Cns combustion analyzer

Manufactured by Leco

Sourced in United States

The LECO CNS Combustion Analyzer is a laboratory equipment used for the determination of carbon, nitrogen, and sulfur content in a variety of sample types. It operates by combusting the sample in pure oxygen at high temperatures and analyzing the resulting gases.

Soil pH was determined by a combination of glass electrodes using a 1: 2.5 (w: v) ratio of soil to distilled water (Mi et al., 2018 (link)). Soil total C (TOC) and N (TON) were measured by LECO CNS Combustion Analyzer (LECO, CNS 2000, LECO Corporation, Michigan, United States) following manufacturer protocol. Available phosphorus (AP) in soil was determined by ammonium fluoride extraction (Bray and Kurtz, 1945 (link)). Soil available K⁺, Ca²⁺, and Mg²⁺ were extracted using 1 M KCl (1:10), and determined by using atomic absorption spectrophotometry (NovAA300, Analytik Jena, Germany).

Soil pH was determined by a combination of glass electrodes using a 1: 2.5 (w: v) ratio of soil to distilled water. Soil total C (TOC) and N (TON) were measured by LECO CNS Combustion Analyzer (LECO, CNS 2000, LECO Corporation, Michigan, USA) following manufacturer protocol. Soil microbial biomass C (MBC) and N (MBN) were determined following the fumigation-extraction method. Available phosphorus (AP) was extracted using hydrochloric acid and ammonium fluoride and determined using the molybdenum blue method. The concentration of exchangeable K (Exch. K), Ca (Exch. Ca), Mg (Exch. Mg), and Na (Exch. Na)were tested following hot block acid digestion protocol (Huang, Schulte et al. 1985) .

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
