- the shape of the coil part 145 can be arbitrarily designed according to Equation 4, so that the mist 212 can be reliably recovered and the reliability of the apparatus is improved. Moreover, since the length of the coil part 145 can be set to the minimum, the apparatus can be reduced in size and cost. Further, since the capture capability of the coil unit 145 can be evaluated by the mist capture evaluation system, the capture mechanism can be inspected and quality guaranteed, and the reliability of the product is improved.

It is desirable to determine the shape of the coil portion so as to reduce the particle diameter.
- the inner diameter D1 of the coil portion contributes the most to the diameter d of the mist, and the smaller the inner diameter, the smaller the mist can be captured. Therefore, the inner diameter of the upstream coil portion 1451 is reduced to the downstream coil.

Further, as shown in FIG. 8, in order to prevent droplets from entering the intake device 143 when the surface treatment liquid is converted into droplets and flows downstream on the downstream side of the coil unit 145 and upstream of the intake device, The waste liquid collector 1471 and the pipe 1422 may be inserted between the pipe 142 and the intake device 143. Alternatively, the connection between the pipe 142 and the intake device 143 may be released and an intake device dedicated to surface treatment may be connected.
- This example has the following effects. Since the surface treatment mist 2122 can be sucked using the suction function of the particle suction and trapping mechanism without disassembling the particle suction and trapping mechanism and the inside of the pipe can be coated, the operation is facilitated. Moreover, even if the coating is peeled off due to maintenance such as cleaning, the coating can be easily performed again. In addition, since the surface treatment liquid is made mist, it adheres to the portion where the sample liquid is likely to accumulate, so that the amount of the surface treatment liquid can be reduced and the processing cost can be reduced.
