LECO CORPORATION SOME COMPANY FACTS

SOME COMPANY FACTS LECO CORPORATION Established in 1936 by Carl Schultz, the Laboratory Equipment Company introduced what would be the first rapid carbon determinator to the American iron and steel industry. Today, over 80 years later, LECO continues to be a family-owned company in its third generation of leadership and is recognised globally as a leader in the development of high-quality elemental and thermal analysis equipment, mass spectrometers and chromatographs, metallography and optical equipment, and consumables. Our headquarters in St. Joseph, Michigan, USA, is comprised of several facilities...

Energy & Fuels While LECO has continued to be a leader in carbon/sulfur testing of coal and coke, it has since expanded into biofuels, biomass, oil additives, petroleum products. Ensuring existing sources, and analysing fuels of the future – LECO technology is here to validate their potential and quality. Environment & Agriculture LECO instruments helps to monitor environmental impact, manage agricultural resources more efficiently by monitoring composition of arable soils, crop and fertilisers; determining optimum nutrition values for animal feed. Food Safety Multi residue methods and screening...

BENEFITS OF GC×GC Comprehensive two-dimensional gas chromatography (GC×GC) is an analytical technique that has been around for over 25 years. GC×GC increases separation capacity by using two separate columns with orthogonal selectivity connected in series through a modulator (Figure 1). The modulator rapidly traps and "injects" the effluent from the first dimension column onto the second dimension. Figure 1: Principle of GC×GC The result of a GC×GC analysis is a chromatographic plane (contour plot) (Figure 2), that depicts the separation over the nonpolar and polar columns. The chromatographic...

BENEFITS OF TIME-OF-FLIGHT MASS SPECTROMETRY A time-of-ight mass spectrometer (TOFMS) for gas chromatography (GC) (Figure 3) is the right choice for complex samples, targeted and non-targeted analysis and fast GC or GC×GC. Time-of-flight mass spectrometry (TOF-MS) is probably the simplest method of mass measurement to conceptualise. The ion’s mass-to-charge ratio is determined via a time measurement (Figure). The ability to collect a full mass range without sacricing data acquisition speed or sensitivity is perfectly suited for non-targeted analyses. Using a non-targeted approach is benecial...

SPECIFIC LECO GC-TOFMS INSTRUMENT FEATURES

STAY CLEAN® ION SOURCE STABILITY Fouled ion sources and related issues are often time consuming to diagnosis and resolve. A definitive diagnosis can only be achieved after other preventative maintenance steps (inlet maintenance, column trimming, etc.) have been tried and tested. Once the source has been pinpointed as the issue, users have to clean the source before proceeding. Even routine, scheduled preventative cleaning leads to system downtime In less controlled environments the incremental contamination of an ion source may not be noticed until long past the point of compromised results or...

LECO MODULATOR PORTFOLIO GC×GC offers dramatic improvements over traditional GC for the analysis of complex mixtures. This is due to significantly increased chromatographic resolution. The modulator, considered the heart of the GC×GC system, is a device which injects the effluent from the primary column to the secondary column. There are two primary forms of modulators in GC×GC; thermal- and ow-based. These techniques are described in general terms, but with focus on ow modulation. Thermal-based modulators (Figure 6) rely on a cooling mechanism to trap eluent from the rst column, followed by...

FFP ® FOLDED FLIGHT PATH ® LECO’s patented Folded Flight Path® (FFP®) technology is celebrating ten years of mass spectrometry breakthroughs. This ingenious concept uses multi-reflecting technology to strip away the oversized flight tubes from traditional high resolution Time-of-Flight (TOF) mass spectrometers and packs an impressive resolving power of 25,000 into a surprisingly small footprint. Ultra High Resolution mode enables the FFP instruments to reach resolving powers of over 50,000 with flight paths equivalent of 40 m without a single increase in lab space. The ingenious design of the...
