APCI is a mode of ionization that is similar to ESI [electrospray ionization] in that ionization takes place at atmospheric pressure, entails nebulization and desolvation, and incorporates an interface design, which is similar to that of ESI. A key difference between APCI and ESI is that ESI is based on ions that are formed in solution, whereas APCI uses ions that are formed in the gas phase. In APCI, instead of high voltage being applied to the inlet capillary, mobile phase from the separation device is evaporated within a heater, and the vapor passes a needle with an applied current, which generates a corona discharge for the formation of stable reaction ions.

French

Domaine(s)
  • Physique
  • Chimie analytique
CONT

L'ionisation par APCI [...] se fait grâce à une décharge couronne. Ce type de décharge se forme lorsqu'on applique une haute tension sur une aiguille. Le champ électrique à la pointe de l'aiguille devient alors suffisamment intense qu'il se produit une décharge dans l'air, ionisant ses composantes. Ces ions peuvent ensuite réagir avec les molécules neutres de l'air pour former d'autres ions et même ioniser un analyte gazeux introduit près de la décharge couronne.

CONT

Contrairement à l'ESI [ionisation par électronébulisation], où l'ionisation des molécules s'effectue en solution, l'APCI conduit à la formation d'ions en phase gazeuse.

OBS

APCI : L'abréviation «APCI» provient du terme anglais «atmospheric pressure chemical ionization».

Subject field(s)
  • Anti-pollution Measures
  • Air Pollution
  • Wastewater Treatment
CONT

Venturi scrubbers can be used for removing gaseous pollutants; however, they are not used when removal of gaseous pollutants is the only concern. The high inlet gas velocities in a Venturi scrubber result in a very short contact time between the liquid and gas phases. This short contact time limits gas absorption. However, because Venturis have a relatively open design compared to other scrubbers, they are still very useful for simultaneous gaseous and particulate pollutant removal...

CONT

The system is the part of the physical world that is the object of a thermodynamic calculation. It may be a fixed amount of material inside a tank, a gas compressor with the associated inlet and outlet streams, or an entire chemical plant. Once the system is defined, anything that lies outside the system boundaries belongs to the surroundings. Together system and surroundings constitute the universe. A system can interact with its surroundings by exchanging mass, heat, and work. It is possible to construct the system in such way that some exchanges are allowed while others are not.... If it can exchange heat with the surroundings it is called "diathermal, "otherwise it is called "adiabatic. "

Subject field(s)
  • Milling and Cereal Industries
CONT

Puffed cereal products are prepared by placing the material in pressure cookers or puffing guns.

OBS

The guns, so-called, are pressure vessels about 6 in. in diameter and 30 in. long. They are provided with a steam inlet, a bleed-off valve, and a means for heating the gun-usually by a gas flame. A charge of pellets [made from cereals] at 11 to 12% moisture is dropped into the open end of the gun from a gravity chute leading from the storage bins on the floor above. The end of the gun is sealed by a trip-valve. All valves are closed, sealing the gun. If the gun is heated by gas flames, it is slowly rotated while the temperature, and consequently the pressure, is slowly built up. The temperature may reach 500 to 800 degrees F, and the pressure at the end point may be 100 to 200 psi.... When the pressure reaches the necessary level, the end of the gun is suddenly opened by a trigger mechanism. The contents explode... into a cage or bin with a floor opening leading to a conveyor belt.

DEF

A component of a steam-generating unit that absorbs heat from the products of combustion after they have passed through the steam-generating and superheating sections.

CONT

Heat recovered from the gas is recycled to the furnace by the combustion air and is absorbed in the steam-generating unit, with a resultant gain in overall thermal efficiency... Air heaters frequently are used in conjunction with economizers, because the temperature of the inlet air is less than that of the feedwater to the economizer...

CONT

Air heaters are usually classed as recuperative or regenerative types. Both types depend upon convection transfer of heat from the gas stream to a metal or other solid surface and upon convection transfer of heat from this surface to the air.

Regenerative-type, rotary regenerative, plate-type, tubular air heater.

Subject field(s)
  • Analytical Chemistry
CONT

Dynamic adsorption. The most common mode of adsorptive separation process employs a fixed bed, cyclic operation. As the wet process stream enters the fresh molecular-sieve bed, the water vapor is adsorbed in a finite length of bed called a mass-transfer zone(MTZ), the bed length through which the concentration of the adsorbate is reduced from essentially inlet to outlet conditions. As wet gas continues to flow, the bed may be divided into three distinct zones; the dynamic equilibrium zone with inlet gas, the MTZ, and the remaining active zone. In most molecular-adsorption systems, the MTZ becomes stabilized because of its favorable isotherm and moves at a constant speed. The bed is exhausted when the leading edge of the MTZ reaches the outlet end of the bed. High effective capacity results from high dynamic equilibrium capacity and a short MTZ.

Subject field(s)
  • Analytical Chemistry
CONT

A simple arrangement of two cavities in series showed the feasibility of detecting traces of one gas in another. A klystron was used to generate microwave power which was fed through a wave guide to a transmission-type cavity. Another cavity was mounted in series with and tuned to the same frequency as the first; both cavities were identical except that the second had a gas inlet and outlet ports. From this measuring cell, its microwave energy was sent to a crystal detector. By frequency-modulating the klystron with a 50-cps sine wave voltage on the repeller, a burst of energy passes to the detector each time the generator frequency equals that of the cavities. The detector current is amplified and measured with an oscilloscope. At the beginning of the run, the two cavities are filled with the nitrogen carrier gas and, if the composition in one of the cavities is changed, its electrical size will change... causing a decrease of current from the detector.
