Product Overview

Sulphuric Acid 96% ACIPUR For Trace Metal Analysis (CAS No. 7664-93-9) is sulphuric acid supplied at the stated 96% strength for trace-metal analytical workflows requiring controlled reagent background. The acid provides strong protonating and digestion conditions and can be used to establish sulphate-containing matrices for sample decomposition or preparation where the chosen instrumental or wet-chemical method is compatible. The concentration basis is not inferred beyond the submitted 96% designation.

The ACIPUR trace-metal-analysis grade is intended to minimise contribution of metallic contaminants from the acid itself during trace-level sample preparation, digestion, blank preparation and matrix adjustment. It is relevant to AAS, ICP-OES, ICP-MS and related elemental techniques only where sulphuric acid is appropriate to the specific method and analytes.

Typical Applications

• Trace-metal sample digestion where sulphuric acid is method-compatible.
• Preparation of low-background acidic reagent blanks.
• Matrix acidification for AAS and plasma-spectrometric analysis.
• Decomposition of suitable environmental, industrial and material samples.
• Preparation of trace-analysis reagent and wash solutions where sulphate is acceptable.
• Investigation and control of reagent-derived metal background.

Common Synonyms

• Sulfuric acid
• Oil of vitriol

Storage Conditions

Keep tightly closed to minimise moisture exchange and environmental contamination that could compromise concentration or trace-metal cleanliness. Use dedicated clean dispensing practices appropriate to trace-element work to minimise introduction of metallic and particulate contaminants.
