GPC Quattro gel permeation chromatography (GPC) Instrument by Pickering Laboratories, Inc.

• Fourfold increase in productivity in comparison to traditional single-column instruments
• High throughput
• Economical price 
• Full error management so that it can be safely operated without an operator in attendance
• Storage run timers make it easy for users to resume the sample or abort the run
• Compact footprint

Safety features include high and low pressure shut-off, and waste level sensor with shut-off and defined “load” and “inject” positions. A safety timer calculates the minimum time from flow rate and sample loop size for re-switching to load position.

The GPC Quattro instrument has a maximum operating pressure of 1000 psi (70 bar), making it suitable for low and medium pressure GPC columns. The higher pressure capabilities of the GPC Quattro allow it to run stainless steel preparative GPC columns that have shorter run times and to reduce solvent consumption.

During the run, the display will provide complete information including an overview screen that shows the progress of all four runs and screens with more detailed information on the individual columns.

Pickering will be the exclusive North American distributor of this latest GPC instrument from LCTech GmbH.
