FREESTYLE SPE Mycotoxin

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.

• Non-stop Policy: If a column becomes blocked, the system detects the overpressure. The column is reset, the system cleans itself automatically and continues with the processing of the next column
• One rack for all types of columns: reusable adapters allow easy changing and mixing of columns of any standard format
• Columns can be moved to any position in the rack area
• Three solvents as standard, upgrade option up to six or even fifteen solvents

Fluidics management is a central component of the robotic system, where precise dosing and control of fluids is essential:

• 10 mL syringe pump for an exact way to dispense solutions and samples in defined quantities with defined flow rates
• 6 freely selectable ports for solvent supply. (Optional upgrade for 15 freely selectable solvents possible)
• N2 valve for drying or evaporation process
• Chemically inert PTFE sample loop for cross-contamination-free work

Double-walled with two independent lines inside the needle. Spray holes are arranged 360° around the needle:

• Spraying solvent into a vial (e.g. for quantitative transfer) or into the vacuum chamber for rinsing and/or cleaning
• Filling into vials closed with septa (e.g. 1 mL vial with insert)
• Sharp tip for piercing a septum without punching out parts of the septum

In the washing device, the double-walled needle is cleaned from the inside and outside. This further ensures cross-contamination-free working.

If immunoaffinity columns dry out, this considerably impairs their effectiveness. The FREESTYLE system solves this problem by leaving the columns on the rack with the storage buffer and lid closed, and only pushing the lid through the SPE gripper at the time of use. The mechanics of the robotic system enable the processing of all common standard formats of IAC columns and ensure that they remain fresh and ready for use.

More than 40 different racks (also temperature-controlled) can be freely combined with the FREESTYLE system.

Maximum flexibility for your applications, just as you need it, also for IAC columns. Only one rack type is needed for all columns in standard formats up to 15 mL. Adaptation is done by adapters. The racks are hooked in easily and transferred to the software with just a few mouse clicks.

A direct, automated elution of the SPE column, directly into the EVAporation chamber within one method (online), is particularly convenient. An optional liquid/liquid solvent exchange completes the automation.
