  • Page 32: Principle Of Operation

    Technical description Principle of operation The analyzer multi N/C pharma HT is a compact and powerful device to determine the total carbon content and/or total nitrogen content in aqueous samples. Fig. 19 Principle of operation The digestion is performed in the multi N/C pharma HT by thermocatalytic high-temperature oxidation in the presence of special catalysts.

  • Page 33: Measuring Method

    Technical description Inorganic carbon is detected by injecting a sample aliquot into the acidic TIC reactor and driving out the formed CO via the NDIR detector. The CO or NO concentration is detected several times every second. An integer over time is calculated from this signal sequence.

  • Page 34: Tic Analysis

    Technical description The TOC analysis should be used when the sample contains easily purgeable organic sub- stances as benzene, cyclohexane, chloroform, etc. The TOC analysis should not be used when the TIC content of the sample is significantly higher than the TOC content. Parallel to the TOC detection the TN detection is possible.

  • Page 35: Tn B -Analysis

    Technical description 4.3.6 -Analysis Parallel to all analyses via high temperature incineration, the detection of the total bound nitrogen is possible in the TN analysis. The thermocatalytic oxidation results in nitrogen oxides which can be detected alternatively using an external Chemiluminescence detector (CLD).

  • Page 36: 4.5.1.3 Multiple Point Calibration With Constant Sample Volume

    Technical description For measurements in the range of low concentrations (< 10 mg/l) the blank value of the preparation water must be taken into account. Especially for measurements in the lower concentration range (< 1 mg/l) a multiple point calibration with variable metering volumes and constant concentration can be used. The syringe pump is highly linear.

  • Page 37: 4.5.3.1 Tc/Npoc

    Technical description The net integer is the raw integer corrected by the preparation water. The regression type (linear or quadratic) can be defined by the user. It is possible to select individual measuring points or measured values for the calculation of the current calibration (manual outlier selection).

  • Page 38: 4.5.3.4 Npoc Plus

    Technical description The calibration takes place parallel by default, usually with mixed standards (e.g. car- bonate/hydrocarbonate and potassium hydrogen phthalate or saccharose). The calibration of the TIC and TC channel can also be carried out consecutively with sepa- rate standards. This is often useful if different ranges are to be calibrated for TC and TIC. 4.5.3.4 NPOC plus The method NPOC plus is calibrated the same way as the method TOC(Diff).

  • Page 39: Other Calculations

    Technical description Standard deviation of the method The standard deviation of the method describes in a unique and general way the quality of the calibration. For the unique evaluation of the quality the standard deviation of the method must be used. Method variation coefficient The variation coefficient of the method (relative standard deviation of the method) should be used for the comparison of different calibrations with different calibration ranges.

  • Page 40: System Suitability Test (Sst)

    Technical description Outlier selection The control and analysis software multiWin offers the option for an automatic outlier selec- tion. In the method a maximum limit for a variation coefficient or also for a standard deviation can be entered. The minimum number of measurements agreed in the method will be carried out. If the dis- tribution of the measured values is then above the agreed value (SD or VC) additional injec- tions are carried out from the same sample until the specified maximum number of meas- urements has been reached.
