution of milk products without the need for digestion.
