What’s next for process analyzers?

April 11, 2007
In this month's installmnet of Product Roundup, we focus on process analyzers and instrumentation that might just help you solve a process problem or two.
The U.S. analytical instrument market is on the move. Advanced technologies, growing linkages between different supporting technologies, advances in various long-standing product development programs, the increasingly competitive marketing environment and the growing demand for high-quality instrumentation are just the tip of the iceberg when talking about the next generation of analytical instruments. In a market fast approaching saturation, vendors have been forced to adapt new technologies to stay competitive. And it has worked.

New opportunities for process analyzers have opened thanks to the imposition of multiple regulations related to safety, environmental issues and quality control in the chemical and petrochemical industries. Many process plants are spending millions on process optimization and advanced process controllers, only to find that at the end of the control loop, a single unreliable online process analyzer can throw away their profit. The market finds this unacceptable.

Tom Griffiths, product manager for analytical instruments at Honeywell Process Solutions, remarked that “responding to user demands, online analyzers are becoming easy to install, easy to set up and easy to use. Users tell us what they want to know and when they want it. Infrared communication tools allow offline configuration, further reducing setup time. New diagnostic tools save time with calibration and maintenance.”

According to a study from www.marketresearch.com, “The technologies that make up the analytical instrument industry are so rich and complex that new types of devices with new capabilities will continue to be invented and commercialized for the foreseeable future; they are just going to keep on coming. It is well recognized by a number of suppliers that a number of novel instruments take years to become established in the marketplace.”

SSV series stream selector system delivers a representative sample from multiple sample streams to a single analyzer. These modular assemblies are ANSI/ISA 76.00.02-compatible and accommodate multiple process streams in a limited amount of space. A double-block and bleed (DBB) module controls each stream  to eliminate cross contamination and maintain sample integrity, Swagelok; 440/349-5934; www.swagelok.com

Industrial FTIR gas analyzers provide real-time, multi-component extractive gas phase analysis for process optimization/control and specialty gas QC applications. AutoQuant Pro software provides quantitative gas phase analysis and simultaneous display of trend charts, IR spectra and concentration tables, as well as fully automated control of sample stream manifolds. MIDAC; 714/546-4322; www.midac.com

Model Xmt two-wire, multivariable liquid analytical transmitter, capable of intelligent Foundation fieldbus communications for liquid analysis, measures pH, conductivity or amperometric measurements, such as dissolved oxygen, chlorine and ozone. It operates with the PlantWeb digital plant architecture when connected to the AMS Suite: Intelligent Device Manager software. A multilingual display is included. Emerson Process Management; 314/533-2000; www.EmersonProcess.com

TS Series hydrogen sulfide gas detectors use an electrochemical cell sensor technology to provide protection against deadly hazards of hydrogen sulfide gas in refining, mining, wastewater treatment, wood-pulp processing and more. They monitor H2S over a 10 ppm to 100 ppm range and can be remotely mounted up to 2000 ft. General Monitors; 949/581-4464; www.generalmonitors.com

PHUCN600 pH, ORP and conductivity controller and transmitter is housed in a NEMA 4X polycarbonate enclosure. It can be powered up for the first time and be programmed for pH, ORP or conductivity metering that can be changed at any time. An LCD display allows calibration, adjustment and troubleshooting. Omega Engineering; 203/359-1660; www.omega.com

Greenline 8000LBH portable mass emissions monitor and combustion gas analyzer simultaneously measures stack gas concentrations, velocity and temperature. The 800LBH takes the measured gas parameters and calculates, records, graphs and reports mass emission in lbs/hour for multiple gases including CO, NO, NO2, true NOX, SO2, CO2 and H2S. E Instruments Group; 215/750-1212; www.einstrumentsgroup.com

MSQ Plus LC/MS detection system offers fully automated system security, secure data integrity, built-in audit trails and electronic signatures and signoffs, enabling 21 CFR Part 11 compliance in drug development and discovery, QA/QC, food and beverage and research laboratories.
