LEAP Technologies, Inc. was founded in 1989 by three liquid handling automation veterans. Applying liquid handling to chromatography and mass spectroscopy for a variety of labs was the focus. LEAP started as a one-product company representing a fledgling Swiss company, CTC Analytics. GC applications in environmental labs were the main market. LEAP's expertise was integrating its GC autosampler and the headspace sampler into GC and GC–MS systems. Flexibility and portability were the key to selling these very reliable samplers. A second product line was launched that served tablet dissolution applications in pharmaceutical companies. LEAP applied that know-how and launched the Opt-Diss, a unique fiber optic UV system adaptable to all waterbath testers.

Although the majority of solid-phase extraction (SPE) is performed with conventional bonded silica- and polymeric-phases, difficult and complex samples may require more specialized stationary phases. In this instalment of "Sample Preparation Perspectives", columnist Ron Majors discusses advanced topics such as multimodal SPE, restricted-access media, molecular imprinted polymers, immunoaffinity extraction phases and other class-or compound-specific sorbents. These phases provide additional selectivity and procedures using them can be automated. Representative applications will be presented.

Horizon Technology, Inc. was incorporated in July 1992 to develop, manufacture, market, and support an innovative line of automated laboratory products for sample preparation. The initial products automated a new series of solid phase extraction (SPE) methods that have recently been approved by the US EPA. These new SPE methods provide a faster, less expensive, and solvent-reducing alternative to existing sample preparation procedures.

Over seventy years ago, the Laboratory Equipment Corporation introduced the first rapid carbon determinator to the American iron and steel industry. Soon our carbon determinators, resistance furnaces, and sulfur determinators were seen in industrial laboratories across the country, along with the acronym trademark they carried. LECO became synonymous with accurate, dependable instrumentation for the determination of carbon, sulfur, oxygen, nitrogen, and hydrogen in both ferrous and nonferrous industries.
