Within seconds, the Rigaku KT-100S handheld metal analyzer easily performs identification of the most difficult alloy grades. The KT-100S analyzer utilizes laser induced breakdown spectroscopy (LIBS) enabling durable and accurate alloy identification for use in:

Advanced light element identification

LIBS is more sensitive and better suited for light element detection, such as aluminum (Al), magnesium (Mg), and beryllium (Be). However, reliable LIBS’ analysis of materials with these elements has been very limited and typically confined to a laboratory environment – until now. The handheld KT-100S metal analyzer represents recent technological advancements in laser and spectrometer miniaturization that has rapidly expanded the use of this technique into industrial operations. KT-100S offers an advanced method for easily identifying the most popular Al grades – 1100, 6061 and 6063 – as well as Al and silicon (Si) brasses and bronzes or Be in coppers.

In addition to the analytical performance of LIBS technology, KT-100S reduces the need for regulatory licensing and registration that previous generation analyzers were susceptible to.

Durable versatility

The handheld KT-100S LIBS analyzer  delivers accurate identification of popular grades of stainless steel, nickel and titanium alloys, but now with the durability you can count on. The KT-100S metal analyzer has successfully passed rigorous durability tests proving its capabilities in the harshest environments. To guarantee protection, the KT-100S underwent strict testing to the United States Military Standard 810-G. These tests involved rigorous vibration, shock and drop testing to evaluate its durability and performance when exposed to environmental stress. In addition, its IP-54 rating and safety window protect against dusty and wet environments. As the first handheld analyzer to have passed these tests, it is truly optimized for rugged use especially as as a scrap metal analyzer. Thus, KT-100S reduces downtime and costs associated to instrument repair known to be common for traditional handheld metal analyzers.

Sophisticated ergonomics

The design and features of the KT-100S handheld LIBS analyzer put it in a class of its own. The ergonomics consist of a pistol-shape for optimal one-handed operation via use of raised buttons or by use of the ‘quick launch’ navigation buttons located near the trigger. The tilt screen allows for the ability to easily read results in any light and can also be operated as a touchscreen. The KT-100S is also considerably smaller and lighter than traditional metal analyzers. The unique ‘kick stand’ as a ‘grab and go’ position, provides added convenience.

QuickID™ software

Offering a rapid matrix selection, chemical composition and grade identification is simple and easy to read with QuickID software of the KT-100S handheld LIBS. Results are displayed in a simple “match/no match” format that alerts the user of the alloy identification, as well as the elemental composition percentages. Users have the ability to quickly add new alloys to a customized on-board library. The KT-100S is also password-protected with an automatic “sleep mode” for improved safety and battery life. Its on-board camera captures images of the metal pieces being analyzed with the ability to transfer data into a report via USB or WiFi.

Drill Down sample surface preparation

The metal found in these types of industrial environments is usually dirty and oxidized. KT-100S features a patent pending Drill Down auto sample surface preparation capability. Users have the ability to ‘drill down’ dynamically and the analyzer will automatically burn through the common imperfections found in the metal to obtain a clean reading.

CASE STUDY: Sullivan Scrap

As any recycler will report, traditional scrap metal sorting techniques are becoming outdated. At the same time, the volume of scrap received from a variety of sources has increased, fueling the demand for better tools to maximize scrap metal identification and profits. With fluctuating metals prices, precise scrap metal sorting is more important than ever and could mean the difference between reselling materials for cents vs. dollars.

CASE STUDY: The Recycling Center Inc.

The Recycling Center, Inc. is a family owned scrap metal recycling business with five yards located throughout Florida and Georgia. The Recycling Center has been in business for 37 years accepting various kinds of scrap. Annually, they process about 9 million pounds of non-ferrous products - including copper, stainless steel, aluminum, brass, nickel alloys, chrome alloys, and batteries. These materials are typically being received from automobile processing, as well as structural plating.

CASE STUDY: Marine Fasteners

In the 1980s, stainless steel fasteners were sometimes difficult to come by. Except for a few major importers that supplied distributors, inventory was not readily available. Carl Brantley realized stainless steel would never gain widespread acceptance in the US marketplace as long as this system kept the pricing out of reach for the average consumer. His plan – to invest heavily in imported stainless steel and sell directly to the OEM.

White Papers

The most successful and best suited for rapid identification of alloys in field has been Handheld X-Ray Fluorescence (HHXRF). However, the XRF has inherent difficulty in analysis of many important aluminum alloys as well as other alloys containing low atomic number elements such as lithium, beryllium, boron, silicon or magnesium. The common practice to overcome this deficiency has been use of Optical Emission Spectroscopy (OES) or – most recently – Laser Induced Breakdown Spectroscopy (LIBS). Both these techniques can analyze all alloys the XRF can and especially those the XRF cannot. Recent technological advancements made possible design of handheld analyzers based on LIBS which are especially well suited to analysis of aluminum alloys. In this paper we report on the design features of Rigaku’s KT-100S, micro-LIBS handheld analyser and discuss its performance in analysis and sorting of aluminum alloys, especially those containing light alloying elements such as Si, Li, Be, Mg.
