Distilled for Trace Metal Determination ®
BAKER INSTRA-ANALYZED' Acids Improved Blank Definition 'BAKER INSTRA-ANALYZED'® Acids are purified by J.T. Baker to assure low, consistent blank values in trace element determination. They pro vide significant blank definition over "reagent" grade acids and are espe cially suited to meet the demands of multi-element trace determinations by AA and plasma emission (ICP and DCP) spectrography.
