Post Column Reaction System. One or two pumps with heated PCR blocks

Sensitive Post-Column Derivatization at an Economical Price

The LabAlliance 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

Features:

• 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

How To Order

To configure the part number for your PCR System:
1. Choose one number from column 1.
2. Choose one number from column 2.
3. If second reactor is required, choose number from column 3.
Examples:
PCR1-R015 = Single Reagent Post Column System with .015 mL heated reactor
PCR2-R050-R050 = Dual Reagent Post Column System with a 0.5 mL heated reactor and a 0.5 mL unheated (ambient) reactor
