Polymer Additive Analyser is a dedicated system based on high-performance liquid chromatography (HPLC) with ultraviolet/visible (UV/VIS) detection to analyze different additives such as antioxidants & and Erucamide Slip in polymer formulations. HPLC is a chromatographic technique that is used to separate, identify and quantify components of a mixture. The separation in HPLC occurs due to the differential partitioning of analytes between the mobile phase (liquid) and the stationary phase (solid particles in the column). This partitioning is influenced by factors such as the chemical nature of the analytes, the composition of the mobile phase, and the properties of the stationary phase. HPLC operation parameters play a crucial role in its applications to various areas, and it is generally operated in either the normal phase or reversed phase, depending upon the nature of the sample and analytes. Almost all petroleum and petrochemical applications are carried out in the normal phase using polar stationary and non-polar mobile phases.
