Product Description
When it comes to high-performance liquid chromatography (HPLC), the purity of your reagents can make or break your results. The Ammonia Solution 25% For HPLC from Merck is specifically formulated to meet the stringent demands of modern laboratories. Whether you’re a student running routine analyses or a researcher pushing the boundaries of scientific discovery, this solution delivers consistent performance with minimal background interference.
HPLC-grade ammonia solution is essential for applications where even trace impurities can skew data. This 25% concentration is optimized for mobile phase preparation, pH adjustment, and gradient elution in reverse-phase HPLC. Unlike technical-grade alternatives, this solution undergoes rigorous purification to remove metals, organics, and other contaminants that could compromise your chromatographic peaks.
What sets this product apart is its reliability. Merck’s reputation for quality ensures that each batch meets strict specifications, so you can trust your results without second-guessing your reagents. The 250 ml pack size is perfect for labs with moderate usage, balancing cost efficiency with freshness—no more worrying about degraded solutions from oversized bottles.
Upgrade your HPLC workflow with eqipped’s curated selection of high-purity solvents and reagents.
For educators, this ammonia solution is an excellent teaching tool. Its consistent behavior helps students understand the impact of mobile phase composition on retention times and peak resolution. The clear labeling and Merck’s documentation also make it easier to incorporate into lab protocols and SOPs.
Safety note: Ammonia solution is corrosive and hazardous. Always handle with appropriate PPE (gloves, goggles, lab coat) in a well-ventilated area. Store in a cool, dry place away from incompatible substances.
FAQs
What makes HPLC-grade ammonia different from regular ammonia?
HPLC-grade ammonia undergoes additional purification to remove impurities that could interfere with chromatographic analysis, ensuring accurate and reproducible results.
Can I use this ammonia solution for LC-MS applications?
While suitable for many HPLC applications, for LC-MS you may need a specialized LC-MS grade solution to prevent ion suppression. Check your method requirements.
How long does a 250 ml bottle typically last in a research lab?
Usage varies, but for most HPLC applications, a 250 ml bottle lasts 2-4 months with regular use, making it a cost-effective choice for small to medium labs.
Is this ammonia solution suitable for pH adjustment in buffer preparation?
Yes, its precise concentration and high purity make it ideal for preparing buffers where accurate pH control is critical.
What safety precautions should I take when handling this solution?
Always wear nitrile gloves, safety goggles, and a lab coat. Work in a fume hood and have an eyewash station nearby. Avoid skin contact and inhalation of vapors.
