Automation with the FREESTYLE MOSH/MOAH configuration
- manual method can be easily adapted to FREESTYLE SPE-EVA
- completely automatable
- maximum rack configuration with up to 54 glass columns for SPE-clean-up using FREESTYLE SPE-module
- unattended throughput of 32 samples in 24 hours with the MOSH/MOAH method
- Online EVAporation to a defined final volume followed by filling into closed autosampler vials keeps the samples fresh for the next processing steps
Better than the norm requires (DIN EN 16995:2017 protocol)
Chromatogram MOSH
Chromatogram MOAHFor the official method using on-line LC/GC (FID) analysis, the LOQs for fat-containing matrices did not give reliable data for ≤ 10 mg/kg total sum of MOSH/MOAH.
In order to be able to measure reliably also in the range up to 1mg/kg, in this new method the sample purification was supplemented by a 3 g SPE silica purification step with subsequent evaporation. Interfering compounds should be eliminated (before the epoxidation step specified in the still valid EN 16995:2017). In the end, cleaner chromatograms are obtained due to the resulting reduced need for m-CPBA.
LCTech supports the users with this new step
- ready-to-use silica gel, activated at 400 °C, in aluminium bottle, with batch certificate
- suitable glass columns
- binder-free glass fibre filters to avoid blank values
... and the possibility to fully automate this step with the FREESTYLE SPE-EVA.
It's not just material - with ready-to-use, high quality sorbents and a strong focus on smart and pragmatic handling, this is an LCTech solution that delivers fast, safe and excellent results.
