Controlled extraction
X-TRACTION supports pressurised fluid extraction with application-specific control of temperature, pressure and solvent composition.
HOME / DIOXINS, FURANS AND PCBs
KATÁLYSIS · LCTECH, A VELARIS BRAND · LATIN AMERICA
Automated sample preparation for dioxins, furans and PCBs.
Extraction, clean-up, fractionation and concentration designed as one traceable analytical chain—from raw sample to defensible evidence.
DESIGN MY WORKFLOW
FROM SAMPLE TO FINAL EXTRACT
The detector cannot repair uncontrolled sample preparation.
Persistent-organic-pollutant analysis depends on decisions made before instrumental determination. Katálysis aligns LCTECH technologies with the matrix, validated method, daily capacity, target fractions and the laboratory's quality requirements.
Automated clean-up
The DEXTech family automates purification and fractionation for PCDD/F, PCBs and other persistent organic pollutants according to the selected method.
Controlled concentration
D-EVA provides parallel concentration with end-point monitoring to protect the defined final working volume.
LCTECH PLATFORMS
Configure the system around matrix, method and throughput.
The final configuration follows the laboratory's intended use, performance requirements and applicable quality controls.
HEATED CLEAN-UP
DEXTech Heat
Designed for matrices whose lipid extracts may solidify at room temperature. Heating supports consistent flow during automated clean-up and fractionation.
15 SAMPLES PER SEQUENCE
DEXTech 16
Sequential unattended processing for laboratories seeking higher capacity, standardisation and operational continuity.
ROBUST ROUTINE
DEXTech Pure
Automated clean-up for multiple dioxin and PCB applications with methods compatible across the DEXTech family.
EVOLUTION · READY-TO-USE
Proprietary columns
Silica, alumina and activated-carbon combinations support specific clean-up stages and fractions, with product-line quality documentation and lot identification.
PRESSURISED FLUID EXTRACTION
X-TRACTION
A modular extraction platform that can reduce open handling and manual transfers within a configured sample-preparation workflow.
SENSOR-CONTROLLED CONCENTRATION
D-EVA
Parallel concentration with automatic stopping at defined volumes for dioxin and PCB fractions, according to the selected configuration.
HALAL · TAYYIB · CHEMICAL SAFETY
Halal-certified laboratory equipment for dioxin sample preparation: what the certificate covers.
Here, this phrase refers only to LCTech GmbH's DEXTech Heat and the proprietary fractionation columns identified in certificate CHAL-INT-2026-74D2 under scheme CHAL-SCH-005.
It does not certify a food product, a laboratory, an analytical method, or any equipment or consumable outside the stated scope. ISO/IEC 17025 accreditation, method validation and applicable quality controls remain separate requirements.
DIOXINS IN HALAL SUPPLY CHAINS CERTIFICATE DETAILS →CURRENT REGULATORY REFERENCES
Use the applicable regulation, matrix and current consolidated text.
Sets maximum levels for certain contaminants in food and repealed Regulation (EC) No 1881/2006.
Sets sampling and analysis methods for dioxins, dioxin-like PCBs and non-dioxin-like PCBs in certain foodstuffs.
A regulatory reference does not replace laboratory validation, competence, accreditation or applicable quality controls.
Before a conformity decision, confirm the current consolidated text, product, matrix, jurisdiction and destination market.
DEFENSIBLE RESULTS
Traceability must cross every preparation stage.
Sample and method
Identify matrix, sample mass, fortification, procedure, method version and acceptance criteria.
Equipment and consumables
Record the system, columns, lots, solvents, standards and processing sequence.
Controls and interventions
Document blanks, recoveries, checks, occurrences, cleaning, maintenance and corrective actions.
Fractions and concentration
Register transfers, fractions, final volumes and concentration conditions to reduce avoidable uncertainty.
Qualification and routine
Align installation, operation, performance checks, training and support with the intended use.
Auditable evidence
A defensible result lets the laboratory reconstruct how each stage was executed and controlled.
Technical questions
Which stages can be automated in dioxin sample preparation?
A configured workflow may combine pressurised fluid extraction, automated clean-up and fractionation, controlled concentration and the validated instrumental determination selected by the laboratory.
What does “Halal-certified laboratory equipment for dioxin sample preparation” mean here?
Here, the phrase refers only to LCTech GmbH's DEXTech Heat and the proprietary fractionation columns identified in certificate CHAL-INT-2026-74D2 under scheme CHAL-SCH-005. It does not certify a food product, a laboratory, an analytical method, or any equipment or consumable outside the stated scope. ISO/IEC 17025 accreditation, method validation and applicable quality controls remain separate requirements.
Is Regulation (EC) No 1881/2006 still the current contaminant-level reference?
No. Regulation (EU) 2023/915 repealed it. Regulation (EU) 2017/644 remains a specific reference for sampling and analysis of dioxins and PCBs in certain foodstuffs.
