象試料の分析を行っていた。2. Description of the Related Art At present, global warming has become a major environmental problem. In order to elucidate the material cycle in the ocean, such as carbon dioxide, which is the cause of the problem, and the marine ecosystem, etc. It is imperative to collect a wide range of samples and analyze them immediately on board. In this case, various reagents have conventionally been used for the analysis of seawater and sediment, but it is very difficult at present to mix the reagents onboard a ship such as an observation ship. This is because accurate weight measurement on the ship using an electronic balance or the like cannot be performed due to the motion of the ship. Therefore, conventionally, on a ship, a standard reagent solution corresponding to the reagent was prepared using a reagent prepared in advance on land, and the target sample was analyzed.

However, the efficiency of the standard test solution is short, and the life of the standard test solution is generally short, and it is difficult to store the solution for a long time.

重量の計測ができなかった。A conventional high-precision electronic balance measures weight using a relationship expressed by (mg = F. Formula). Here, m is the weight of the measurement target, g is the gravitational acceleration applied to the measurement target, and the weight m is specified by precisely measuring the force F. Therefore, the condition is that the acceleration a does not fluctuate. However, in a shaking environment such as a ship, the acceleration applied to the measurement object fluctuates due to the vertical movement, and the component of the gravitational acceleration acts on the measurement object due to the tilting of the measuring instrument. The exact weight could not be measured.

Even if it is unknown, the unknown mass m x can be calculated from the relationship m x = (F x / F 0 ) × m 0 .

In addition, the corrector corrects the weight by setting the true value of the gravitational acceleration g to g + a.
Since the electronic balance is always kept horizontal, errors caused by measuring the component force of gravity can be eliminated, and more accurate weight measurement can be performed.

It comprises a sensor for measuring θ and a corrector for correcting the measurement value of the electronic balance. The corrector corrects the weight by setting the true value of the gravitational acceleration g to (g + a) cos θ.

And thus the weight is always less than the true weight (co
(sθ times). On the other hand, according to the configuration of the present invention, the downward acceleration a acting on the electronic balance due to the motion of the ship and the inclination angle θ of the table are measured, and the true value of the gravitational acceleration g is calculated by the corrector to (g + a). ) The true weight can be calculated by correcting the weight as cos θ, and the accurate weight can be measured as long as the force applied to the heavy object can be measured even in a shaking environment such as on a ship. .
