Parallelisation for High Throughput

GPC uno/quattro

The GPC uno from LCTech is a simple and universal system for gel permeation chromatography for the clean-up of food, feed and environmental samples. The system allows a quick and cost-effective entry into GPC and is very well suited for laboratories with small sample numbers in the basic version. 

With additional modules that can be installed at a later date, the GPC uno can be expanded at any time with further GPC lines and thus adapted to increased sample numbers or different applications.

Expand your system according to your needs:

GPC quattro - Four Systems in One Unit

With the GPC quattro you can use up to four GPC runs in parallel - either with the same method on all columns or with independently defined conditions for each individual column. Each GPC line is operated by its own pump for this purpose. This allows the sample throughput to be quadrupled compared to sequential processing (see following table).

Sequential clean-up

Parallel processing with GPC quattro

45 min. GPC run

45 min. GPC run

+ 5 min. rinse / sample

+ 5 min. rinse / 4 samples

= 11 samples / 9 hours

= 44 samples / 9 hours


Parallelisation up to 4 Columns

Up to four GPC columns can be processed in parallel or independently:

  • Robust: The column cannot burst or shatter thanks to the aluminium casing and thus also protects the user
  • Chemically inert: Contact of the sample only with glass / PTFE or stainless steel
  • All parts solvent resistant
  • Easy readjustment of the column bed
  • No cross-contamination in subsequent samples, even with demanding matrices
  • Suitable for many standard methods (e.g. Extended DFG S19/ ASU L00.00-34)
  • Pressure stable (tested up to 20 bar continuous and 40 bar short term)
  • No cross-contamination in subsequent samples, even with demanding matrices
  • Quality certificate and test chromatogram for each column

The control system - intuitive and clear

The display is equipped with a touch screen. The clear and easy-to-understand standard view provides an overview with all current settings. Already here, each column can be started individually. Operation is intuitive and possible without prior knowledge.

Follow the progress of each column in real time - with time bars, numerical time information and a constantly updated diagram of the flow paths as well as the process status. The alternative: the display on the PC allows you to follow the processes on the system even from remote workstations.
