The LECO SC632 Series of Elemental Determinators represent the latest generation of LECO horizontal resistance furnace based instruments. 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.
Analysis begins as about 250mg of sample is weighed into a combustion boat, and placed in a pure oxygen environment typically regulated at 1350C. The sample combusts, releasing carbon as CO2 gas with the sulfur forms being oxidized and released as SO2 gas.
Surface Carbon Analyzer SurfaceC-800. The SurfaceC-800 is equipped with a resistance furnace with quartz tube for sample oxidation and can provide temperatures up to 1000 °C. The temperature of the SurfaceC-800 can be set up in steps of 1 °C. As common carrier gas in the SurfaceC-800 oxygen is used.

Feb 14, 2014 · multi EA® 5000 for Micro-Elemental Analysis The multi EA® 5000 is extremely versatile: The determination of carbon, nitrogen, sulfur and chlorine is only a small part of what it can do.
Our popular 928 Series enables you to analyze macro samples with features that streamline your analysis. The latest model to enter our lineup, the CNS928, allows for the simultaneous analysis of carbon, nitrogen, and sulfur from one sample in agronomy and agricultural materials.
For optimal sulfur precision, ceramic crucibles can be pre-baked in a muffle oven at ≥1000°C for a minimum of 1 hour, or tube furnace (LECO TF1/TF-10) at ≥1250°C for a minimum of 15 minutes. The crucibles are removed from the tube furnace/muffle oven, allowed to cool, and are then transferred to a desiccator for storage. Baked crucibles must be
Carbon boil in liquid iron has been studied as a function of some key parameters such as sulfur content (0.005–0.4%) and temperature (1370–1450°C) in a horizontal tube furnace. The metal–gas reactions and their time dependence, that is their dynamic nature, were observed in-situ at the temperature of interest.
The powerful induction furnace of the CS-800 melts all kinds of construction material in a pure oxygen atmosphere at temperatures above 2,000 °C while up to four independent infrared cells with flexible measuring ranges precisely determine the sulfur (and optionally also carbon) content.
The electrodes were then subjected to the SHT process. They were placed into a quartz tube of a horizontal tube furnace, then subjected to slow heating up to 723 K (450 °C) in 2 h, then holding for 10 min and then for furnace cooling (almost in another 2 h).
hood. The resulting product is then carbonized in a horizontal tube furnace under nitrogen at a pressure of .02 MPa at 950 ˚C for one hour. The ramp rate is 10 ˚C/min until 500 ˚C and then is increased to 15 ˚C/min up to the final temperature of 950 ˚C. The sample is then allowed to cool naturally before removing it from the furnace.
N-doped activated conductive carbon (NACC) was prepared by the activated method, according to previous literature.36 Ordi-nary tea was grinded by ball-milling method for two hours, and the powder was pyrolyzed at 350 C for 4 h and at 750 C for 8 h in a horizontal tube furnace with argon to obtain carbonated products.
