The Zoex ZX1 modulator is most efficient and versatile technology solution, ideal for use in research and environments that demand elevated flexibility to approach a variety of different applications.
The design uses a fused-silica capillary column coiled in a loop and connected at the extremities to the primary and secondary column, respectively.
A cold jet, cooled by a liquid nitrogen bath, traps the analytes eluting from the primary column whereas a pulsing hot jet re-mobilizes them into the loop for a second refocusing, followed by a very quick transfer as a narrow injection band into the second column.
The periodic switching between collection and re-mobilization takes place for the entire duration of the chromatographic run.
Main application fields:
Petrochemicals, Aroma compounds, Fragrances and perfumes, Metabolomics, Environmental Forensic
Features:
-
2 stage loop modulator
- Can modulate 2 loops in 1 Column Holder: two modulators for the price of one
- Liquid N2 cooling bath (optional 5, 10 or 20 liters)
- Modulation rated for C6+
- Installs on Agilent 8890 e 7890 GC
- Secondary oven installed as an option
- Secondary oven can lead or lag the main oven up to 40°C
- No moving parts
- Modulation cycle range from 1000ms – 32000ms
Benefits:
-
Easy to install; most users can manage own installation within 2 hours
- Can be uninstalled and allow GC to be used for other methods. Not necessary to have dedicated GC
- Sharpest known modulation gives sharpest secondary peaks, hence
- Highest possible secondary peak capacity.
higher sensitivity than non-thermal modulators due to peak focusing
- Compatible with MS at ordinary flow rates, unlike non-thermal modulators.
