LCTech offers the complete solution for standard-compliant processing of the hydrocarbon oil index. Both filled columns and empty columns for self-filling with suitable binding agent-free filters are available.

In combination with the FREESTYLE SPE/EVA for automation, the cleaned-up sample, perfectly filled into the GC vial, is available for analysis. 


    Automated Sample Clean-up

    1 Sampler Needle
    2 SPE Module
    3 Glass Column
    4 Ready for further processing

    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.

    Glass columns for H53-method analysis

    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.

    H53 Rack

    The robotic system has two z axes. Each moves independently of the other. The needle aspirates the sample in the sample loop and releases it into a second container via the SPE column. A typical configuration for sample preparation to determine the hydrocarbon oil index according to DIN EN ISO 9377:2-2000.
