TOC-L Series Total Organic Carbon Analyzers, TC: 0 to 30,000 mg/L, IC: 0 to 35,000 mg/L, Shimadzu (CAT#: STEM-LE-1192-LC)

TOC-L Series Total Organic Carbon Analyzers use 680°C combustion catalytic oxidation method. These analyzers provide an ultra-wide range of 4 µg/L to 30,000 mg/L, and with NDIR, the detection limit is 4 µg/L. This is the highest detection sensitivity obtainable by the combustion catalytic oxidation method. In addition, the combustion catalytic oxidation method can not only effectively oxidize easily decomposed low molecular weight organic compounds, but also effectively oxidize insoluble and macromolecular organic compounds that are difficult to decompose.

Sample Volume:10 to 2,000 ul (variable)
Measuring Range:TC: 0 to 30,000 mg/L, IC: 0 to 35,000 mg/L
Measurement Mode(s):TC, IC, TOC and NPOC; (POC, TOC via POC + NPOC and TN : Optional)
Oxidation Method:Combustion Catalytic Oxidation Method (Non-Dispersive Infrared detection Method)
Detection Limit:4 or 50 ug/L (TC)
Measuring Time:3 or 4 min
Nitrogen Measurement Range:0 to 10,000 mg/L

Capable of TC, IC, TOC (= TC-IC) and NPOC measurements; options enable POC (volatile organic carbon), TOC through POC + NPOC, and even TN (total nitrogen) measurements
The blank check function evaluates the system blank by measuring the ultrapure water automatically processed in the instrument
Automatic dilution function enables measurement up to 30,000 mg/L
Automatic sample acidification and injection
The automatic dilution function can reduce the salinity, acidity and alkalinity of the sample, thereby greatly extending the use time of the catalyst and combustion tube (the use time depends on the sample and measurement conditions.)
Statistics or priority samples can be added to the analysis plan at any time, even if the autosampler is used without interrupting operation
