Abstract
(EN)
In this fluid measurement device, first and second valves are connected to first and second parts of a measurement pipeline having a prescribed volume. Each valve of the fluid measurement device has a first and second port that are such that when the valve is closed, the internal volume of the first port is smaller than the internal volume of the second port, and the first ports are connected to the ends of the measurement pipeline. As a result, it is possible to make the amount of sample liquid that enters into the ports of the valves smaller and enhance measurement accuracy. If the fluid measurement device is used as a dilution mechanism, a sample analysis device can be provided that has inexpensive valves, a short operation time, and suppressed dilution precision degradation.
(FR)
L'invention concerne un dispositif de mesure de fluide dans lequel des première et seconde vannes sont reliées à des première et seconde parties d'un pipeline de mesure présentant un volume prescrit. Chaque vanne du dispositif de mesure de fluide possède un premier et un second orifice conçus de telle sorte que lorsque la vanne est fermée, le volume interne du premier orifice est inférieur au volume interne du second orifice, et les premiers orifices sont reliés aux extrémités du pipeline de mesure. Ainsi, il est possible de réduire la quantité de liquide d'échantillon entrant dans les orifices des vannes et d'améliorer la précision de mesure. Si le dispositif de mesure de fluide est utilisé comme mécanisme de dilution, un dispositif d'analyse d'échantillon peut être fourni. Ce dernier possède des vannes peu coûteuses, un temps de fonctionnement court et une dégradation de précision de dilution supprimée.

所定の容積を持った計量管路の第1、第2の部分に第1、第2のバルブが接続される。各バルブは、第1、第2のポートを有し、かつ、バルブが閉じた状態では、第1のポートの内部容積が第2のポートの内部容積よりも小さいバルブであり、第1のポートが計量管路の端部に接続されて、流体計量装置が構成される。これにより、バルブのポート内に入り込む試料液の量をより少なくすることができ、計量の精度が向上する。当該流体計量装置を希釈機構として用いれば、安価なバルブで、作動時間が短く、希釈精度の低下が抑制された試料分析装置が提供される。
