1.instrument CN628:                                                                                                                            The Dumas principle is an analytical chemistry method to determine the carbon and nitrogen content in samples. The method is based on the combusting of a sample at 1000°C in the presence of oxygen, whereby the carbon and nitrogen are converted to CO2 and NOx respectively. 

2.Instrument FP628:                                                                                               By incorporating state-of-the-art hardware and software technology with key improvements in overall instrument performance and reliability, the FP628 allows you to achieve rapid analysis times of 3.5 minutes for nitrogen/protein results in organic matrices such as foods, forages, fertilizers, and milled products regardless of sample mass.

Part of our popular 628 series, this instrument is also available in carbon/nitrogen and carbon/hydrogen/nitrogen configurations. An optional sulfur add-on module provides independent sulfur determination on macro samples (350 mg).

3.LECO AC-500:                                                                                                                The AC500 determines calorific value, a key indicator of quality and value in solid and liquid fuels, through measurement of the heat released after combustion of a sample. This stand-alone benchtop unit uses a fully-integrated circulation system for a compact footprint—no additional heaters or coolers required. An integral water-measuring station simplifies sample preparation, and a Windows^®-based operating system uses an electronic thermometer accurate to 0.0001°C to measure temperature every six seconds. Two-channel correction is possible through constant temperature monitoring in both the outer jacket and the calorimeter proper.

4. Leco SC632:                                                                                                                  The LECO SC632 Series of Elemental Determinators are specifically designed to determine the sulfur and carbon content in a wide variety of organic materials such as coal, coke, and oils, as well as some inorganic materials such as soil, cement, and limestone.

5.Leco TGA701:                                                                                                                                                                          Thermogravimetric analysis is the basic analysis in many industries to determine material weight loss as a function of temperature in    a controlled environment. To meet the needs of these industries, the TGA701 Thermogravimetric Analyzer was designed for increased    reliability and functionality. Expanded operational controls improve temperature accuracy across the entire range (up to 1000°C),            while a pneumatic carousel assembly improves reliability by eliminating oscillation and increasing position accuracy for automation.      PC-controlled operating software also supports compliance to 21 CFR Part 11 for a closed analytical system.

6.Leco SC844:                                                                                                                                                                                 

Carbon and Sulfur in Inorganic Materials by the Combustion Infrared Detection Technique

LECO combined our customers' feedback with innovative engineering to develop the CS844, an elemental analyzer designed for wide-range measurement of carbon and sulfur content of primary steels, ores, finished metals, ceramics, and other inorganic materials using the combustion technique. 
Our exclusive MS Windows^®-based software, coupled with a boom-mounted touch interface, gives you complete access to instrument control, analysis settings, diagnostics, reporting, and more—without sacrificing valuable bench space.

7.LECO ONH836:

Oxygen/Nitrogen/Hydrogen by Inert Gas Fusion Infrared and Thermal Conductivity Detection

The ONH836 Oxygen/Nitrogen/Hydrogen Elemental Analyzer is designed for wide-range measurement of oxygen, nitrogen, and hydrogen content of inorganic materials, ferrous and nonferrous alloys, and refractory materials using the inert gas fusion technique.
