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.
Double-walled with two independent lines inside the needle. Spray holes are arranged 360° around the needle:
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.
LCTech offers ready-filled Elufix™ glass columns (with batch certificate) or glass columns (incl. accessories) for self-filling.
Glass columns for H53-method analysisAt 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.
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.
