本発明は炎光光度計に関するもので、安定した炎を得て
、測定精度を向上させることを目的とするものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a flame photometer, and its purpose is to obtain a stable flame and improve measurement accuracy.
臨床検査において、血液中のＮａ量と、Ｋ量との測定は
重要な検査種目であることは周知の如くである。It is well known that the measurement of Na and K levels in blood is an important test item in clinical tests.
上記測定では炎光光度計の炎中で試料を燃焼し、その発
光スペクトルから前記測定がなされる。In the above measurement, a sample is burned in the flame of a flame photometer, and the measurement is performed from the emission spectrum of the sample.
その為に炎は常に安定した状態で燃焼させることが必要
であり、その燃焼状態が炎光光度計の性能を左右してい
た。For this reason, it was necessary for the flame to burn in a stable state at all times, and the combustion state affected the performance of the flame photometer.
しかし、従来の燃焼方法は空気をフィルター等で清浄し
、燃焼部に供給するのみであったために炎の安定状態が
悪く、測定精度を向上させるために発光スペクトルを積
分する必要があり、測定精度は低いものであった。However, in conventional combustion methods, the air is only purified with a filter and then supplied to the combustion section, resulting in poor flame stability.In order to improve measurement accuracy, it is necessary to integrate the emission spectrum. was low.
従って本発明は上述欠点を除去し、安定した炎を得て、
測定精度を向上させることを目的とするものである。Therefore, the present invention eliminates the above-mentioned drawbacks, obtains a stable flame, and
The purpose is to improve measurement accuracy.

図面ととも詳細に説明すると次の通りである。In other words, the sample, air, and fuel are mixed with combustion air supplied through a duct that prevents outside air from entering the combustion section of a flame photometer that burns a sample and analyzes the sample from its emission spectrum. In the flame photometer, the combustion air is supplied from below the flame through a slit in the form of a cylindrical layer around the flame. The embodiments will be described in detail with reference to the drawings as follows.
清浄空気送風機９からの清浄空気は混合用空気管１０で
予混合室５と、燃焼用空気管８で円形のダクト４の空気
室３とにそれぞれ送られる。Clean air from the clean air blower 9 is sent to the premixing chamber 5 through a mixing air pipe 10 and to the air chamber 3 of the circular duct 4 through a combustion air pipe 8, respectively.
円形のダクト４内には空気室３が形成され、該空気室３
にはホヤ１が下方まで挿入され、ダクト４とホヤ１の下
端とで１〜２ｍｍ程度のスリット１１が円形に形成され
る。An air chamber 3 is formed within the circular duct 4, and the air chamber 3
The squirt 1 is inserted all the way to the bottom, and a circular slit 11 of about 1 to 2 mm is formed between the duct 4 and the lower end of the squirt 1.
一方、予混合室５には試料吸引管６からの試料７と、燃
料供給管１２からの燃料とが、前記清浄空気と混合され
、ホヤ１内に挿入されたバーナーより噴出する。On the other hand, in the premixing chamber 5, the sample 7 from the sample suction tube 6 and the fuel from the fuel supply tube 12 are mixed with the clean air and ejected from the burner inserted into the sea squirt 1.
以上の構成において、燃焼用空気はスリット１１の円周
より炎２を中心に円筒型の層状の空気層として供給され
る。In the above configuration, combustion air is supplied from the circumference of the slit 11 as a cylindrical layered air layer around the flame 2.
該円筒型の層状の空気層に四方を支えられた炎２は非常
に安定した炎となり、・その燃焼状態は理想的なものと
なる。The flame 2 supported on all sides by the cylindrical layered air layer becomes a very stable flame, and its combustion condition becomes ideal.
従って以上に述べた如く、簡易な機構により非常に安定
した理想的な炎を得ることができ、測定精度の向上は著
しいものがある。Therefore, as described above, a very stable and ideal flame can be obtained with a simple mechanism, and the measurement accuracy is significantly improved.
又、安定した炎であるため測定系を直流増幅方式とする
ことが可能となり炎光光度計の原価低減にはたす役割は
多大である等、この種光度計において著しい効果を得る
ことができる。In addition, since the flame is stable, it is possible to use a direct current amplification method as the measurement system, which plays a significant role in reducing the cost of the flame photometer, and other remarkable effects can be obtained in this type of photometer.
