Description

[Detailed description of the invention] Title of invention: Evaporation facility control Background of the invention The present invention provides novel methods such as (a) controlling the evaporation of liquid from chemical samples using dry gas; and (b) a device effective in such a method.

It is often desired to transfer solutes from one lysis system to another. example For example, this means that the initial solution, perhaps a chromatographic process, A portion of the liquid obtained from the solution has a different Liquid chromatography allows for more specific analysis through the use of solvents. Frequently used in fees. Until now, the first solution was put into the tube and then Contact the solution with sufficient drying gas using a gas sparge tube or cannula. It was common practice to remove unnecessary liquid.

In addition, sometimes sensitive solid products may require continuous drying gas passed through the equipment above the maximum drying temperature. damage caused by In addition, the solid content may be somewhat sticky. There are also times when it is desirable to keep it in a moist state. At present, such Dry in stages or schedule drying to prevent sample damage. Reduce the speed to a few minutes, thereby allowing the operator to dry the sample too much. It has been designed to reduce the chances of accidentally doing something for a long time. .

The main objective of the present invention is to ensure that a proper drying of the sample or a proper drying of the evaporation process is achieved. Improvements in the means by which endpoints are obtained have made laboratory evaporation processes more efficient. The objective is to provide a new method for achieving this goal.

It is further an object of the present invention to provide dried samples with predictable resorption or drying properties. The object of the present invention is to provide a new method that can quickly obtain the desired results.

Another object of the invention is to provide an improved method for monitoring the quality of solids produced in medical processes. An object of the present invention is to provide a method and improved apparatus.

Furthermore, it is an object of the present invention to develop a new method for quickly obtaining dried samples with excellent uniformity. The objective is to provide a standard method.

Another object of the invention is to monitor the quality of off-gas from the gas distribution vessel. It is an object of the present invention to provide an improved method and improved apparatus.

Another object of the invention is to remove the incoming dry gas from the gaseous emissions exiting the evaporator. The process involves separating the mouth and thereby making it into a processed container.

Other objectives will be apparent to those skilled in the art from the text.

The above objectives are based on the container of liquid being created and the supply of carrier gas within this container. The gas supply device is equipped with a gas supply device that allows the gas to pass downward through the wall of the container. In order to configure a sample production system that reaches the material to be processed using Therefore, it can be achieved. By this means we leave a fairly free central path within the container. The process gas containing a certain substance is now evaporated through it. It passes upward through the center of the volume surrounded by the walls of the vessel. take out the container The incoming gas mixes with the incoming gas and is not diluted very much, so it can be processed several times. For example, it can be used as the “end point” of the evaporation step. It may be evaluated by temperature. This end point can be measured as an absolute temperature, a temperature difference, or a temperature change. It is important to understand that it is characterized by the rate of change. incoming gas The inlet of the dryer should be far enough away from the material being dried to avoid too much mixing. This allows the vapor of the gas to pass through the material to be dried.

Thus, one feature made convenient by the construction and operation of the parts of the invention described above. An advantageous method of analysis is to remove the escaping gas and to This method uses a collection tube equipped with a thermistor to sense the temperature of the fugas.

Such devices can detect an increase in the temperature of the off-gas to indicate completion or completion of drying. This will notify the control device that the Yes For example, it may be necessary to do things like shut off the drying gas or alert the operator. It is possible to do this.

Another important advantage of the invention is that the gas flow quickly crosses the surface of the liquid being evaporated. An advantageous Uzu Kenpo pattern has been created within the jurisdiction, which is characterized by It remains the same over substantial changes in liquid height.

In one advantageous form of the invention, the container is tubular and provides the incoming gas. It is equipped with a pipe for supplying water. The outlet of this gas supply pipe is located along the inner wall of the pipe. to provide a generally spiral-shaped flow path that eventually reaches the material to be treated. It is located.

In this case, the exiting gas rises and is tied just right to the exhaust manifold. They exit from the central exit.

In practice, a large number of such evaporation devices may share one laboratory location. It is possible that Each device typically includes a drying tube, a closure for the drying tube, and the closing device also connects the inlet gas conduit and the exhaust gas conduit. It is also adapted to form a holding and positioning device. Each drying tube has a thermo A closure member held on a studded stand and having an inlet/outlet tube also has its stand. This means that it can be well positioned in Tando.

The present invention is perhaps most useful in evaporation processes where solid residues are left; It will be seen that there are many other uses of. It sublimates solids from the mixture being processed It can be used very effectively to Such a sublimation process is carried out at a suitable temperature. Inflow gas can be used. It is also an immiscible liquid in the tube It is used very effectively to evaporate the upper layer of the film. Finally, it is short Can be used as a time gas dispersion device.

For example, nitrogen or argon preserves chemical samples before the next step. This is a case where it is used for a short period of time or more. In each case the inlet flow is An important effect is to ensure that it is effectively and reliably introduced into the substance being used.

However, the temperature or temperature at the location of evaporation near the bottom of the drying tube It is also useful to sense the rate of change in degree. This means that inside the pipe buried within the wall of the pipe. This is accomplished by using internal and external sensors. Furthermore, the temperature is Robotics Agemon agazine R, A, Ru5sell's Vo 1, 6, Ib1O [Kajunnetsu Tafti Sensor J Described in the article ``Thermal Touch 5 sensor'') It is sensed by a robot hand that senses the temperature based on the principle of It is. This article is included as a reference.

Also, it should be noted that the post-processing device can be used in conjunction with a robot device, making it especially It is said that it is useful for Robot arm held conduit from storage shelf Used to lift the lid and place it inside the test tube. Furthermore, as mentioned above In other words, the temperature sensitive member is attached directly to the robot's hand with the conduit.
