Total Organic Carbon Analyzer

The carbon analyzer is used to analyze total carbon (TC), inorganic carbon (IC), total organic carbon (TOC), purgeable organic carbon (POC), and non-purgeable organic carbon (NPOC) in solid or liquid samples.

The system comprises a Shimadzu TOC-5000A TOC analyzer, a Shimadzu ASI-5000A autosampler, and a Shimdazu SSM-5000A solid sample module. The TOC-5000A has ultralow sensitivity and measures from 4 ppb to 4000 ppm of total carbon and 4 ppb to 5000 ppm of inorganic carbon. This instrument meets the needs of ultrapure industries, research facilities, and high salt requirements of marine users. SSM-5000A Solid Sample Module details follow.

  • Analyte: TC, IC, TOC (= TC - IC)
  • Method: TC: Catalytically aided combustion oxidation at 900°C IC: Pre-acidification, oven temperature 250°C
  • Measuring range: TC: 0.1 mg to 30 mg carbon IC: 0.1 mg to 20 mg carbon

Sample Prep and Options
