Product Overview

Ammonium dihydrogen phosphate from the Puratronic™ line represents the pinnacle of purity for demanding laboratory applications, offering a metals basis purity of 99.995% that ensures minimal interference in sensitive analytical procedures. This crystalline solid is meticulously produced under controlled conditions to eliminate trace metal contaminants, making it ideal for applications where even parts-per-billion impurities can compromise results. The compound’s precise stoichiometry and consistent particle size distribution enhance reproducibility in experimental protocols, while its stable chemical nature allows for long-term storage without degradation. Unlike standard reagent grades, this Puratronic™ version undergoes additional purification steps to remove residual metals like iron, copper, and lead that commonly plague lower-grade phosphates. Its high solubility in water (370 g/L at 20°C) enables easy preparation of standard solutions, while the ammonium component provides a buffered pH environment that’s particularly valuable in biological and environmental testing. The material is packaged under inert atmosphere to prevent moisture absorption and oxidation, with each batch accompanied by a comprehensive certificate of analysis detailing impurity profiles. For researchers requiring absolute confidence in their phosphate source, this product eliminates variables that could skew data in ICP-MS, AA spectroscopy, or other trace-level analytical techniques.

FAQs

1. What is the difference between Puratronic™ grade and standard ACS grade ammonium dihydrogen phosphate?

Puratronic™ grade undergoes additional purification to achieve 99.995% metals basis purity, while ACS grade typically meets 99% purity with higher trace metal content that may interfere with sensitive analyses.

2. Can this product be used for preparing phosphate buffers in molecular biology applications?

Yes, its high purity and low trace metal content make it suitable for biological buffers where metal ion contamination could affect enzyme activity or protein stability.

3. What is the typical shelf life when stored under recommended conditions?

When kept in its original packaging at room temperature in a dry environment, the product remains stable for at least 3 years from the date of manufacture.

4. Is this ammonium dihydrogen phosphate compatible with HPLC mobile phase preparation?

Its ultra-low metal content makes it excellent for HPLC applications, particularly when analyzing metal-sensitive compounds or using UV detection where impurities could cause baseline noise.

5. What alternatives exist if I need a phosphate source with even lower anion impurities?

For applications requiring ultra-low anion content, consider our electronic grade ammonium phosphate or phosphoric acid solutions that undergo additional anion purification steps.
