Teknetics Metal Detectors

Several different kinds of metal detectors exist, I will explain how they work while trying not to get too technical. There are three major classes of metal detectors available.

The first type of metal detector is the PI, which stands for Pulse Induction. Pulse induction means that you are creating an electromagnetic pulse that exits the coil, bounces off a target, then returns to the coil giving a report on the target it hit.

Pulse induction detectors are usually more sensitive to smaller and deeper targets. The down side is they also pick up more trash targets and have a difficult time telling good targets apart from bad targets.

Another detector type is the VLF, which stands for Very Low Frequency. This kind of detector is versatile and commonly used. It uses phase demodulation to discriminate between types of metallic objects like iron and gold. It does a good job at telling the difference between good objects, like gold and treasure, and trash such as nails, bottle caps etc.

Yet another is the BFO, or Beat Frequency Oscillator. The beat frequency oscillator is a low cost circuit design. It has two coils, one at the end of the arm of the detector and one in the control box on the handle. These coils form a pair of tuned oscillators. The oscillators are tuned so that the difference in their frequencies is an exact multiple of each other. The presence of any metallic object will produce a change in either oscillator and thus produce an audible beat frequency harmonic tone.

Each of these technologies has trade-offs, usually between cost and their ability to sense small valuable objects. Newer advances are coming every day. Most of these are in the area of using special digital signal processing of the return signal. Every conductive object has a peculiar signature spectrum that tells a bit more about the object and can also be filtered out to separate junk (iron & aluminum) from Gold Treasure. As technologies advance the price for more capable equipment drops. This in turn opens new depths and more trashy areas to be hunted for treasure.

Please remember to hunt responsibly, avoid trespassing and fill your holes when you are finished. Enjoy hunting for buried treasure!

Flow Analysis with Atomic Spectrometric Detectors $308 Flow Analysis (FA) offers a very convenient and fast approach to enhance and automate 'preliminary steps' of analysis (sample dissolution, pretreatments, preconcentrations, etc.) for atomic spectrometric detectors (ASD). Moreover, flow manifolds can ease the well-known problem of sample introduction/presentation to atomisers or even expand the classical scope of atomic/elemental information, characterizing atomic spectrometry, into the realm of molecules and metal-compounds analysis (e.g. by resorting to coupled separation techniques). All these facts could explain both the extraordinary interest for research and the great importance for practical problem-solving achieved nowadays by FA-ASD. On the threshold of the new millennium when plasma emission and mass spectrometry are so important and popular, the editor considered it timely to produce a book which covers all present atomic detectors and techniques where FA has been or can be advantageously employed. The book has been conceived in three separate parts: Part I gives the fundamental, instrumentation and potential of FIA as a most versatile sample presentation/introduction system for atomic spectrometry. Part II provides a modern account of fundamentals, possibilities and applications offered by flow analysis to atomic spectrometry for on-line sample pretreatments, separations and preconcentrations. Part III deals with applications of FA-ASD combinations to analytical problem-solving in most varied fields and situations. This monograph integrates the most popular aspects of FIA, its new developments for sample on-line treatments and on-line non-chromatographic and chromatographic separations (all typical 'flow analysis') in connection with all branches of analytical atomic spectrometry. Thus, academics, researchers and routine users of analytical atomic spectrometry will find this book invaluable.
