Analysis

Sulfur compounds. Agilent Techno-logies, Inc., announces its mass selec-tive detector, which can determinetrace levels of sulfur compounds invarious hydrocarbon matrices withsensitivity in the low parts-per-billionrange. Such sensitivity may interestfuel cell developers involved with re-forming systems. Time-programmedselective ion monitoring allows selec-tive determination of a number of sul-fur components. (Call 650-485-5603,or visit www.agilent.com/chem.)

Hazardous Materials

Infectious waste. DUCAMP is market-ing the DHS System, which uses aunique decontamination process thatrenders infectious waste inert, so thatsuch waste, for example, from hospi-tals, may be placed in a landfill or in-cinerated without further processing.The system also supplies appropriatepackaging for each specific type of ma-terial and a barcode for each containerfor proper tracking.

Measurement

Flowmeter. TTI, Inc., offers Fuji’s TimeDelta S Version 3, which features afully automatic transmission methodand wave pattern selector, which are

advances in clamp-on transit time ul-trasonic flowmeter technology. It canscan through correlation or standardtransit time mode through up toseven transmission patterns and maybe used with ultrapure, moderatelydirty, and aerated systems with pipediameters of 0.5–236 inches (Call 800-235-8367, or e-mail sales@ttiglobal.com.)

Dry or liquid sample testing. EriezMagnetics offers free testing of processmaterials in limited quantities. Testingincludes feeding, conveying, metal de-tection, and magnetic separation.Samples can range from finely milledpowders to large aggregate materialsand liquid suspensions. Ferrous andnonferrous contaminants can be re-moved. (Call 888-300-3743, or e-maileriez@eriez.com.)

Monitoring

Gas detection. Thermo GasTech intro-duces the GT INNOVA, which providesgas detection solutions for industrialand commercial environments. It hasa 20% increase in flow rate; auto-cali-bration; Innova View, a powerful datalog and configuration package; fivecombustible gas ranges; and robustsensors. Detectable gases include ni-trogen oxides, hydrogen cyanide, CO,H2S, ammonia, and phosphine. (Call510-745-8700, or e-mail skubina@thermogastech.com.)

H2S peak readings. MSA announcesits PULSAR Single-Gas Detector,which features peak reading capabili-ty in its hydrogen sulfide (H2S)model. Other models are available forcarbon monoxide or oxygen detectonand have a service life of up to 24months. Uses include industrial envi-ronments, such as chemical, petro-chemical, construction, and utilities.(Call 724-776-8828, or e-mail denise.budzynski@msanet.com.)

Safety

Surge suppressers. Ventronics offersan extensive range of metal oxide varis-tors, gas discharge tubes, and Transorbtransient voltage suppressers, which areamong a large number of high-reliabili-ty surge protection devices now avail-able. These devices provide protectionagainst destructive effects of voltagesurges. Battery packs and assembliesare also available. (Call 908-272-9262,or e-mail ventronics@prodigy.net.)

Treatment

Stormwater discharge. HighlandTank has a line of Highland oil/waterseparators to help satisfy requirementsfor EPA stormwater permits. Theseoil/water separators meet Under-writer’s Laboratories, Inc.’s UL-SU-2215 approval standard and are ratedfor 10-ppm oil and grease, which is re-garded as the national consensus stan-dard. (Call 814-893-1109, or visitwww.highlandtank.com.)

Wastewater pump. Pumpex’s all-newPumpex K-Series wastewater pumpallows municipalities and industrialwastewater processors to gain extend-ed flow output from a smaller, space-saving pump. This electric, submer-sible pump is designed to handle rawsewage, industrial wastewater, andcontaminated or abrasive liquids. Thepump and electric motor are built as asingle unit. (Call 908-730-7004.)

Reverse osmosis. Labconco Corp.offers the WaterPro RO Station forpoint-of-use laboratory-grade reverseosmosis water. Water is produced ondemand and can be dispensed at atypical rate of 1 L/min at inlet water at25 °C. RO-purified water is very usefulfor reagent preparation, general bio-technology work, and glassware clean-ing. (Call 800-821-5525, or visit www.labconco.com.)
