Request a Quotation PREP C20 Overview Fully Automated Column-based Preparative (PREP) Fractionation Equipment for Polymers. PREP C20 is a fully-automated preparative pilot-plant-type equipment designed to fractionate, in a column’s support, high amounts of polymer according to its Chemical Composition by a Temperature Rising Elution Fractionation (TREF) process, or according to its Molar Mass, by modifying the solvent strength through a solvent-non solvent combination, typically in isothermal conditions. A dry sample is put in a vessel and filled with solvent for dissolution. The sample solution is then loaded into a column where the crystallization takes place. The equipment fractionates the sample following the selected method’s conditions and the number of fractions, which can be eluted at the desired volumes. In the end, the vessel is rinsed and ready for the following fractionation. The main steps in the preparative fractionation process (dissolution, column loading, crystallization, elution, and fraction collection) are performed in an automatic mode, thus, avoiding the need for handling hot and large amounts of solvent. It is precisely in its capacity of fully automating the fractionation of large amounts of polymer where the system holds its major benefit. PREP C20 facilitates cross-fractionation studies (fractionation through TREF or Molar Mass and follow up analysis through GPC/SEC or TREF), that have been demonstrated to be a necessary tool to fully characterize resins. The fractions obtained can be further analyzed by spectroscopic techniques and can be used for micromechanical testing as well.

The PREP C20 software offers wide flexibility when setting the different conditions involved in the fractionation process: such as the number of fractions obtained, column loading volume, temperature steps or cleaning cycles. PREP C20 user just needs to weight the sample, put it inside the vessel, select the fractionation conditions and start the software. From this point on, the instrument performs the vessel filling with solvent, dissolution, column loading, crystallization, elution and fraction collection. The PREP C20 Software has been designed as a powerful Virtual Instrumentation interface to the instrument hardware, collecting all the sensors signals during the whole fractionation process as well as monitoring them in real-time, watching at the expected behaviors and warning the user about any abnormal issues during the fractionation. A manual mode is also available in the PREP C20 Software, like in all Polymer Char’s instruments, as a very useful tool for diagnosis. As a result, every part of the instrument can be operated remotely. This manual mode in an equipment with IR4 is especially useful when fractionating unknown or difficult samples, allowing to perform step by step fractionations, which provides the user all the flexibility to adapt the fractionation conditions to the sample requirements.
