MA-1040 – Magnetic Analyzer

The Magnetic Analyzer (MA-1040) is useful for detecting minute quantities of iron in a wide range of materials including high-purity glass used for fiber optics to plastics used in wiring insulation. It can also be used to detect low metallic iron levels in food, precious gems, pharmaceuticals, and many other materials. Detecting low levels of iron in raw materials is critical to the outcome of the final product.

Detect and Measures Low Levels of Metallic Iron Compounds


MA-series Magnetic Analyzers feature sensitivity (down to ~0.00001% magnetic content), The MA-1040 is used to detect very low levels of magnetic iron in food, precious gems, pharmaceuticals, and many other materials. As evidence of its acceptance in industry, the MA-1040 has been referenced in American National Standards Institute (ANSI) and Abrasive Grain Association bulletins.

Particulate Systems’ MA-1040 Magnetic Analyzer incorporates modern electronics and features 0.1 parts-per-million (ppm) resolution, a wide dynamic range, and low power consumption.

Technique Overview:

The MA-1040 Magnetic Analyzer utilizes two matched air core coils, one as a reference, and the other receives the sample material to be analyzed. The coils are energized with an AC source of 683 Hz to reject stray 50 or 60 Hz line frequencies, a potential interference source always present in an industrial environment.
Any imbalance in resonance between the two coils resulting from the presence of magnetic material in the sample will produce a signal of strength proportional to the amount of such material. After synchronous detection, the signal is displayed digitally as percent magnetic content.

Operation is simple and straight-forward. A sample, the weight of which has been entered, is lowered into the center of the sample coil. A digital readout immediately displays the results.
