so the only variable would be their masses and thus deflection is based on their mass on charge ratio (m/z) ratio. Stage 4: Detection The beam of ions passing through the machine is detected electrically. What the mass spectrometer output looks like The output from the chart recorder is usually simplified into a "stick diagram". This shows the relative current produced by ions of varying mass/charge ratio. The stick diagram for molybdenum looks like this: [pic] You may find diagrams in

Credit card‚ one of the greatest inventions in last century‚ is widely used in nowadays. The first credit card that can pay for different businesses was invented by Frank McNamara and Ralph Schneider‚ the founders of Diners Club‚ in 1950. After a long time development‚ it is believed that credit card is one of the popular tools for payment transaction. According to a research in 2008‚ there were around 80% of United State adult own at less one credit card (Foster‚ Meijer‚ Schuh‚ & Zabek‚ 2010). It

Chapter 3 Practice Problems *(Be sure to put the units in; volts‚ amps‚ etc.) 1.One coulomb of charge passes a point every 20 seconds. Calculate the value of the current through the point. I=Q/t = 1C/20s = .05C/s= .05 A x10^-3 C = 50mA 2.A total charge of 2.5 × 10-3 C passes a point every 40 seconds. Calculate the value of the current through the point. I=Q/t =0.0025C/40s= 6.25 C/s = 6.25 A 4.A total charge of 50 × 10-3 C passes a point every 2.5 seconds. Calculate the value of the current through

Atomic theory is the idea that matter is made up of small particles made of atoms. The atomic theory first had 5 points which were stated by John Dalton who came up with it. The first one was that all elements were made up of small units called atoms. The second one was that all atoms of a given element are identical to each other. Third‚ all the atoms were different from all the other atoms. Fourth‚ atoms of different elements combined together in equal numbers to form compounds. Fifth and final

Gel electrophoresis is a routine laboratory procedure in biochemical studies that takes advantage of a protein’s amphoteric nature to determine its molecular weight and charge by running the sample through a gel matrix under the influence of an electrically charged field. A popular example of gel electrophoresis is Sodium dodecyl sulfate-polyacrylamide electrophoresis or SDS- PAGE which has been used in this experiment to supposedly determine albumin and casein’s molecular weights respectively.

enough space so that a significant number of the nanowires are free to flex within the gaps created by the tips. Moved by the mechanical energy such as waves or vibration‚ the nanowires periodically contact the tips‚ transferring their electrical charges. By capturing the tiny amounts of current produced by hundreds of nanowires kept in motion‚ the generators produce a direct current output in the nano-Ampere range. The Nanogenerator could produce as much as 4 watts per cubic centimeter- based on

more atoms. The bond is caused by the electrostatic force of attraction between opposite charges‚ either between electrons and nuclei‚ or as the result of a dipole attraction. The strength of chemical bonds varies considerably; there are "strong bonds" such as covalent or ionic bonds and "weak bonds" such as dipole–dipole interactions‚ the London dispersion force and hydrogen bonding. Since opposite charges attract via a simple electromagnetic force‚ the negatively charged electrons that are orbiting
