The Aurora 1030D TOC Analyzer is twice as efficient with its ability to analyze TOC by both the heated persulfate wet oxidation technique and high temperature combustion method. This allows for measurement of aqueous samples and other samples of a higher molecular weight all from one single instrument! Heated Persulfate Wet Oxidation The heated persulfate oxidation technique has been approved and adopted in numerous regulatory compliance methods, standards, and norms for water quality testing, including: Standard Method 5310C, USEPA 415.3, USP <643> / EU 2.2.44, ASTM D 4779 and 4839, USEPA-DBPR, USEPA-SPCC, ISO 8245, and EN 1484.  In wet oxidation mode the 1030D reaction chamber is thoroughly rinsed between analyses to eliminate residue from the previous sample. This ensures a low system background necessary for high sensitivity TOC measurements.  High Temperature Combustion High temperature (680 °C) catalytic combustion is most effective for samples containing high molecular weight, difficult-to-oxidize organics (e.g.; humic acid) at levels > 500 ppb C. Our patented two chamber combustion tube of the 1030D contains a bed of quartz in the first chamber to protect platinum catalyst in the second chamber from deposition of non-combustible constituents. This design extends catalyst life, ensures consistent oxidation conditions, and reduces instrument maintenance costs. 

Make your analyses simple, quick, and accurate with our Model 1088 Rotary Autosampler. Specifically designed to work with all Aurora 1030 TOC Analyzer models (1030W, 1030C, and 1030S), this gem fits conveniently under the TOC analyzer. A removable 88-position autosampler tray loads the sample vials for fully-automated operation. The 1088 supports a number of special functions to address a range of sample conditions and analysis requirements. Onboard magnetic stirring ensures samples containing insoluble components or particles are homogeneous for sampling and accurate analysis. Septum piercing provides closed vial sampling to prevent contamination of the sample. System configuration for sample pretreatment allows pre-acidification and purging of samples within the 1088 prior to sampling.

Анализатор общего органического углерода методом персульфатного окисления. Принцип работы Анализатор Aurora 1030W реализует многоступенчатую методику анализа для количественного определения различных видов углерода, присутствующих в матрице образца. Определение производится прямым методом путем кислотного разложения неорганических угле- родсодержащих солей и последующей регистрации со- держания неорганического углерода, а затем окисления персульфатом натрия для определения органического углерода (ТОС). Содержание общего неорганического углерода определя- ется путем добавления к образцу 5% фосфорной кислоты до pH < 2. Карбонаты и бикарбонаты в образце диссоциируют и выделяют CO2 . Количество последнего измеряется твер- дотельным недисперсионным ИК-анализатором (SSNDIR) и пересчитывается в значения массы и концентрации. После удаления неорганического углерода в реакционную камеру добавляется персульфат натрия при температу- ре 98 °C. Нагревание и реакция протекают в течение трех минут. При взаимодействии с нагретым персульфатом на- трия происходит окисление органических соединений с вы- делением CO2 , который, в свою очередь, регистрируется недисперсионным ИК-детектором. В результате произво- дится определение массового содержания и расчет коли- чества и концентрации TOC в образце. Анализатор Aurora 1030W также поддерживает и другие методики анализа, включая определение общего орга- нического углерода дифференциальным методом по разнице между содержанием общего и неорганического углерода (TC–TIC). Общий углерод определяется после одновременного введения в камеру образца, кислоты и персульфата при 100 °C. Объекты анализа  Сточные воды, морская вода, поверхностные воды, про- мышленные воды, питьевая вода, вода для охлаждения, ультрачистая вода, вода для инъекций, полупроводники, вода для фармацевтики.

Move over Total Kjeldahl Nitrogen (TKN) testing. There’s a new total nitrogen analyzer in town, and it draws a quick analysis time of 10-15 minutes… The Aurora 1030C TNb Module measures the total bound nitrogen (TNb) content of water samples to provide an indication of the amount of pollutants present in those samples. Total bound nitrogen consists of dissolved ammonia, nitrates, nitrites, amines, and other nitrogen-containing compounds. The TNb analysis module is an optional accessory for the Aurora 1030C TOC analyzer that allows measurement of total bound (inorganic and organic) nitrogen (excluding N2) concentrations in aqueous samples. Total nitrogen can be measured simultaneously during NPOC and TC analysis or as a separate function when operated in the TNb analysis mode. Principal applications include: drinking water, wastewater, sewage effluent, agricultural runoff, and surface water. Methods used include: EN-12260 and DIN-ISO 11905-2. Aurora 1030C TNb Module Features: Direct measurement of Total Nitrogen (TNb) concentration in aqueous samples Faster analysis time than Total Kjeldahl Nitrogen (TKN) testing (10–15 minutes versus 2–3 hours) High temperature combustion used in the Aurora TNb is more effective for difficult sample matrices such as brines and particulates Eliminates labor and hazardous chemical exposure associated with TKN digestion TNb module mounts onto the Aurora 1030C TOC Analyzer, requiring no additional lab benchspace

Smartly designed, the compact instrument saves bench space while it is hard at work combusting solid materials, soils, sludge, slurries, and powders for TC and TOC analysis.  Principle of Operation Total organic carbon (TOC) is determined by manually transferring and weighing a solid sample into a quartz sample cup. The total inorganic carbon (TIC) content is removed from the sample by adding acid and heating to drive off CO2 released from inorganic carbon compounds. In the case of total carbon (TC) analysis, the pre-acidification step to remove TIC content is not required. The sample cup with the TIC-free sample is placed on the lift mechanism and raised into the combustion tube of the 1030S. The sample is heated to 500° - 900 °C inside the furnace. Organic matter in the sample is oxidized and converted to CO2 which is collected in a one liter capacity gas sampling bag. When the combustion cycle is complete an aliquot of the CO2 sample gas is transferred to the NDIR detector in the Aurora 1030 analyzer for measurement of the mass of carbon in the sample. 1030S Features: Combusts solid materials soils, sludge, slurries, and powders for TC and TOC analysis Interfaces with Aurora 1030 TOC analyzer allowing analysis of both solid and liquid samples using a single instrument Gas sampling device (patent pending) collects carbon dioxide (CO2) from sample combustion for quantitation and analysis of intra-sample replicates Compact vertical design saves laboratory bench space
