Trapping efficiency of capillary cold traps

Journal of Chromatography A, 1988
Abstract The ability to retain a series of n -alkanes (C 3 C 6 and C 12 ) by cryogenic trapping in different types of simple capillary trap has been studied. The traps were either capillary tube packed with glass beads or open-tubular capillary cold traps.

Controlling Reservoir Trap Efficiency

Transactions of the ASAE, 1975
ABSTRACT RESEARCH on three reservoirs in central Missouri has shown that reservoir sedimentation trap efficiency is affected by the detention time of storm runoff and by factors governing sediment particle size. Decreasing the detention time can be done by discharging storm runoff from the reservoir with the use of a bottom-withdrawal spillway.

Avoiding the Efficiency Trap

The Antitrust Bulletin, 2015
For most of the last half century, economic concepts of efficiency have dominated antitrust law and competition policy. Debates have largely centered around how to apply these concepts to specific types of business conduct, for example, whether a particular merger is efficient or a particular action will exclude equally efficient competitors from the ...

Efficient Trapping of HNO by Deoxymyoglobin

Journal of the American Chemical Society, 2004
Nitrosyl hydride, HNO, also commonly termed nitroxyl, is a transient species that has been implicated in the biological activity of nitric oxide, NO. Herein, we report the first generation of a stable HNO-metal complex by direct trapping of free HNO.

Superpositioned dielectrophoresis for enhanced trapping efficiency

ELECTROPHORESIS, 2005
AbstractOne of the major applications for dielectrophoresis is selective trapping and fractionation of particles. If the surrounding medium is of low conductivity, the trapping force is high, but if the conductivity increases, the attraction decreases and may even become negative.

Efficiency of subaquatic light traps

Aquatic Insects, 2017
ABSTRACTSubaquatic light traps are often used for sampling of the aquatic insects; however, their efficiency has not been tested yet. Here, we describe the use of such traps, illustrate the design of a simple trap allowing standardised sampling, and present results of assessment of the light trap efficiency according to the different turbidity levels ...

Efficient cooling and trapping of strontium atoms

Optics Letters, 2003
We report the capture of cold strontium atoms in a magneto-optical trap (MOT) at a rate of 4 x 10(10) atoms/s. The MOT is loaded from an atomic beam decelerated by a Zeeman slower operating with a focused laser beam. The 461-nm laser, used for both cooling and trapping, was generated by sum-frequency mixing in a KTP crystal with diode lasers at 813 nm ...

Production Trap Improvements Using High-Efficiency Internals

Middle East Oil Show, 1995
Abstract Most of the Gas-Oil Separation Plants (GOSP) in Southern Area Producing of Saudi Aramco will be producing between 40% and 75% water cuts by the turn of the century. Many GOSPs will be producing more than twice the amount of water they were originally designed for.

Trapping efficiency of three carnivorous Pinguicula species

Oecologia, 1987
In situ trapping efficiencies of Pinguicula alpina L., P. villosa L., and P. vulgaris L. were compared with each other and with those of artificial traps at a subarctic site in northern Sweden. P. vulgaris had the highest trapping efficiency i.e., 21-37 μg prey trapped cm-2 day-1 and apparently has some means of attracting prey.
