Instrumental Applications\"><\/noscript><\/noscript><\/noscript><\/noscript><\/div>\n<p>Analytical precision demands uncompromising reagent purity. Modern trace analysis techniques rely on acids and bases free from contaminants to achieve accurate results. Suprapur\u00ae acids and bases from Merck are specially engineered to meet the strictest industry standards, helping laboratories minimize interference in sensitive instruments and ensure confidence in every measurement. Explore how these products address the challenges in sample preparation and trace analysis.<\/p>\n<h2>Benefits of Suprapur\u00ae acids and bases<\/h2>\n<ul>\n<li><strong>Reduced measurement interference:<\/strong> Helps minimize interference in modern instrumental trace analysis by using acids and bases with low impurities during sample preparation.<\/li>\n<li><strong>Reliable trace-level suitability:<\/strong> Supports trace analysis in the ng\/g (ppb) range for laboratories working with very low analyte levels.<\/li>\n<li><strong>Confidence in sensitive techniques:<\/strong> Provides a suitable choice for highly sophisticated instrumental trace analysis such as AAS, ICP-OES, ICP-MS, F-AAS, and GF-AAS.<\/li>\n<li><strong>Greater result confidence:<\/strong> Supports accurate analytical outcomes through reagents offered for trace analysis with ppb impurities and manufactured under strict quality control for sensitive techniques.<\/li>\n<li><strong>Clear impurity transparency:<\/strong> Gives users access to an extensive impurity profile through the Certificate of Analysis.<\/li>\n<li><strong>Application-fit selection:<\/strong> Allows laboratories to choose an appropriate purity grade for instrumental trace analysis based on application needs, target, and budget.<\/li>\n<\/ul>\n<h2>Features of Suprapur\u00ae acids and bases<\/h2>\n<ul>\n<li><strong>Product range:<\/strong> Suprapur\u00ae acids and bases include high purity acids, bases, and water.<\/li>\n<li><strong>Portfolio position:<\/strong> These products are part of a portfolio optimized to offer acids and bases with the lowest inorganic impurities.<\/li>\n<li><strong>Purity grade options:<\/strong> Suprapur acids and bases are offered in different grades for instrumental trace analysis.<\/li>\n<li><strong>Specified impurity parameters:<\/strong> Suprapur\u00ae acids and bases have specified parameters in the ppb range.<\/li>\n<li><strong>Container materials:<\/strong> Suprapur\u00ae acids are filled in borosilicate glass or extra pure PE bottles, and Suprapur\u00ae acids for instrumental trace analysis are also offered in borosilicate glass or extra pure HDPE material.<\/li>\n<li><strong>Bottle preparation:<\/strong> The bottles are cleaned and pre-conditioned before filling.<\/li>\n<li><strong>Quality control:<\/strong> Quality control is performed after filling.<\/li>\n<li><strong>Packaging format:<\/strong> Suprapur\u00ae reagents are packed in a stable outer-box.<\/li>\n<li><strong>Documentation:<\/strong> The Certificate of Analysis provides an extensive impurity profile.<\/li>\n<\/ul>\n<h2>Applications and usage of Suprapur\u00ae acids and bases<\/h2>\n<ul>\n<li><strong>Wet digestion and sample preparation:<\/strong> Digestion with acids is often used during sample preparation, and the reagents used for sample preparation have an important impact on the outcome of the measurement.<\/li>\n<li><strong>Modern instrumental trace analysis:<\/strong> In modern instrumental trace analysis, any impurity can disturb the measurement, so acids with low impurities should be used to minimize interference on the instrument signal.<\/li>\n<li><strong>Instrumental trace analysis use:<\/strong> High purity Suprapur\u00ae acids and bases are designed for instrumental trace analysis and are suitable for trace analysis in the ng\/g (ppb) range.<\/li>\n<li><strong>Inorganic trace elements analysis:<\/strong> Suprapur acids and bases are ideal for inorganic trace elements analysis where low inorganic impurities are required.<\/li>\n<li><strong>Atomic absorption techniques:<\/strong> These reagents are suitable for highly sophisticated instrumental trace analysis such as AAS, including Flame Atomic Absorption Spectrometry (F-AAS) and Graphite Furnace Atomic Absorption Spectrometry (GF-AAS).<\/li>\n<li><strong>ICP-based analysis:<\/strong> Suprapur acids and bases are also intended for use with Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) and Inductively Coupled Plasma Mass Spectrometry (ICP-MS).<\/li>\n<li><strong>Application-aligned reagent selection:<\/strong> For wet digestion, the available high purity Suprapur\u00ae acids and bases are offered in different grades, packaging sizes, and packaging materials so laboratories can choose according to application, target, and budget.<\/li>\n<\/ul>\n<h2>Available Suprapur\u00ae acids and bases<\/h2>\n<div
