The EST Analytical CENTURION Purge and Trap Autosampler is available as a combined system for water/soil samples with or as a system for water samples only.
Unlike many competitors, the CENTURION uses two completely independent pneumatic circuits:
the first for water samples and the second for soil samples.
The aqueous sample is processed directly in the carousel, so the tube is not moved and this eliminates the possibility of “Lost Vial” errors.
The quantity of sample can be dosed either via a fixed volume loop or with an optional syringe, in both cases the speed of the cleaning phases is approximately three times faster than that of competitive products.
The Centurion system also automates the dilution process for samples and standards.
By fully utilizing the potential of this unique feature, a curve in the range 0.05-20 ppb can be automatically created.
The addition of internal standards and surrogates does not use rotary valves and ensures a selection of the amount to be transferred at 1 microliter intervals using only the amount needed without other waste.
Centurion is the only sampler that can be interfaced with two preconcentrators to double the number of samples using a single GC/MSD.
