General description
LiChrosolv®solvents are specially formulated to meet the demanding needs of analytical HPLC applications. With exceptional UV transmittance, minimal particle count, and controlled acidity and alkalinity, our solvents ensure reproducible separations every time. The low evaporation residue level further enhances their performance, making them the ideal choice for high-quality results. The product line includes both "gradient grade" and "isocratic grade" solvents, specifically designed to reduce the gradient effect during separations. This tailored approach allows for optimal consistency and accuracy in your analytical processes, helping you achieve the best possible outcomes in your chromatography work.
This bio-based solvent for LC offers the same precision and reliability you trust, now with more sustainability.
- Derived from renewable feedstocks with bio-carbon content certification
- Similar chromatographic resolution, reproducibility, and baseline stability
- Drop-in replacement: no method redevelopment required
Application
- Reversed-Phase HPLC: Commonly used as a mobile phase component for the separation of a wide range of compounds, including pharmaceuticals, environmental pollutants, and biomolecules.
- Gradient Elution: Ideal for gradient elution techniques, enhancing the resolution, and separation efficiency of complex mixtures.
- Pharmaceutical Analysis: Frequently employed in the analysis of active pharmaceutical ingredients (APIs) and their impurities, ensuring compliance with regulatory standards.
- Biological Sample Analysis: Used for the analysis of proteins, peptides, and metabolites in biological samples, facilitating accurate quantification and identification.
- Environmental Monitoring: Applied in the HPLC analysis of environmental samples to detect and quantify contaminants in water, soil, and air.
Features and Benefits
- High Purity: Formulated with minimal impurities, ensuring reliable and reproducible results essential for sensitive analytical applications.
- Excellent UV Transparency: Provides optimal UV transmittance, facilitating accurate detection and enhancing sensitivity in HPLC analyses.
- Low Evaporation Residue: Minimizes contamination risk, leading to cleaner separations and improved analytical reliability.
- Batch-to-Batch Consistency: Ensures uniform quality and performance across different production batches, enhancing reproducibility, and confidence in analytical results.

Other Notes
Available with Data Matrix Code
This high-quality HPLC-grade solvent now features a unique Data Matrix Code on its label, providing digital access to essential product information such as batch number, product number, and expiry date. Unlike standard barcodes, our DMCs feature a unique serial number for each bottle, enabling you to monitor and trace every bottle individually. With standard barcodes, all bottles from the same batch look identical. Our solution gives you true bottle-level traceability for greater control and compliance in the lab. Know more about our data matrix code-labeled HPLC-grade solvents.
