General description
- Derived from renewable feedstocks with bio-carbon content certification
- Similar chromatographic resolution, reproducibility, and baseline stability
- Drop-in replacement: no method redevelopment required
LiChrosolv® hypergrade is accurately tested for LC-MS suitability and meets all the requirements of modern LC-MS ionization methods (ESI/APCI - positive and negative mode). Thanks to their low level of ionic background and low ion suppression, LiChrosolv® hypergrade solvents provide high reproducibility and high ionization efficiency. The packaging material has been improved to meet LC-MS quality requirements perfectly.
Application
- Mobile Phase in HPLC: Widely utilized as a polar solvent in both reversed-phase and normal-phase HPLC, suitable for various types of analytes.
- Gradient Elution: Ideal for gradient elution techniques, enhancing the resolution and separation efficiency of complex mixtures.
- Pharmaceutical Quality Control: Used in the quality control of pharmaceutical products to analyze formulations, stability, and degradation products.
- Food and Beverage Analysis: Employed in HPLC for the analysis of additives, preservatives, and flavor compounds in food and beverage samples.
- Natural Product Analysis: Utilized in the separation and characterization of natural products, such as alkaloids and flavonoids, from plant extracts.
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
LiChrosolv® bio-based solvents are derived from renewable feedstocks and verified through bio-carbon content certification. They provide comparable chromatographic performance to conventional solvents; same resolution, reproducibility, and baseline stability; and function as drop-in replacements requiring no method redevelopment.
Available with Data Matrix Code
This high-quality LCMS-grade solvent now features a unique Data Matrix Code on its label, providing digital access to essential product information such as batchnumber, 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.
