熟練した測定技術者も必要である。(Prior Art) Conventionally, a method for quantifying contaminants in a liquid is to place a liquid containing contaminants into a weighed test tube,
Separate and settle at the bottom of the test tube using a centrifuge, etc., remove the supernatant liquid, measure the weight of the test tube after separation, and calculate the amount of contaminants from the difference between the weight of the test tube alone measured earlier. There is a method to determine this, but this method requires precise weight measurement, and measurement is only possible in a well-equipped laboratory. It also requires skilled measurement technicians to separate and precipitate contaminants and perform more complex sample processing.

The amount of contaminants is determined by precisely weighing the weight of the removed test tube and the weight after removal, which requires precision weighing equipment and a well-trained measurement engineer. It is difficult to easily measure the amount of contaminants in a liquid outside of the designated location.

Place it in a tube and use a centrifuge to separate and precipitate the contaminants in the liquid into a thin part at the tip.The amount of contaminants can be easily detected by the height of the precipitated contaminants. If even greater precision is required, a thin tube section of a detection tube may be inserted between the light emitting sensor and the light receiving sensor to enable detection and measurement of the amount of contaminants based on light transmittance.
(実施例) つぎに、この発明の実施例を図面に基づいて説明する。(Example) Next, embodiments of the present invention will be described based on the drawings.

とによって汚濁物の概略の量を測定することができる。In Fig. 1, the tip C of the detection tube l made of transparent glass or plastic is made thin, and a cap 2 is attached to the tip.
is attached removably, and a scale is provided on the surface of the thin tube section C to indicate the height from the tip. The extract mixed with contaminants is put into the detection tube 1, and the contaminants in the liquid are separated and precipitated by the centrifugal separator 3 in the thin tube portion C of the detection tube 1 as shown in FIG. By reading the height X of the precipitated pollutant, the approximate amount of pollutant can be measured.

でプロットすれば第3図のような図表となる。In addition, when accuracy in measuring the amount of pollutants is required, as shown in FIG.
The thin tube section C of the detection tube 1 is installed between the light emitting section 13 and the light receiving section 14 of the detection device consisting of the light receiving section 14, the calculating section 15, and the display section 16, and each light emitting sensor emits light of equal luminous intensity. The light passes through the precipitated contaminants B in the thin tube portion C of the detection tube I and is received by the light receiving sensors facing each other, and the light transmittance is measured. If the transmittance is plotted in relation to the height X from the end of the tube, a chart like that shown in FIG. 3 will be obtained.

用特性として表示部16に表示する。That is, the light transmittance curve F measured by each light-receiving sensor 12 and the preset judgment reference light transmittance G are compared in the calculation unit 15, and the height Xo of the intersection H is displayed as a substitute characteristic for the amount of pollutant. Displayed in section 16.

意味し、また光通過率曲線Eはこの沈澱密度変化が小で
あることを意味する。Further, in FIG. 3, the degree of rise of the light transmittance curve vAF corresponds to the change in the density of the precipitated contaminant B. In other words, the light transmittance curve E indicates that the contaminants in the liquid have been almost completely separated and precipitated, meaning that the change in precipitate density is large, and the light transmittance curve E indicates that the change in precipitate density is large. means small.
実際の測定においては、この曲線の立上り度合をある範

による測定誤差を少なくすることも可能となる。In actual measurements, by controlling the degree of rise of this curve within a certain range, contaminants are captured in the capillary section C,
Since the degree of precipitation can also be controlled, it is also possible to reduce measurement errors due to differences in the degree of capture.
