FLEXIBLE, PRECISE, MODULAR

FREESTYLE H53

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.

If comprehensive automation is not required, the unique EluVac™ vacuum manifold is recommended.

EVERYTHING FROM ONE SOURCE

Fully Automatic Clean-up

Glass columns are used in MOH sample preparation to avoid interactions with the analytes or a release of foreign bodies from polypropylene columns.

LCTech offers glass columns in three sizes: 105 mm and 180 mm long glass columns (diameter 17 mm each) are available for standard-compliant use. The time- and cost-saving TINY column was developed for high-throughput laboratories.

The Elufix™ columns from LCTech are filled with 1 g, 2 g, 4 g or 10 g activated Florisil® and 1 g or 2 g anhydrous sodium sulphate. Inert materials such as glass or PTFE eliminate interactions with the analytes, as well as contamination.

The Elufix™ columns can be processed perfectly fully automatically with the FREESTYLE SPE/EVA system. As a result, the user gains a pre-cleaned sample in the GC vial – ready for the analysis.

SYSTEM IN DETAIL

Automated Sample Clean-up

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

1 Sampler Needle Toggle accordion

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

2 SPE Module Toggle accordion

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

3 Glass Column Toggle accordion

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

4 Ready for further processing Toggle accordion

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.
