The Fox DDC-Sensor™ is a new state-of-the-art sensor technology used in the Fox Model FT1 Thermal Gas Flow Meter. The DDC-Sensor™, a Direct Digitally Controlled sensor, is unlike other thermal flow sensors available on the market. Instead of using traditional analog circuitry, the DDC-Sensor™ is interfaced directly to the FT1 microprocessor for more speed and programmability. The DDC-Sensor™ accurately responds to changes in process variables (gas flow rate, pressure, and temperature) to determine mass flow rate, totalized flow, and temperature.
Static headspace is one of the most popular techniques due to its versatility for analyzing volatile organic compounds (VOCs) in a complex variety of matrices. This is due to the elimination of tedious sample preparation steps and prevents contamination problems that are common to other sample introduction techniques. Teledyne Tekmar draws on our experience as a leader in low-level VOC analysis with the introduction of this companion autosampler to the Headspace product line.
TOC is a popular analytical technique in water quality testing, as seen in many official analytical methods today. The United States Pharmacopoeia (USP), European Pharmacopoeia (EP) and Japanese Pharmacopoeia (JP), recognizes TOC as a required test for purified water and water for injection (WFI). As stated in USP method <643> on Total Organic Carbon:
Ultraviolet (UV) irradiation is used for multifunctional purposes. UV is most commonly used as an environmentally friendly alternative to chemical disinfection. It’s one of the most effective methods for inactivating harmful pathogens such as Listeria, E.coli, Giardia and chlorine tolerant pathogens like Cryptosporidium. UV is also used for removal of organic and inorganic contaminants, including chlorine, ozone and Total Organic Carbon (TOC). UV used in conjunction with an Advanced Oxidation Process (AOP) will remove Compounds of Emerging Concerns (CEC's), Synthetic Organics (SO's), Endocrine Disruptor Compounds (EDC's) and Personal and Pharmaceutical Care Products (PPCP's), as well as various taste and odor compounds from water.
Tekmar’s newest addition to the TOC analyzer product line, the Torch, utilizes a patent Static Pressure Concentration (SPC) for the analysis of TOC/TN using high temperature combustion.
The Aztec 600 Phosphate Analyzer AW636 has been designed specifically for the measurement of phosphate in both potable water and municipal wastewater effluents. It offers reliable and accurate on-line analysis of phosphate up to 50 ppm PO4.
The Forty-X™ disc filter from Evoqua Water Technologies is the ultimate barrier in tertiary filtration. It captures more solids in a smaller footprint with a pleated media design and has evolved to incorporate X-tra's that are important in woven cloth media filtration
Rosemount CT5100 continuous gas analyzer from Emerson is the world’s only hybrid analyzer to combine Tunable Diode Laser (TDL) and Quantum Cascade Laser (QCL) measurement technologies for process gas analysis and emissions monitoring. The CT5100 is available in two variants: a certified system, housed in a purged and pressurized enclosure for hazardous area installations; and a non-certified system for use in nonhazardous areas. Both can house up to six lasers to measure up to 12 critical component gases and potential pollutants simultaneously within a single system - meeting local, state, national, and international regulatory requirements. The CT5100 is a unique combination of advanced technology, high reliability, and rugged design. Its "laser chirp" technique expands gas analysis in both the near- and mid-infrared range, enhancing process insight, improving overall gas analysis sensitivity and selectivity, removing cross interference, and reducing response time. The laser chirp technique produces sharp, well-defined peaks from high resolution spectroscopy that enable specificity of identified components with minimum interference and without filtration, reference cells, or chemometric manipulations.
