Product Overview
METHANOL 99.8% For HPLC is a high-purity solvent designed for demanding laboratory applications, particularly high-performance liquid chromatography (HPLC). With a minimum purity of 99.8%, this methanol ensures minimal interference in analytical procedures, delivering consistent and reliable results. Its low UV absorbance and residual impurity levels make it ideal for sensitive detection methods, including UV-Vis spectroscopy and mass spectrometry. The solvent undergoes rigorous quality control to meet stringent HPLC-grade standards, ensuring batch-to-batch consistency. Its hygroscopic nature necessitates proper storage in tightly sealed containers to prevent moisture absorption, which could compromise performance. Compatible with most organic solvents and aqueous systems, this methanol is a versatile choice for sample preparation, mobile phase formulation, and general lab use. The absence of stabilizers or additives guarantees purity, making it suitable for trace analysis and research-grade applications.
FAQs
1. What is the shelf life of HPLC-grade methanol?
When stored in a cool, dry place in its original sealed container, HPLC-grade methanol has a shelf life of 24 months from the date of manufacture. Exposure to air or moisture can reduce its stability.
2. Can this methanol be used for GC-MS applications?
Yes, this methanol is suitable for GC-MS due to its high purity and low residual impurities, which minimize background noise and signal interference during analysis.
3. Is this methanol compatible with plastic containers?
While methanol is generally compatible with HDPE or PTFE containers, prolonged storage in certain plastics may cause leaching. Glass or specially rated plastic containers are recommended for long-term storage.
4. What precautions should be taken while handling this solvent?
Methanol is highly flammable and toxic. Use in a well-ventilated area, wear appropriate PPE (gloves, goggles, lab coat), and avoid inhalation or skin contact. Store away from ignition sources.
5. How does this compare to ACS-grade methanol?
HPLC-grade methanol has stricter purity requirements, particularly for UV absorbance and residual impurities, making it superior for chromatography. ACS-grade is suitable for general lab use but may not meet HPLC sensitivity needs.
