The X-ray radiation unit 301a is placed on the front of the body part 311, and includes the X-ray fluorescence detection unit 301b therein. X-ray fluorescence generated by X-rays radiated from the X-ray radiation unit 301a is detected by the X-ray fluorescence detection unit 301b, and thus metal components! and the content of each metal component, extracted through the detection of the X-ray fluorescence, are processed by the signal processing unit 313.
The high-luminance LED 302 is placed below the X-ray radiation unit 301a, and is automatically operated when the illuminance of a surrounding environment, detected by an illuminance sensor (not shown) included in the high-luminance LED 302, is less than 5001x. Here, the high-luminance LED 302 can be manually turned on or off using a switch. The camera 303 is placed on the side of the high-luminance LED 302, and is configured to capture a target using the trigger 305 in a camera mode. The target includes all electronic products (large/small-sized electric home appliances, IT products, communication equipment, lighting apparatuses, electric/electronic instruments, playthings, leisure sports products, medical instruments, kinds of control systems, etc . ) , liquids, soil, fish and shellfish, plants, clothing, etc.

The power unit 307 is mounted below the handle part 309 in the form of a battery, and can be carried so that the metal analysis apparatus can be used anytime and anywhere.
The power unit insert button 308 enables the power unit 307 and the handle part 309 to be easily coupled to each other.
FIG. 4 is a flowchart showing a portable X-ray fluorescence-based metal analysis method according to the present invention.
Referring to FIG. 4, the power of the apparatus is turned on using the control button 312 at step S501.
Then, a metal analysis mode is selected using the control button 312 at step S502.
When the metal analysis mode is selected, the trigger 305 is turned on toward the target at step S503. At this time, unless the apparatus approaches the target within 10 or 20 seconds after the trigger 305 has been turned on, the metal analysis node is terminated. Next, in the state in which the trigger 305 is turned on, the reflective proximity sensor 304 recognizes the target placed in close proximity thereto at step S504. At this time, the reflective proximity sensor 304 senses the target when the distance to the target is equal to or less than 10 mm.
Next, when the reflective proximity sensor 304 senses the target, the X-ray radiation unit 301a radiates an X-ray, thus passing the X-ray through the target at step S505.
Next, X-ray fluorescence, generated from the target by passing the X-ray through the target, is detected, and thus the metal components of the target and the content of each metal component are measured at step S506.
Then, data about the measured metal components and content is displayed on the display unit 306, and is stored in the flash memory 314 at step S508.
Thereafter, when a camera mode is selected using the control button 312, surrounding illuminance is sensed using the illuminance sensor at step S509. In this case, when the illuminance is less than 5001x at step S510, the high-luminance LED 302 is turned on at step S511, thus illuminating the surroundings and capturing the target at step S512. Here, the high-luminance LED 302 performs the flash function of the camera. Further, when the illuminance is equal to or greater than 5001x, it is determined that the surroundings are bright, and thus the camera immediately captures the target. Thereafter, the image captured from the target can be checked on the display unit 306 at step S507, and is stored in the flash memory 314 at step S508.
The display unit 306 of the present invention is implemented as a touch screen type of display, and is configured to select a metal analysis mode or a camera mode.
The metal analysis apparatus according to the present invention is not only used to analyze typical metals, but also is used to analyze, especially, hazardous metal materials (cadmium, lead, mercury, hexavalent chromium, PBB, and PBDE).
Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled iα the art will appreciate that various modifications are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
Thereforβj the scope of the present invention should not be limited to the above-described embodiments, and should be defined by the accompanying claims and equivalents thereof, as well as the claims. [Mode for Invention]
