Spray drying is an attractive continuous process that transforms liquids (solutions, emulsions, slurries, pastes, or melts) into micron-sized particles, allowing for adjustments in spray volume, shape, porosity, concentration, and chemical composition. It is widely used in fields such as materials, chemicals, food, and pharmaceuticals. Typical applications include: ■ Coatings (titania, alumina, zirconia, yttria coatings) ■ Advanced ceramics (such as new superconducting ceramics) ■ Toners and magnetic tapes ■ Inhalable dry powders ■ Nanoparticle drugs, among others. *For more details, please refer to the catalog or contact us.

Related Device: Fractionation Chromatography System Pure C-815 Cholesterol and its esters, which are components of biological membranes, are utilized as industrial raw materials in cosmetics, pharmaceuticals, and liquid crystals. When performing gradient fractionation purification for compounds that are difficult to detect with UV detectors, methods are selected using low wavelength UV detection such as 210 nm or ELSD (Evaporative Light Scattering Detector). ELSD is a fractionation purification method that overcomes the disadvantages of UV-triggered fractionation due to the absence of baseline drift and T0 peaks. By adopting ELSD & UV double triggering, it enables complementary fractionation purification using both ELSD and UV. 【Issues with Low Wavelength UV Triggered Fractionation】 ■ The baseline drifts due to the solvent's own absorption used in the mobile phase, making it difficult to detect sample peaks. ■ Baseline rises consistently during gradient steps, leading to the baseline being recognized as a peak, which significantly increases purification time and fraction volume. *For more details, please refer to the PDF document or feel free to contact us.

Related Products: Fractionation Chromatography System Pure C-815 To achieve high-purity precision purification of mid-sized compounds such as peptides, reverse phase LC is commonly applied, and simple rough purification after synthesis or extraction is generally performed using methods like SPE (solid-phase extraction). In rough purification using SPE, adjusting the pH of the solvent allows for easy separation of anions, cations, and non-ions, but separating components of the same ionic type is challenging. Rough purification by flash chromatography enables selective and rapid separation and purification of target compounds through optimization of mobile phase and gradient conditions. 【Mechanism of Rough Purification by SPE】 ■ Easy separation of anions, cations, and non-ions ■ Difficult separation of components of the same ionic type (anions, cations, non-ions) *For more details, please refer to the PDF document or feel free to contact us.
