PREP mc2 is an instrument intended for semipreparative fractionating polymers by molar mass or by composition (TREF and CRYSTAF approaches). Samples are put into the vessels and the fractionation is performed automatically according to the selected method conditions in less than 24 hours. OverviewPREP mc2 is an instrument intended for semipreparative fractionating polymers by molar mass or by composition (TREF and CRYSTAF approaches). Samples are put into the vessels and the fractionation is performed automatically according to the selected method conditions in less than 24 hours. Molar Mass fractionation is based on the solvent interaction with the polymer chains through a solvent/non-solvent separation approach. Polydispersity of resulting fractions can be very narrow.

The PREP mc2 Software automates the fractionation process by composition TREF, CRYSTAF or by Molar Mass solvent-non solvent approaches. The corresponding separation method is selected from the PREP mc2 Software before starting the process, as well as a set of parameters involved in the fractionation, which can be configured by the user to get the desired separation conditions: such as the number of fractions obtained, volume, temperature steps (when fractionating by composition), solvent-non solvent percentages (when fractionating by molar mass) or cleaning cycles.
The PREP mc2 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 mc2 Software, like in all Polymer Char’s instruments, without handling manually hot solvents and very useful as a fast diagnosis tool. As a result, every part of the instrument can be operated remotely. This manual mode is especially useful in the PREP mc2 instrument 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.
