摘要： A system and method for spectrophotometrically measuring the total alkalinity of a liquid sample. In a particular aspect, the method involves equilibration of a CO2 gas with a sample solution across the permeable walls of a Teflon AF 2400 liquid core waveguide. The waveguide acts as both an equilibration membrane and an optical cell in which spectrophotometric pH measurements are obtained via measurements of absorbance ratios.

摘要： Automated in-situ instrumentation has been developed for sensitive, precise and accurate measurements of a variety of analytes in natural waters. In this work we describe the use of ‘SEAS’ (Spectrophotometric Elemental Analysis System) instrumentation for measurements of solution pH. SEAS-pH incorporates a CCD-based spectrophotometer, an incandescent light source, and dual pumps for mixing natural water samples with a sulfonephthalein indicator. The SEAS-pH optical cell consists of either a liquid core waveguide (LCW, Teflon AF 2400) or custom-made PEEK tubing. Long optical pathlengths allow use of indicators at low concentrations, thereby precluding indicator-induced pH perturbations. Laboratory experiments show that pH measurements obtained using LCW and PEEK optical cells are indistinguishable from measurements obtained using conventional spectrophotometric cells and high-performance spectrophotometers. Deployments in the Equatorial Pacific and the Gulf of Mexico demonstrate that the SEAS-pH instrument is capable of obtaining vertical pH profiles with high spatial resolution. SEAS-pH deployments at a fixed river-site (Hillsborough River, Fla.) demonstrate the capability of SEAS for observations of diel pH cycles with high temporal resolution. The in-situ precision of SEAS-pH is better than 0.002 pH units, and the system's measurement frequency is approximately 0.5 Hz. This work indicates that in-situ instrumentation can be used to provide unique capabilities for observations of carbon-system transformations in the natural environment.

摘要： A liquid core waveguide for fluorescence spectroscopy is provided. According to one version of the present invention, a substantially cylindrical support tube is provided, having a substantially constant outer diameter, and a flexible tube is wrapped in contiguous windings about the outer surface of the support tube to form a tight coil about the support tube which is configured of material that is transmissive of light in the relatively short wavelength range which is used to excite the molecular material in the flexible tube. This feature enables the flexible tube to be wound tightly about the support tube without crimping (thereby to form the liquid core waveguide into a compact package), and enables light in the relatively short excitation range to be effectively transmitted through the support tube and into the flexible tube.
