Accurate SEC/GPC viscosity

​

Software that is easy to use for analytical and polymer chemists who need to effectively collect, manage, and report GPC data, Chromperfect GPC/SEC software is a unique software application that utilizes all of the custom reporting and data analysis routines of the Chromperfect Data system as well as providing features specific for managing your Size Exclusion Chromatography (SEC), and Gel Permeation Chromatography (GPC). Chromperfect GPC/SEC software can provide the answers you need about your polymer.

 

Justice Laboratory Software does not limit the user to only the one or two types of detectors, users are free to select the best of breed.

 

Designed to accommodate the broadest range of detectors you choose; RI, UV, or DVD can interface to Chromperfect. Chromperfect makes it easy to review and edit baselines and integration parameters.
