FTIR-Based Analyser Monitors Many Gases at Once

Thermo Fisher Scientific has enhanced its Antaris Industrial Gas System (IGS) to offer faster scan speeds (up to 5Hz at 0.5cm-1 resolution) and extra capabilities to support faster scanning. Based on Thermo Fisher Scientific's Nicolet 6700 Fourier transform interferometer, the Antaris IGS is an FTIR-based analyser capable of monitoring many gases simultaneously, while providing multi-component gas analysis. According to the company, it is highly configurable and used in a wide scope of industrial analyses, particularly in emerging green energy applications, such as landfill methane gas analysis.

The Antaris IGS is also suitable for use in the automotive, chemical and environmental industries. Landfills provide ideal conditions for methanogenesis, with landfill gas comprised of approximately 40-60 per cent methane. Today, significant amounts of waste are decaying under the ground in landfill sites, and methane is produced for years after sites are closed. As this methane escapes, it contributes to global warming. To mitigate this issue, many landfills deploy gas collection systems that not only prevent escape, but also capture contaminant-free gas for use in power generation.

The Antaris IGS is a key part of this process, monitoring landfill methane gas so that it can be reused as a source of green energy. Thermo Fisher Scientific offers pre-calibrated gas analysis methods for the Antaris IGS, allowing users to quickly deploy it without extensive setup and calibration delays.

Operated using the company's Result software, the Antaris IGS provides tools for routine analysis, method development, method transfer, operation setup and data analysis. It offers a choice of detectors, gas cells and other components that enable users to tailor the system to fit a range of gas analysis applications. The Antaris IGS available in both industrial rack-mount and table-top configurations, and can be used as a standalone unit or be incorporated into a larger gas analysis system.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
