  • Supplying High-Purity Gases: Making a Case for In-House Gas Generators (.pdf)
    Selecting the most effective source for high-purity gases is a critical issue for laboratory managers. Zero air and hydrogen are used for gas chromatography with flame ionization detection (GC-FID), and nitrogen is used for high-performance liquid chromatography or gas chromatography with mass

  • Covering Your Tail Gas
    manifold of the oxidizer, flow control or poppet valves, which then directs this gas along with fresh air for combustion into energy-recovery chambers where it is preheated. The process gas and contaminants are progressively heated in the ceramic media beds as they move toward the combustion chamber. Once
  • How to Avoid Gas Line Ruptures
    cylinders to have pressure relief valves or caps installed and maintained in accordance with the organization 's Compressed Gas Association Pamphlets. These small devices are designed to automatically shut off the delivery of gas if the flow exceeds the preset limit. Scott Specialty Gases, a leading
  • New Generation of Premix Gas Blowers (.pdf)
    required for. methane and propane is based on the. volumetric ratio of these fuels with air: Step 3: Determine the volume flow rate. Methane requires 9.53 parts air to 1 part. of excess air in cubic feet per minute. gas and Propane requires 23.82 parts. air to 1 part gas. ft 3. ft 3. The equation
  • Proper Design Essential for Storage, Flow and Metering of Powdered Activated Carbon (.pdf)
    inventory for on-demand. metering using gravimetric or volumetric screw feeders. Uniform flow distribution of PAC from the bin. activator is achieved using the distribution hopper. Each hopper outlet is isolated using automated slide gate. valves. Also, each outlet leg is equipped with a vibrator
  • Throttle Icing: Understanding the Icing Mechanism and Effects of Various Throttle Features (.pdf)
    Some Electronic Throttle Control (ETC) Air Control Valves (ACV) on automotive internal combustion engines are susceptible to icing of the throttle valve. Ice formation can result in an increase in torque required to open or close the valve. Laboratory studies were conducted to improve
  • Medical Device Link .
    delivery, milliliter delivery, and high-force delivery. Swabbable luer valves were developed as substitutes for needle ports in IV applications. The needleless valves allow multiple usage, require no cap, and have good flow and low priming volume. Valve stems and bodies will mate securely. MPMN
  • The Basics of Pressure Regulators
    pressure will decrease to the desired set point as the excess downstream pressure is consumed. A NON-relieving regulator is preferred for use with hazardous, explosive, or expensive gases because no gas is allowed to vent to atmosphere. Now that you have chosen the regulator that best suits your
  • Medical Device Link .
    . Miniature diaphragm pump A miniature diaphragm pump offers free flows up to 35 L/min with a peak pressure of 20 psi. The T2-01 pump offers 12 30-W power consumption over the operating range. Optional multihead configurations are available to achieve free-flow rates in excess of 120 L/min. Several motor
