Product Overview
Acetonitrile, 99.9% extra dry over molecular sieve, is a high-purity solvent designed for moisture-sensitive applications where trace water content can compromise results. This AcroSeal®-packaged acetonitrile undergoes rigorous drying over molecular sieves to achieve ultra-low water levels (<10 ppm), ensuring consistent performance in high-sensitivity techniques like HPLC, LC-MS, and UV/Vis spectroscopy. The solvent’s exceptional transparency in the UV range (down to 190 nm) and low reactivity make it indispensable for gradient elution, sample preparation, and mobile phase formulation. Packaged under nitrogen in amber glass bottles with PTFE-lined caps, it minimizes contamination and oxidation, preserving purity during storage. The AcroSeal® technology provides an additional barrier against moisture ingress, extending shelf life even after opening. Compatible with most organic and aqueous systems, this grade meets ACS, Reagent, and HPLC specifications, offering batch-to-batch reproducibility for critical analytical workflows. Its low viscosity and high eluotropic strength further enhance chromatographic efficiency, reducing analysis time without sacrificing resolution.
FAQs
1. What is the water content in this extra dry acetonitrile?
The water content is less than 10 ppm, achieved through molecular sieve drying and sealed packaging to prevent reabsorption.
2. Can this acetonitrile be used for LC-MS applications?
Yes, its 99.9% purity and ultra-low water content make it suitable for LC-MS, including ESI and APCI ionization modes.
3. How should this solvent be stored to maintain purity?
Store tightly sealed in the original amber glass bottle at room temperature, away from direct sunlight and moisture sources.
4. Is this acetonitrile compatible with gradient HPLC methods?
Yes, its low UV cutoff and consistent composition ensure reliable baseline stability in gradient elution.
5. What alternatives exist for less moisture-sensitive applications?
For general lab use, standard HPLC-grade acetonitrile (99.9%) without molecular sieve drying is a cost-effective alternative.
