どの欠点があつた。 In chemical analysis, when analyzing trace components, the contamination of contaminants from the laboratory environment is a problem, and since it generally takes a long time to concentrate a sample solution, the possibility of contamination is particularly high. 2. Description of the Related Art Conventionally, sample concentrators have been proposed as devices that take into account the prevention of contaminants from being mixed into a sample, and which concentrate the sample by evaporating and removing the solvent of the sample solution. A conventional example of this type of device will be explained with reference to FIG. That is, in the conventional apparatus, a concentration container 3 is placed in a closed borosilicate glass container 2 equipped with an inlet 1 for introducing a gas such as nitrogen, and the entire container is placed on a hot plate 4 and heated. However, this device has poor heating efficiency and there is a risk of bumping.
It cannot be heated to such a high temperature that it takes time to concentrate, and
Because it is made of glass, it breaks easily, and because the device cannot be made larger, it is not possible to concentrate multiple samples at the same time.

When 250ml of aqueous solution placed in a 300ml glass beaker was concentrated using a glass heater type hot plate with an output of 200W, the liquid temperature rose to 95℃ within 30 minutes and completely evaporated within 2 hours without bumping. I was able to dry it. In the conventional apparatus, it took 5 hours to evaporate the same amount of aqueous solution to dryness. Therefore, it can be seen that by using the apparatus of the present invention, the concentration time can be reduced to less than half. Furthermore, by flowing nitrogen at an appropriate flow rate into the hood, no clouding or water droplets were generated on the inner surface of the hood.

る。 As described above, the device of the present invention has good thermal efficiency because it heats the concentration container by placing it directly on the ceramic glass heater-type hot plate. However, rapid concentration is possible without the risk of bumping. Contamination can be prevented by covering the hot plate with a heat-resistant hood made of plastic or having a transparent window. In addition, since at least a portion of the hood is transparent, the state of concentration can be observed at all times, and compared to conventional all-glass hoods, there is no fear of breakage, and handling is extremely easy. Moreover,
The front opening/closing type allows for easy loading and unloading of samples. Furthermore, by providing a gas inlet/outlet in the hood and passing clean nitrogen or leaked air into the hood, it is possible to prevent the hood from fogging due to solvent vapor such as water and from adhering to water droplets, thereby increasing the efficiency of concentration. If the device is enlarged and equipped with a large number of magnetic stirrers, a large number of samples can be processed.
