Frequently Asked Questions
Q: What is the difference between AR Grade and HPLC Grade Methanol?
A: While both are high purity, HPLC Grade undergoes additional purification and testing (like UV absorbance tests) to ensure it is free from impurities that could interfere with sensitive HPLC detectors. Our AR grade is suitable for many HPLC applications, but for ultra-sensitive work, HPLC grade is recommended.
Q: What are the main uses of Methanol in a lab?
A: It is a workhorse solvent used as a mobile phase in HPLC, a solvent for spectroscopy (UV/Vis), in organic synthesis, as a fuel for alcohol burners, and for cleaning and rinsing laboratory glassware.
Q: How should I store Methanol safely?
A: Store in a tightly sealed container in a cool, dry, well-ventilated area designated for flammable liquids. Keep it away from heat, sparks, open flames, and strong oxidizing agents.
