Ultra-sensitive Microliter UV/Vis Spectroscopy with 2 to 500 cm optical pathlength! Mote Marine Laboratories in Sarasota, Florida has partnered with WPI, using the Company’s waveguide technology. WPI customized the LWCC installed in the instrument package inside these AUV’s (Autonomous Underwater Vehicles). The LWCCs are used to monitor the color of seawater in the Gulf of Mexico. One of the primary interest areas of this research is red tide algae blooms. Further, modular spectrophotometric sample systems can be assembled using a TIDAS E spectrometer and a UV/VIS light source such as D4H and FO-6000 (see pages 198-199). Applications LWCCs have been used in a variety of applications, such as liquid chromatography, stopped-flow and colormetric detection, drinking water analysis, as well as environmental and oceanographic monitoring systems (see References on www.wpiinc.com). WPI’s Liquid Waveguide Capillary Cells are made of fused silica tubing with an outer coating of a low refractive index polymer. This results in high signal stability and easy removal of air bubbles trapped in the sensor cell due to the hydrophilic character of the cell wall. SPECTROSCOPY Waveguide Cleaning Kit (#501609), above, includes the most commonly needed cleaning solutions for the LWCC waveguides. The LWCC Start-up Kit (#KITLWCC), at right, includes two fiber optic cables (#FO-600-SMA1M), Sample Injector Assembly (#58006), MiniStar™ Peristaltic Pump, and WaveGuide Cleaning Kit (#501609). LWCC injection System For flow analysis, including simple fluid injection analysis (FIA) setups, add WPI’s LWCC injection system (WPI #89372). A selection valve provides baseline or cleaning solutions to the sample stream. The injection valve injects a sample into the stream, avoiding the introduction of air bubbles or changes of flow rate. LWCC-3050 LWCC-3100 LWCC-3250 LWCC-3500 Liquid Waveguide Capillary Cell, pathlength = 50 cm Liquid Waveguide Capillary Cell, pathlength = 100 cm Liquid Waveguide Capillary Cell, pathlength = 250 cm Liquid Waveguide Capillary Cell, pathlength = 500 cm ACCESSORiES A sample injector assembly can be used to conveniently fill an LWCC with sample solution using a peristaltic pump. Please note that the LWCC requires two optical fibers to connect to spectrophotometer system. Choose between anti-solarized 400 micron core or UV-enhanced cables (may be ordered in 1 or 3 meter lengths). * Related Patents Micro Chemical Analysis Employing Flow Through Detectors, 1995, U.S. Patent No. 5,444,807.
