The Centri range of products
Centri 90
A platform for high-throughput, routine, high-sensitivity automated analysis using headspace- and SPME- and SPME Arrow-based workflows, with
additional chromatographic performance provided by trap-based
preconcentration.
Along with advanced options for water management, Centri 90 provides
excellent analytical performance across a wide analyte range, and
especially for early-eluting VVOCs.
Conventional GC injection modes remain available, allowing you to
maintain existing workflows while also evaluating the benefits of
preconcentration using the focusing trap.
The platform is Multi-Gas engable, meaning that you can work with your choice of helium, nitrogen or hydrogen carrier gasses to future-proof your laboratory, cost-saving and further productivity enhancements.
Centri 90 has a modular design and is upgradable for thermal
desorption and HiSorb, high-capacity sorptive extraction (Centri 180 configuration).
Centri 180
Featuring all that Centri 90 offers but with extended capability for thermal desorption (from sorbent tubes)
and HiSorb™
high-capacity sorptive extraction, which is provided by a multi-tube
autosampler.
Centri 360
Markes’ award-winning Centri 360 is the ultimate automated multi-mode
extraction and enrichment platform for GC–MS.
Centri 360 is designed for researchers needing comprehensive sample
profiling, and who use multiple sample preparation techniques. Powered by best-in-class robotic automation, Centri 360 gives unrivalled
flexibility for unattended, rapid and efficient extraction and enrichment of
VOCs and SVOCs. With its multiple sampling modes and modular design, Centri
offers maximum versatility for liquid, solid and gaseous samples.
Centri 360 offers the full range of fully-automated sample preparation
techniques (headspace, solid-phase microextraction (SPME), HiSorb™
high-capacity sorptive extraction, and thermal desorption), each with analyte
trapping for sensitivity enhancement. The Centri 360 also offers direct liquid
injection to the GC.
WHY USE CENTRI?
-
Cryogen-free analyte trapping
provides high sensitivity by delivering a sharp, concentrated band of vapour to
the GC.
- The only systems that offer full
automation of sorptive extraction, using inert HiSorb probes.
- Sample splitting and re-collection
allows repeat analysis without the need to repeat extraction steps.
- Multi-step enrichment improves
detection limits and allows:
-
Samples resulting from different
matrix modifications to be combined
- Matrix levels to be reduced by
performing several sequential short extractions, rather than a single long
extraction.
-
Prep-ahead mode and automatic tool
change result in increased productivity.
-
The modular nature of Centri makes
it a futureproof system, enabling analytical capabilities to be easily extended
for greater versatility.
