Thank you for your interest in the Tosoh Bioscience GPC Survey brought to you by the EcoSEC GPC System.

Due to a record-breaking number of responses, we can no longer offer a free solvent-savings bottle cap in return for the completion of this survey. Your responses are important to us and we do ask you to please fill out the survey.

Note: The GPC User Survey is intended for bona fide users of HPLC/GPC systems used to characterize the molecular weight distribution of polymers.
