Leco TruMac CN (Carbon/Nitrogen) Macro Determinator, Model 630-300-900. Series of TruMac macro determinators. Designed to meet your goals when analyzing real macro samples. The TruMac Carbon/Nitrogen Determinator allows you to easily handle characteristically heterogeneous, difficult-to-prepare, or low-content samples. Macro sample sizes (up to 1.5 grams for carbon/nitrogen) are analyzed quickly and simultaneously with low analytical costs. A unique ceramic horizontal oven combined with LECO's carbon/nitrogen determinator design makes the TruMac ideal for a variety of applications including soils, feed, meat, starches, suspensions or wastewater. In addition, the TruMac complies with the analysis methods recognized by AOAC, AACC, AOCS and ASBC. Instrument highlights and functions. Unique ceramic horizontal oven:. The pure oxygen environment ensures complete oxidation of macro samples at maximum temperatures up to 1450 °C. The ceramic lance directs the oxygen stream directly onto the sample. The robust design utilizes six heating elements for increased reliability and efficiency. The rinsing chamber removes the atmospheric inclusions in the samples. Simple and convenient sample handling:. Large, reusable sample boats make handling macro samples easier. Open ceramic boats provide ample surface area for efficient rinsing and combustion of macro-samples. The sample ash remains in the boat for removal after analysis. Nickel foils and/or nickel boats are available for analyzing liquid samples in TruMac nitrogen configurations. Seamlessly integrated automation:. Autoloader for sequential and non-sequential analysis of up to 50 preweighed samples. Robust design for improved reliability and minimal maintenance requirements. Fully automated analysis cycle, freeing the operator to perform other tasks. Improved design and accessibility for combustion gas and aliquot system maintenance:. The carbon/nitrogen configuration utilizes an efficient thermo-electric cooler to remove moisture from the combustion gas, eliminating the need for chemical anhydrone. The ballast allows collection of the aliquot for nitrogen and carbon detection and eliminates the need for full gas analysis. The quick-release ballast assembly and externally mounted pinch valve assembly simplify preventative maintenance routines. The TruMac CN can be used for your most demanding applications. Analyze carbon and nitrogen for your hard-to-prepare environmental and agricultural samples quickly and easily Labprocure is responsible for this device.
