B&A® AMMONIUM SULFATE, PURIFIED

You can tell the difference. Just compare the typical analysis given at right, with an analysis of the ammonium sulfate you're currently using. You'll see that the exceptionally low levels of iron, lead and arsenic in B&A ammonium sulfate provide the superior quality you need for high purity end products.
