Leco USA

The one thing all laboratories need to be successful is results they feel confident in. Since 1936, millions of samples worldwide have been analyzed using LECO instruments for elemental analysis, thermal analysis, metallography, and mass spectrometry. LECO comprehensive solutions for improving productivity include working  to find the right equipment for the type of analysis you are doing — and providing with the training, application support, and service you need to keep your lab running at its best.

Bomb Calorimeter

The calorific value is a type of a parameter used for measuring the quality of the solid fuels. It is determined by a precise measurement of heat released in the combustion process in a strictly controlled environment. The heat released is in proportion with the calorific value of the fuel.

The LECO AC600 isoperebol semi-automatic calorimeter is ideal for measuring the calorific value of various fuels. It operates on a semi-automatic principle and it uses the TruSpeed thermodynamic. This provides analysis that is absolutely precise.

It has a new ergonomic design, integrated vessel, charging device and a very light combustion vessel and a Windows-based OS which allows setting of all test parameters. It finishes the analysis in only 5.5 min.

Thermogravimetric Analyzer

The TGA maintains the core capabilities and reliability of previous generations of LECO macro TGA instruments, while providing key improvements in performance and robustness. State-of-the-art hardware combined with a touch-screen software platform and rugged design provides accurate, high-precision thermogravimetric constituent analysis—moisture, ash, volatile content, and LOI in various organic, inorganic, and synthetic materials. Complying with ASTM standardized methods, the TGA is applicable to many industries and applications including coal, cement, catalyst, foods, and feeds.

Macro thermogravimetric analysis (nominal 1 g) replaces the often slow, labor-intensive, traditional manual gravimetric techniques that require multiple sample weighing and transfer steps involving ovens, muffle furnaces, and desiccator equipment. Flexible method settings, automation, and hardware capabilities deliver an automated analysis process while requiring only the manual measurement of the initial sample mass, for maximum productivity in your lab.

Cornerstone Mobile remote software keeps the user updated from their smartphone, tablet, or PC on the instrument’s analysis batch progress, performance, and status while away from the instrument.

Sulfur and Carbon Analyzer

Easily analyze your wide-range carbon and sulfur content with our  for the determination of carbon and sulfur in primary steels, ores, finished metals, ceramics, and other inorganic materials using the combustion technique. State-of-the-art hardware and our exclusive Cornerstone® touch-screen software platform provide your laboratory with increased usability and a lower cost-per-analysis.

Macro and Micro CHN/S/O Analyzers

The  Micro delivers optimal performance in carbon, hydrogen, nitrogen, sulfur, and oxygen determination in solid or liquid micro samples. Components work together to provide you with reliable, consistent performance marked by rapid analysis times, greater robustness/less downtime, and reduced maintenance.

Mercury Analyzer

LECO’s  Mercury Analyzer is specifically designed for the fast, safe, and accurate determination of trace mercury in various liquid and solid samples. Using direct combustion, this unique system easily analyzes samples in as little as 5 minutes, with no sample pretreatment or concentration spikes—saving you valuable time!

Ash Fusion

Assays involving radiochemicals can be run in various medium- and high-throughput plate-based formats, including filtration assays (commonly used for thymidine incorporation and radioligand binding assays), liquid scintillation counting assays, scintillant coated-plate assays (commonly used for HPLC fraction analysis or 51Cr release assays), and proximity assays (using SPA beads, FlashPlate® microplates, or Cytostar-T™ plates). Plate recommendations for each assay format are detailed in the sections below. Radiometric assays that measure signal coming from a beta-emitting radioisotope (such as 3H, 14C, 32P, 33P, and 35S) or a radioisotope that releases Auger electrons (such as 125I and 51Cr) typically rely on addition of a scintillant, which captures the energy from the emitted beta particle and, in turn, releases energy in the form of photons that can be measured on radiometric instruments (such as the PerkinElmer MicroBeta® or TopCount® Plate Counters) that use a photomultiplier tube for detection. Because of this, plate selection for these assays will factor in some of the same considerations as for standard luminescence assays. Liquid scintillation counting assays require the use of liquid scintillation cocktails, which can sometimes contain harsh organic solvents. For these assays, compatibility of the plate material with the cocktail solvent should be a consideration. Additional considerations such as whether the detection instrument is reading from the top and/or bottom of the plate should also be factored in when choosing a plate. Clear-bottom plates allow for bottom-reading and coincidence measurements on instruments such as the MicroBeta plate counter. Clear-bottom plates with black or white wells can be used in conjunction with BackSeal™ Adhesive Bottom Seal to reduce cross-talk in top-reading measurements. Solid opaque plates need to be measured with top-reading instruments, such as the TopCount system (the MicroBeta counter can also support top-reading measurements).

GC x GC Two Dimensional GC,GC xGC TOF.

LECO GCxGC combined with Electron Capture or Flame Ionization Detectors offer you the resolving power of a GCxGC system combined with our advanced ChromaTOF® software for an increase in efficiency and productivity for samples that are too complex for a single-channel detector system. Ideal for everyday quality control and production needs, these GCxGC systems provide you with all the tools necessary to achieve exceptional results in a cost-effective package.
