Sensitive Post-Column Derivatization at an Economical Price

The SSI Sensivate represents a new level in post-column performance, size and cost. Based on proven pump technology combined with a unique reactor design and disposable heating blocks, you can now achieve post-column derivatization with great performance at an economical price.

Modular Design

The Sensivate’s modular design means you can choose your pump system, a reactor block (heated) and a second reactor block (ambient) if necessary. Choose reactor block volumes of 0.15 mL, 0.50 mL, 1.40 mL, or order a custom reactor size (see Ordering Information below).

Common Applications

– Carbamates by OPA
– Glyphosates by OPA
– Aflatoxin by iodine
– Amino acids by OPA
– Environmental Analyses: Pesticides, Aflatoxins, Herbacides


– Fast & easy setup: One inlet connection (from column), One outlet connection (to detector)
– Modular: 1 or 2 reactors (1 heated), 1 or 2 pumps
– Proven pump technology with self-flush to improve seal life
– Pulse damper for reduced pulsation
– Reduced number of connections minimizes leaks
– All connections accessible from front panel
– Front panel displays each reagent’s flow, pressure, set, and actual temperature
– Pump flow and reactor temperature settable from front panel or RS232
– Upper/lower pressure and temperature limits, and system shutdown relay
– Modular cartridge reactor, 2 fluid connections, and one hold-down to change volume or reactor
– Disposable reactor cartridges
– Reactor designed to reduce band broadening—not just a coil
– All PEEK fluid path
