The FREESTYLE GPC is a fully automated chromatographic sample preparation system, that is used for example for clean-up of food, feed and environmental samples. It complies in all areas with the requirements of general methods, e.g. L 00.00-34, EPA 3640A.
Methods are set up for the GPC module via a clearly laid out graphic, as the fundamental clean-up procedure via GPC is pre-defined: forerun, main run (several fractions possible) and tailing. The user only enters the necessary values and can start the system.
The column is firmly connected to the arm, therefore sample and solvent can be dosed precisely and at a constant flow rate via the SPE column with positive pressure using a syringe pump. Drying is also carried out via positive pressure with nitrogen.
Double-walled with two independent lines inside the needle. Spray holes are arranged 360° around the needle:
More than 40 different racks can be freely combined with the FREESTYLE system. Each rack has different sample vessels. Depending on the configuration, up to 180 samples can be processed in a single operation with just one platform. Maximum flexibility for your applications. Just as you need it. Also with temporary racks.
The flexibility of the system also applies to IAC columns. Only one rack type is needed for all columns up to 15 mL. The adaptation is done by adapters. The racks are hooked in with a flick of the wrist and registered in the software with a few mouse clicks.
Fluidics management is a central component of the robotic system, where precise dosing and control of fluids is essential:
The EVAporation module achieves reliable and precise concentration of samples:
The combination of FREESTYLE GPC with the EVAporation module is particularly user-friendly. The selected fraction is collected online in the vacuum chamber and transferred into one or more vials (e.g. GC vials) after concentration. The result is a sample that can be placed directly into the analysis device.
