Applied Science BTEC Nationals/Scientific Practical Techniques Amperometry can be used as a detection technique (amperometric titration). The current due to the oxidation or reduction of either the reactants or products at a working electrode will depend on the concentration of that species in solution. The equivalence point can then be detected as a change in the current.

- Flow Cytometry » Flow Cytometry is the technical process that allows for the individual measurements of cell fluorescence and light scattering. This process is performed at rates of thousands of cells per second. » This information can be used to individually sort or separate subpopulations of cells.

Diffractometer The detector end of a simple x-ray diffractometer with an area detector. The direction of the X-rays is indicated with the red arrow. Because it is relatively easy to use electrons or neutrons having wavelengths smaller than a nanometer, electrons and neutrons may be used to study crystal structure in a manner very similar to X-ray diffraction.

What is a Spectrophotometer? A spectrophotometer is one of the scientific instruments commonly found in many research and industrial laboratories. Spectrophotometers are used for research in physics, molecular biology, chemistry, and biochemistry labs.hey measure the absorbance, which is known as the optical density (OD), on a spectrophotometer. One can tell from the OD whether the bacteria are actively dividing or whether they are starting to die. Spectrophotometers use a light source to shine an array of wavelengths through a monochromator.

- Distillation is a process that can be used to separate a pure liquid from a mixture of liquids. It works when the liquids have different boiling points. Distillation is commonly used to separate ethanol-the alcohol in alcoholic drinks-from water.

- A clinometer, also called a declinometer or an inclinometer, is an instrument that measures vertical slope, usually the angle between the ground or the observer and a tall object. A simple, or fixed angle, clinometer requires plenty of room to walk back and forth when measuring object.ilt the clinometer until you can look through the straw or paper tube and see the top of a tall object you want to measure, such as a building. You can use this method to measure the angle between you and the top of that object, or the object's height. 2.

- Found in: Techniques. The condenser aperture diaphragm (or iris diaphragm) is used to control the contrast and resolution of an image. This article explains the usage of the diaphragm. The condenser aperture diaphragm (or iris diaphragm) is used to control the contrast and resolution of an image. This article explains the usage of the diaphragm. An improper setting of the condenser aperture diaphragm (especially at higher magnifications) can be the cause of much frustration both for teachers and students. 1  Students may attempt to find the focus with the condenser aperture diaphragm all the way open. This is difficult if the sample is very thin or weakly stained or the microscope is not equipped with parfocal objectives. Remember, an open condenser aperture diaphragm results in a low depth of field.

- In physics, a spectrometer is an apparatus to measure a spectrum. Generally, a spectrum is a graph that shows intensity as a function of wavelength, of frequency, of energy, of momentum, or of mass.here m and v are mass and velocity of the particle. The focussing principle of the oldest and simplest magnetic spectrometer, the semicircular spectrometer, invented by J. K. Danisz, is shown on the left.

What is a Total Station? Angle Measurements: The electronic theodolite part of total station is used for measuring vertical and horizontal angle. For measurement of horizontal angles any convenient direction may be taken as reference direction. For vertical angle measurement vertical upward (zenith) direction is taken as reference direction.

Estuarine Science The salt content of the water can be measured very precisely using the conductivity method. Salinity can also be measured with a hand held refractometer. A refractometer measures the change of direction or bending of the light as it passes from air to water. Light moves slower in water than air. The more salt in the water, the slower the light moves. You can see the effect of light bending (refracting) as it passes from the water into the air by placing a pencil in a glass of water. The pencil appears to bend where it enters the water.

- Colorimeters. A colorimeter uses a light source of a particular wavelength, a color-changing, colorimetry reagent, and a light detector to determine the concentration of a particular substance, usually in an aqueous or water-based sample. colorimeter is commonly used to test the concentration of disinfectants like chlorine used in drinking water, pool and spa applications, industrial wastewater plants, paper manufacturing, and other industries.

- A turbidimeter is a general term for a meter that measures turbidity. Measuring low level turbidity requires precisely quantifying the scattering of light in water using a turbidimeter that is also a nephelometer. The terms nephelometer and turbidimeter are often used interchangeably, as they are here.

What are the different types of viscometer? What purpose do they serve? Viscometers Viscometers are used to measure viscosity in most circumstances. They work for fluids whose viscosity does not change under varying flow conditions; rheometers must be used when the viscosity does change with flow conditions. Viscomete...
