Accessories

System for quantification of the sum of the 4 trihalomethanes species (CHCl3, CHBr3, CHBrCl2, CHBr2Cl) and the dominant species separately, present in drinking water samples configured for online installation in the fully automated water treatment/distribution network. The THM-100 analyzer is based on an extraction and concentration of the analytes by the "purge and trap" (P&T) sampling technique, followed by thermal desorption and spectrophotometric detection of the compounds. The analyzer automatically performs the calibration process.

Quantification range: 5-200 μg / L total THM

Accuracy:

Total THM: ± 10%.

Chloroform: ± 10% Chloroform: ± 10% Chloroform: ± 10% Chloroform: ± 10%

Bromoform: ± 20%.

Repeatability:

Total THM: ± 5%.

Chloroform: ± 5% at 50 μg/L

Bromoform: ± 10% at 50 μg/L

Permissible sample pressure: between 2 and 6 bar

Method of analysis: by purge and trap by thermal desorption with subsequent color generation and colorimetric assay differentiating the different species present in the sample.

Sample volume: 250mL
