頼する。When investigating oil-soil contamination, the oil-soil contamination continuous analyzer 100 is carried to the site. Then, the analysis is performed in the following procedure. (1) A cylindrical soil sample is collected by boring. For example, boring to a depth of 8 m at one point, and collecting eight cylindrical soil samples from a first soil sample having a depth range of 0 to 1 m to an eighth soil sample having a depth range of 7 to 8 m. Alternatively, drill at 4 points to a depth of 2m,
A first soil sample having a depth range of 0 to 1 m at the first point and a second soil sample having a depth range of 1 to 2 m have a depth range of 0 at the fourth point.
Collect eight cylindrical soil samples up to a seventh soil sample of ~ 1 m and an eighth soil sample at a depth range of 1-2 m. (2) A cylindrical soil sample is cut in the axial direction to obtain a semi-cylindrical soil sample in order to prevent the spread of oil contamination due to boring from causing a detection error. In practice, half of the cylindrical soil sample may be removed to form a semi-cylindrical shape. (3) The semi-cylindrical soil sample is placed on the sample stage 1.
For example, as shown in FIG. 1, a semi-cylindrical soil sample S
1 to S8 are arranged on the sample table 1 in the order of depth and the order of points. (4) The personal computer 10 controls the motor driving device 20 to drive the motors of the X-direction moving mechanism 5x and the Y-direction moving mechanism 5y, and causes the ultraviolet light 2 and the fluorescent sensor 3 to start scanning the first soil sample (normally). Moves to the first point (the shallow end of the soil sample). (5) The personal computer 10 controls the motor driving device 20 to drive the motor of the X-direction moving mechanism 5x,
And the fluorescent sensor 3 are moved along the longitudinal direction of the soil sample (usually from the shallow end to the deeper end).
At this time, the ultraviolet light 2 is made to blink in a pulse shape, and the detection output of the fluorescent sensor 3 is sampled in synchronization with the blinking. As a result, detection output data at a plurality of points continuous in the depth direction is obtained. (6) When the movement in the longitudinal direction is completed, the motor driving device 2
0 to drive the motors of the X-direction moving mechanism 5x and the Y-direction moving mechanism 5y,
Are moved to the scan start position of the next soil sample (usually, the shallow end of the next soil sample). (7) The above (5) and (6) are repeated, and when the movement in the longitudinal direction with respect to the last soil sample is completed, the movement of the ultraviolet light 2 and the fluorescence sensor 3 is stopped. (8) The personal computer 10 analyzes the detection output data and outputs a sample number having a portion where the fluorescence intensity is larger than a predetermined threshold. (9) The operator sends only the soil sample of the sample number output from the personal computer 10 to the analysis institution, and requests an oil contamination concentration analysis.
