In analytical applications, chromatography is used to determine purity and/or identity. One of these chromatographic methods is HPLC. HPLC stands for high-performance liquid chromatography, a method in which the substance to be analyzed is pumped through a separation column with a running medium, the mobile phase (also called eluent). The separation column contains the stationary phase. Depending on the type of substance to be analyzed and the stationary phase used, separation is achieved by adsorption, partitioning or exchange processes, which can also occur simultaneously in one system. A significant advantage of HPLC is that it enables the analysis of soluble solid and liquid substance mixtures.

Chromasolv™ solvents from Honeywell

The Chromasolv product family offers a range of high-purity, high-quality chromatography solvents. The HPLC solvents undergo rigorous specification testing to ensure they are suitable for general and routine analysis. Two different grades of the Chromasolv solvent line are used for high performance liquid chromatography.

HPLC Grade: These solvents are characterized by high purity with high UV transmittance at all relevant wavelengths, low intrinsic fluorescence, low evaporation residue, and low acidity and alkalinity.

Gradient Grade: In addition to their suitability for UV and fluorescence detection, they are also specifically tested for their suitability for gradient separation. This ensures batch-consistent quality for gradient grade solvents.

The Chromasolv™ product line is characterized by high purity, stability and consistent quality from batch to batch. It provides users with high-quality solvents for use in HPLC. Honeywell consistently follows global standards for high purity requirements, as reflected in its ISO 9001 and RC 14001 certifications.
