Restek (USA) has just released the only certified reference materials (CRMs) developed specifically for EPA Method 525.3. These standards include all the required analytes and no unnecessary compounds, and they are formulated to provide maximum stability in concentrations convenient for dilution. Restek CRMs are manufactured and QC-tested in our ISO-accredited labs and are quantitatively tested to confirm composition and ensure quality. The new 525.3 standards join Restek’s existing 525.2 standards, so a complete, specially formulated standards set is now available for both versions of the method.
