Product news

Stop by both 1521 and see the latest innovations from LECO. On display this year will be the TruMac™ N Macro Determinator, perfect for analyzing Nitrogen/Protein samples up to 3 grams in as little as 4 minutes. There will also be Monday afternoon poster session, where the poster Combustion Nitrogen/Protein Determination in Food Matrices Using a Macro Sample Mass, will be presented.

With the TruMac™ N Macro Determinator little or no sample preparation is required for heterogeneous or difficult-to-prepare samples thanks to large, reusable ceramic boats. A horizontal ceramic combustion system using pure oxygen with a maximum temperature of 1450oC ensures the complete oxidation of macro samples. The TruMac also features a 50-position autoloader for the unattended analysis of solid or liquid samples. Ideal for meats, soils, feeds, and starches, the TruMac offers compliance with AOAC, AACC, AOCS, and ASBC methods of analysis.

For more information on the TruMac, be sure to attend the show’s Monday afternoon poster session, where the poster Combustion Nitrogen/Protein Determination in Food Matrices Using a Macro Sample Mass, will be presented by Mason Marsh, LECO’s Organic Product Line Manager.

Additional products featured at the show will include instrumentation for GCxGC, GCxGC-TOFMS, and GC-TOFMS; elemental determination in organic materials; primary analysis of organic constituents such as moisture, gross calorific content, fat, and ash; and elemental determination in metals/inorganic materials.

Gas ChromatographyGas chromatography (GC) is an analytical technique used to separate and quantitate mixtures of small and volatile compounds. Gas chromatographs or GC systems include components such as GC columns, detectors, pumps and autosamplers. Choose from packed or capillary GC columns, flame ionization (FID), photoionization (PID) electron capture detectors and selective or non-selective detectors. Find the best gas chromatographs in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.IncubatorsLaboratory incubators are used to provide a stable environment to cultivate and store samples in, giving you optimal control of temperature, humidity, oxygen and CO<sub>2</sub> levels. Incubators are necessary equipment for cell culture and microbial research. Control temperature with heated or refrigerated incubators, or the levels of CO<sub>2</sub> and oxygen with CO<sub>2</sub> incubators. Using environmental chambers, create a humid climate for testing samples. Find the best incubators in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.MALDI-TOF MSMALDI-TOF mass spectrometers (matrix-assisted laser desorption/ionization time-of-flight) are used for the mass analysis of large molecules, including proteins, DNA, polymers and other macromolecules due to its relatively soft ionization, reducing fragmentation whilst allowing fast data acquisition. Tandem mass analyzers such as TOF/TOF systems can be used to increase resolution and sensitivity of your analysis. Find the best MALDI-TOF products in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Particle CharacterizationParticle characterization instruments are used to determine particle size distribution, shape, surface area, zeta potential, density and porosity of particles and materials. Multiple tecchniques are available for determining particle size, shape and count including dynamic light scattering (DLS), laser diffraction, electrozone (Coulter technique), imaging particle analysis and single particle optical sensing. Determine the density of your material with a gas pycnometer or examine its surface area and porosity with gas adsorption analyzers and mercury porosimeters.
