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

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

LCTech offers ready-filled Elufix™ glass columns (with batch certificate) or glass columns (incl. accessories) for self-filling.

At the end of the SPE step, the sample is filled into a glass and can be removed for manual evaporation, for example.

It is easier with the automated EVAporationsmodule. The sample is concentrated to a desired final volume (e.g. 0.5 mL), then filled into a sealed GC vial and is ready for analysis.
