Orbitrap. In mass spectrometry, Orbitrap is an ion trap mass analyzer consisting of an outer barrel-like electrode and a coaxial inner spindle-like electrode that traps ions in an orbital motion around the spindle. [1] [2] The image current from the trapped ions is detected and converted to a mass spectrum by first using the Fourier transform ...
The M44 cyanide device (also called a cyanide gun, cyanide trap, or canid pest ejector) is used to kill coyotes, feral dogs, and foxes. It is made from four parts: a capsule holder wrapped with cloth or other soft material, a small plastic capsule containing 0.88 grams of sodium cyanide, a spring-powered ejector, and a 5–7 inches (130–180 ...
Rocket nets and cannon nets are types of animal traps used to trap many live animals, usually birds, but they also have been used to catch large animals such as various species of deer. Rocket nets, cannon nets, and other net launching devices are built upon similar principles have been used since the 1950s (Dill and Thornsberry 1950, Hawkins ...
In the Ghostbusters universe A replica of the ghost trap used in the original film. The proton pack, designed and built by Dr. Egon Spengler, is a man-portable cyclotron system (and indeed Dr. Peter Venkman refers to the proton packs in one scene as "unlicensed nuclear accelerators"), that is used to create a charged particle beam—composed of protons—that is fired by the particle thrower ...
Pheromone trap. A pheromone trap is a type of insect trap that uses pheromones to lure insects. Sex pheromones and aggregating pheromones are the most common types used. A pheromone-impregnated lure is encased in a conventional trap such as a bottle trap, Delta trap, water-pan trap, or funnel trap. Pheromone traps are used both to count insect ...
Hydrodynamic trapping allows isolation of a target cell from an aqueous mixture. Several advantages exist for the use of hydrodynamic trapping as a separation technique, including: higher processing rates, less use of samples, better spatial resolution, and cost efficiency. The way target cells are separated in a solution depends on several ...
The average cost of a gallon of regular gas was $3.44 on Wednesday, according to AAA, down about 4% from one month ago. Prices are expected to fall further as a result of lackluster demand as ...
Petroleum trap. In petroleum geology, a trap is a geological structure affecting the reservoir rock and caprock of a petroleum system allowing the accumulation of hydrocarbons in a reservoir. Traps can be of two types: stratigraphic or structural. Structural traps are the most important type of trap as they represent the majority of the world's ...
