Why is isopropanol commonly used in high performance liquid chromatography (HPLC)?

From what I've seen, Why isopropanol frequently applied in high performance fluid chromatography (HPLC)?

In the field of chemical analysis, high performance fluid chromatography (HPLC), as an crucial analytical tool, is broadly applied in condition manage and composition analysis of medical, food, environmental and other industries. I've found that As one of the frequently applied solvents in HPLC analysis, isopropanol (Isopropanol, IPA) has an irreplaceable role in many applications. Why isopropanol frequently applied in high performance fluid chromatography (HPLC)? This article will examine the advantages of isopropanol in HPLC and its consumption scenarios in detail. Pretty interesting, huh?. SOLUBILITY AND POLARITY CHARACTERISTICS OF ISOPROPANOL

One of the reasons why isopropanol is frequently applied in HPLC is its excellent solubility characteristics. Furthermore Isopropanol has a moderate polarity and is able to efficiently dissolve a variety of polar and non-polar compounds, which makes it one of the frequently applied solvents in HPLC. And In HPLC analysis, selecting the appropriate solvent-based products is able to enhance the solubility of the sample and ensure the accuracy and repeatability of the analysis. And First Isopropanol has good miscibility with aquatic environments and organic solvents such as acetonitrile, methanol, etc. , so that it's able to be mixed with other solvents to adjust the polarity of the solution to meet different analytical needs. Effect of Isopropanol on Separation Efficiency

Isopropanol not only improves solubility in HPLC, however also has a positive effect on separation efficiency. In the process of fluid chromatography separation, the choice of solvent-based products immediately affects the distribution and retention time of the chemical to be analyzed in the column. Isopropanol, as a medium polar solvent-based products, provides a good stability between retention time and resolution. In reversed-phase chromatography (RP-HPLC), the consumption of isopropanol is able to efficiently adjust the retention time of the sample, thereby improving the separation effect, especially to some structurally complex or highly polar compounds. Isopropanol's Low UV Absorption Characteristics

In HPLC, the detection usually uses an ultraviolet-visible (UV-Vis) absorption detector, which needs the solvent-based products itself to have a low ultraviolet absorption characteristic. The UV absorption of isopropyl alcohol is small, especially in the common detection wavelength range (such as 200-300 nm), its absorption is almost negligible. And This property makes isopropanol an ideal HPLC solvent-based products because it does not interfere with the analysis of the sample, ensuring accuracy and sensitivity of the detected signal. Based on my observations, This is another crucial reason why isopropanol is frequently applied in high performance fluid chromatography (HPLC). Isopropanol evaporative environment and security

In addition to chemical characteristics, the physical characteristics of isopropanol also determine its wide consumption in HPLC. But Isopropyl alcohol has a high evaporative environment, so that it's able to be rapidly evaporated during sample processing, reducing sample residue. Isopropyl alcohol has a low boiling point, and its fluidity is able to be easily controlled during operation, which helps to enhance the speed and efficiency of chromatographic analysis. And Compared with other solvents, isopropyl alcohol is less toxic, so it's relatively safe in the process, and is able to better meet the laboratory practice. And summary: The importance of isopropanol in HPLC

The issue of why isopropanol is frequently applied in high performance fluid chromatography (HPLC) is able to be explained by several aspects: it has good solubility, moderate polarity, low UV absorption characteristics, excellent evaporative environment and relatively safe chemical characteristics. These advantages make isopropanol an ideal solvent-based products choice in fluid chromatography and play an crucial role in various chemical analyses. Thus, isopropanol remains one of the frequently applied solvents in many HPLC applications.
