Atomic absorption spectroscopy
| Oil glossary |
Measures the radiation absorbed by chemically unbound atoms by analyzing the transmitted energy relative to the incident energy at each frequency. the procedure consists of diluting the fluid sample with methyl isobutyl ketone (mibk) and directly aspirating the solution. the actual process of atomization involves reducing the solution to a fine spray, dissolving it, and finally vaporizing it with a flame. the vaporization of the metal particles depends upon their time in the flame, the flame temperature, and the composition of the flame gas. the spectrum occurs because atoms in the vapor state can absorb radiation at certain well-defined characteristic wave lengths. the wave length bands absorbed are very narrow and differ for each element. in addition, the absorption of radiant energy by electronic transitions from ground to excited state is essentially and absolute measure of the number of atoms in the flame and is, therefore, the concentration of the element in a sample.

Aspirating, английский
Atomization, английский
- The conversion of a liquid into a spray of very fine droplets.
- The formation of tiny droplets or a very fine spray, as produced by impinging jets of air on a small stream of paint in spray painting. atomizing-type humidifier a humidifier in which tiny particles of water are introduced into a stream of air.
- Распыление (жидкости)
- Распыление уловителей происходит выброс такой золы из дымовой трубы. ash, total — общая зола. остаток минеральных веществ, полученный в результате сжигания угля при определенных условиях (мос, 2). это определение может быть отнесено и к другим видам топлива. (термин «зольность» неправомерен, поскольку зола образуется только в результате процесса сгорания и по химическому составу отличается от исходных минеральных веществ).
- Распыление (атомизация). в строгом смысле образование атомного пара, т. е. пара, состоящего из свободных атомов данного вещества. распыление играет важную роль в таких методах, например, как аналитическая пламенная спектроскопия. термин распыление (атомизация) также широко используется в качестве синонима другого термина, тоже обозначающего распыление — небулизация (см. nebuli-zation), т. е. образование капельного тумана. 23

- 1. the heat of the body or of the surrounding air, measured in degrees the doctor asked the nurse what the patient’s temperature was. his temperature was slightly above normal. the thermometer showed a temperature of 99°f. to take a patient’s temperature to insert a thermometer in someone’s body to see what his or her body temperature is they took his temperature every four hours. when her temperature was taken this morning, it was normal. 2. illness when your body is hotter than normal he’s in bed with a temperature. her mother says she’s got a temperature, and can’t come to work. comment: the average body temperature is about 37° celsius or 98° fahrenheit. this temperature may vary during the day, and can rise if a person has taken a hot bath or had a hot drink. if the environmental temperature is high, the body has to sweat to reduce the heat gained from the air around it. if the outside temperature is low, the body shivers, because rapid movement of the muscles generates heat. a fever will cause the body temperature to rise sharply, to 40°c (103°f) or more. hypothermia exists when the body temperature falls below about 35°c (95°f).

- A measure of the average kinetic energy of a material. the standard unit of temperature is a kelvin, (k). temperature determines the direction of heat flow between any two systems in thermal contact. heat will always flow from the area of higher temperature (t source) to one of lower temperature (t sink). temperature gradient (?t)
- A measure of the degree of molecular motion of a material compared to a reference point. temperature is measured in degrees farenheit (melting point of ice = 32 º f, boiling point of water = 212 º f) or degrees celsius (melting point of ice = 0 º c, boiling point of water = 100 º c).
- The degree of sensible heat of a body as measured by a thermometer or similar instrument.
- Measure of the intensity of particle motion in degrees celsius (°c) or degrees fahrenheit (°f) or, in the absolute scale, kelvin (k), where the increment of 1 k = 1 °c = 1.8 °f.
- Temperature of surrounding atmosphere. also called dry bulb temperature. compare standard atmospheric conditions. ampere (a): si unit of electric current. ampere per meter (a·m–1): si derived unit of magnetic field intensity. the measurement 1 a·m–1, for example, describes a current of 1 a flowing through a coil that is 1 m in diameter. compare oersted. ampere turn (at): in magnetic particle testing, unit for expressing the magnetomotive force required for magnetization using a coil in terms of the product of the number of coil turns and the current in amperes flowing through the coil. amplitude, echo: in ultrasonic testing, the vertical height of a received signal on an a-scan, measured from base to peak for a video presentation or from peak to peak for a radio frequency presentation.
