A simple flow injection with flame photometric detection has been developed for determination of sodium, potassium, and total alkalies in portland cement, fly ash, admixtures, and water of concrete. A liquid sample or a digest of solid sample was injected into a water carrier stream which flowed to a flame photometer. A change in emission intensity at a selected wavelength was recorded as a peak. An amplifier circuit was fabricated, which helped improve sensitivity of the flame photometer.

Folegatti et al found that the concentrations of nitrate, potassium, and sodium ions in soil solution and tomato plant sap determined by Cardy ion meters superseded by LAQUAtwin ion pocket meters showed good correlations with those obtained in soil solution and in leaf dry matter, respectively, determined by standard methods in laboratory, and concluded that Cardy ion meters are useful low-cost tools in fertigation management. Plants take nutrients from soil for their growth. Nutrient levels in soil and plant tissues give an indication of the nutrient requirements of crop.

Flame photometry is an atomic emission method for the routine detection of metal salts, principally Na, K, Li, Ca, and Ba. Quantitative analysis of these species is performed by measuring the flame emission of solutions containing the metal salts. Solutions are aspirated into the flame. The hot flame evaporates the solvent, atomizes the metal, and excites a valence electron to an upper state. Light is emitted at characteristic wavelengths for each metal as the electron returns to the ground state.

Determination of Nutrient Concentrations in Soil Solution and Tomato Plant Sap

Typical applications include: Sodium determination in foods, sodium Na and potassium K determination in cement, potassium K in fertilisers, potassium K in plant materials and potassium K in soils, sodium Na in fuels oil. It can also improve throughput, enhance precision and extend the utility of the Model Flame Photometer. Everything is visible on one operational page.

Глаза ее были полны слез. - Прости меня, Дэвид, - прошептала.  - Я… я не могу. Дэвид даже вздрогнул. Он смотрел в ее глаза, надеясь увидеть в них насмешливые искорки.

Беккер застонал и начал выбираться из расписанного краской из баллончиков зала. Он оказался в узком, увешанном зеркалами туннеле, который вел на открытую террасу, уставленную столами и стульями. На террасе тоже было полно панков, но Беккеру она показалась чем-то вроде Шангри-Ла: ночное летнее небо над головой, тихие волны долетающей из зала музыки. Не обращая внимания на устремленные на него любопытные взгляды десятков пар глаз, Беккер шагнул в толпу. Он ослабил узел галстука и рухнул на стул у ближайшего свободного столика.

Стратмор посмотрел на ее залитое слезами лицо, и ему показалось, что вся она засветилась в сиянии дневного света. Ангел, подумал. Ему захотелось увидеть ее глаза, он надеялся найти в них избавление. Но в них была только смерть. Смерть ее веры в. Любовь и честь были забыты. Мечта, которой он жил все эти годы, умерла.

Внезапно он почувствовал страшный упадок сил.

Консьерж шумно выдохнул, словно сбросив с плеч тяжесть. - А-а, Росио - прелестное создание. - Мне нужно немедленно ее увидеть. - Но, сеньор, она занята с клиентом.

Стратмор наморщил лоб и прикусил губу. Мысли его метались. Он, конечно, с легкостью мог набрать код лифта и отправить Сьюзан домой, но она нужна ему .

Убийство. - Да. Убийство азиата сегодня утром. В парке.

Кроме незначительной разницы в атомном весе, они абсолютно идентичны. - Атомный вес! - возбужденно воскликнул Джабба.
