Product Overview
This 99.5% HPLC-gradient isopropanol is engineered for high-performance liquid chromatography (HPLC) and other demanding analytical applications where purity and consistency are critical. The solvent undergoes rigorous purification to eliminate UV-absorbing impurities, ensuring baseline stability and accurate peak detection in gradient separations. Its low water content (<0.1%) and minimal residual solvents make it suitable for sensitive detectors, including UV/Vis and mass spectrometry. The product is filtered through 0.22µm membranes to remove particulate matter, preventing column clogging and system contamination. Its controlled evaporation rate and miscibility with water and organic solvents enhance versatility in mobile phase preparation. The solvent is packaged in amber glass bottles to prevent photodegradation, preserving its stability during storage. Compatible with most HPLC systems, this isopropanol meets or exceeds ACS, Reagent, and Pharmacopeia standards for analytical-grade solvents. Its neutral pH and absence of stabilizers ensure reliable performance in both isocratic and gradient elution methods.
FAQs
1. Can this isopropanol be used for LC-MS applications?
Yes, the high purity and low impurity profile make it suitable for LC-MS, though we recommend verifying compatibility with your specific instrument settings.
2. What is the shelf life of this HPLC-grade isopropanol?
When stored unopened in its original container at room temperature, the shelf life is 24 months from the date of manufacture.
3. Is this solvent compatible with UHPLC systems?
The 0.22µm filtration and ultra-low particulate count make it compatible with UHPLC systems, but always check your system’s solvent requirements.
4. How does this compare to ACS-grade isopropanol?
HPLC-grade has stricter purity specifications, particularly for UV absorbance and residual impurities, making it superior for chromatographic applications.
5. What precautions should be taken during storage?
Store in a cool, dry place away from direct sunlight and ignition sources. Keep the container tightly sealed to prevent moisture absorption.
