Time of travel Dye dilution Infiltration Turbidity Flow

The Field Fluoro-Tec is a versatile and cost-effective instrument designed for the implementation of fluorescence-based techniques in field and factory environments where rugged construction, weather resistance, and battery operation are requirements. Fluoresence techniques offer high sensitivity, wide dynamic range, and selectivity.

Features

Versatility: Designed for large volume flow cells and cuvettes, the Field Fluoro-Tec offers all of the features of our laboratory model with no compromises for field application. Flow cells are available for 6 x 50 mm and 10 x 75 mm tubes. Many other specialty sample holders are available for solids, capillary tubes, and paper strips.

Sensitivity: The Field Fluoro-Tec utilizes a close-coupled, 90 degree excitation and emission measurement configuration. This provides an excellent balance of dynamic range, light throughput, and low stray light. The photomultiplier detector, feedback stabilized amplifiers and power supplies combined with careful attention to thermal considerations provide sensitivity for the most demanding trace analyses.

Stability: Careful system design, feedback stabilized power supplies, and thermal control provide the excellent long term stability that is required for field appplications under variable weather conditions and temperature.

Size: Compact (16 inches W, 10 inches D, 9.5 inches H) and light weight (15 pounds), the Field Fluoro-Tec will fit into any boat, car, or truck. The environmentally sealed anodized aluminum case and console panel provides protection against light rain or spray and against shock and vibration.

Application

Fluorescent Dye Studies including dye delution flow methods, time-of-travel, infiltration, mixing rate, reservoir flushing and residence time.

Chlorophyll in phytoplankton via continuous flow measurements, or in algae extracts via discrete sampling.

Turbidity/Clarity/Particulate Matter studies on-line or via grab samples. Nephelometric (light scatter) measurement can be made in highly colored solutions. Fluorescence measurements can provide accurate results even in turbid samples.

Petroleum Oils (crude oil and some refined oils) in water.
