Fatty acid methyl ester (fame) analysis
| Глоссарий по микробиологии и вирусологии
|
Technique in which the microbe’s fatty acids are extracted, converted to volatile methyl esters, and analyzed by gas chromatography, yielding chromatograms that may be compared to reference data for identification purposes

Chromatography, английский
- An analytical technique whereby a complex substance is adsorbed on a solid or liquid substrate and progressively eluted by a flow of a substance (the eluant) in which the components of the substance under investigation are differentially soluble. the eluant can be a liquid or a gas. when the substrate is filter paper and the eluant a liquid, a chromatogram of colored bands can be developed by use of indicators. for gas chromatography, electronic detectors are normally used to indicate passage of the various components from the system.
- A method of separating chemicals through a porous medium, used in analysing compounds and mixtures
- Хроматографии
- Хроматография. аналитический метод, применяемый в основном для разделения компонентов пробы путем их распределения между неподвижной (стационарной) и подвижной (мобильной) фазами.-стационарная фаза мажет быть представлена твердым или жидким веществом или гелем и может иметь,форму колонки, тонкого слоя или пленки; подвижная фаза может представлять собой жидкость или газ. в газовой хроматографии (гх) подвижная фаза —газ, щ стационарная фаза —либо жидкость (газожидкостная хро~` з* 35 `chromium —- хром матография, гжх), либо твёрдое вещество (газоадсорбционная хроматография, гах). газовая хроматография, в частности с; электронозахватным детектором, может применяться для определения` такой группы атмосферных загрязнителей, как углеводороды и некоторые хлорированные углеводороды. хроматография с пламенным ионизационным детектором может применяться для определения окиси углерода. см. также flame ionization analysis — пламенно-ионизационный анализ.
- The generic name of a group of processes for separating and analyzing mixtures of chemical compounds. the separation depends on the redistribution of molecules of the mixture between phases, one of which is thin, often reaching molecular dimensions. for this reason, molecular size and shape are important in the separation, and extremely subtle separations are possible. chute-feed system: pneumatic fiber transport system used in linking textile processing equipment or operations, especially opening, blending, and carding. circular-knit fabric: a tubular weft-knit fabric made of a circular-knitting machine.
- A powerful method for analyzing fluids and determining their components by selective adsorption or size exclusion, using liquid or gas as the eluent. in the adsorptive procedure, the substance flows slowly through a column of adsorbent; as different substances pass at different speeds, they separate from each other and can sometimes be isolated and identified. in other cases, the chromatogram (a trace of the signal from the detector) is utilized to fingerprint a lubricant. liquid chromatography is used for lubricants because of their low volatility. paper chromatography, an adsorptive method, is often used to examine or establish the sludge or dispersive characteristics of a lubricant. gel permeation chromatography, a size exclusion method, separates polymeric (oxidized oil/sludge) material from a lubricant base stock by molecular weight.
Identification, английский
- Identification is the association of a particular record within a set of data with a particular population unit.
- Опознавание
- Идентификация; отбор необходимой информации для обработки; выбор массивов (документы оон)
- The act of discovering or stating who someone is or what something is identification with someone the act of associating with and unconsciously taking on the viewpoints and behaviours of one or more other people
- Идентификация определение, установление возбудителя.
- The correspondence between a largely behavioral model and the portion of reality it claims to represent. one can think of such models as having equations whose parameters must be chosen in order for the model to be specified. a parameter can either be assumed to have a certain value and is then hypothesized or it can be estimated (->estimation) from given data and is then said to be identified. a model may be under-identified when not all of its parameters are identified or it may be over-identified when there are two or more inconsistent estimates of a parameter.
- A unique identifier of an object or person.
- Proof or evidence that supports an identity claim.
- The process of mapping an object onto the supported identification schemas or getting the unique user identifier (uid). the operating system, iis, or commerce server usually provides this identification.
- Установление личности клиента

Matrix assisted laser desorption/ionization time of flight mass spectrometry (maldi-tof), английский
Technique in which the sample (e.g., a microbe colony) is mixed with a special matrix and irradiated with a high-energy laser to generate characteristic gaseous ions that are subjected to mass spectral analysis, yielding mass spectra that may be compared to reference data for identification purposes
Phospholipid-derived fatty acids (plfa) analysis, английский
Technique in which membrane phospholipids are saponified to release the fatty acids of the phospholipids, which can be subjected to fame analysis for identification purposes
