formacs2The FormacsSERIES Total Organic Carbon (TOC) and Total Nitrogen analysers offer the perfect solution for rapid and reliable tests for Carbon and/or Nitrogen in samples coming from a variety of natural, domestic and industrial sources. Depending on the samples, application and laboratory requirements, a choice of analysers is available.

Formacs HT/Formacs HT-I

Formacs HT 6a thumbThe FormacsHT high temperature catalytic combustion system features a versatile modular design and excellent performance for the analysis of Total Carbon (TC), Total Inorganic Carbon (TIC), Total Organic Carbon (TOC), Dissolved Organic Carbon (DOC) and Non-Purgeable Organic Carbon (NPOC).  This design was developed to conform to the latest customer requirements and allows the determination of TOC in clean waters such as pharmaceutical - and drinking waters but also performing equally well for the analysis of waste, surface, seawater and soil extracts.

It can be operated as a stand-alone analyser where sample and standard solutions are introduced directly through a rotary septum-less injection port for analysis of TC and TIC.

For larger sample numbers an optional random access auto-sampler is available for complete automation of the TOC determination. The auto-sampler is available with different carrousels for vials with different volumes. Sample pre-treatment for NPOC determination is fully controlled by the operation software and can be set in preferred mode by the operator. The instrument has the possibility with a dual needle set-up to acidify and purge the following sample while analysing the current one, which saves valuable analysis time.

The FormacsHT-I TOC/TN analyzers provide fast, reliable analysis of TOC and TN in liquid samples by direct sample injection into a high temperature catalytic combustion furnace. The units are especially designed for particulate laden samples (suspensions), but can handle the concentration of nitrogen and/or carbon fractions from various other sample matrices.

Formacs TN

ND25 thumbThe FormacsTN Analyzer uses the ND25 Total Nitrogen detector for the analysis of Total Nitrogen (TN). TN can be measured in a range from low ppb levels to high ppm levels with high accuracy in a short analysis time using chemiluminescence detection (CLD).

The sample is injected into the high temperature furnace where it is catalytically combusted at 850°C. Oxidative pyrolysis causes the chemically bound nitrogen to be converted to nitric oxide, which is measured by CLD The FormacsTN analyzer also provides a unique cost-effective and safer alternative for Total Kjeldahl Nitrogen (TKN) analysis, by an integrated NN-reactor for the analysis of NO3 + NO2 (NN). The TKN value is determined in two steps, i.e. the analysis of TN and the analysis of NN via chemical reduction, where NO3 and NO2 are reduced to nitric oxide (NO) and detected via CLD detection. The TKN value is obtained automatically by subtraction: TKN = TN - NN. This unique alternative method of TKN analysis results in a very fast analysis time (5 min.), and eliminates the use of hazardous digestion acids.

Primacs2PrimacsSERIES is the range of Carbon / Nitrogen analysers perfectly made for solid samples. Depending on the application and laboratory requirements, there are a few models available.

PrimacsSNC-100

Primacs SNC 100 sideThe PrimacsSNC-100 is the latest, modern and flexible sample analyser with integrated 100-position autosampler for determination of Nitrogen (N), Protein, Total Carbon (TC), Total Elemental Carbon (TEC), Total Inorganic Carbon (TIC) and Total Organic Carbon (TOC) all in one unit.

The analyser provides fast, reliable, accurate and low level analysis of these parameters in applications such as soil & plant, sludges & sediments, animal feed & grain, food, malt & wort, fertilizer etc.

The PrimacsSNC-100 consists of an extra-large integrated autosampler with 100 positions covered with a transparent lid. The sample rack is removable and re-usable quartz or ceramic crucibles are used for sample weights up to 3 g of solid material. Samples are introduced in the analyser through a unique vertical sample introduction system. Sample ashes remain in the crucible after the analysis and are taken out of the instrument with removal of the crucible. This avoids sample ash build-up in the combustion zone and therefore reduces maintenance.

High temperature combustion with Non Dispersive Infrared detection (NDIR) is used for the analysis of TOC, TEC and TIC. The temperature settings are variable to get optimum combustion for different sample matrices and to allow the analysis of TEC. TIC can also be analysed using automatic acidification and purging.

The determination of TN/Protein is based upon DUMAS methodology and detection with Thermal Conductivity (TCD). The DUMAS method is fast, safe and a good alternative from Kjeldahl for laboratories wanting to move away from chemicals/acid-usage and prefer a rapid and reliable method.

PrimacsMCS

Primacs MCS HT 1bPrimacsMCS is an add-on module for TOC analysis for solid materials such as soil, sediments and sludges. The PrimacsMCS operates in combination with the FormacsSERIES TOC analyser for liquid samples, offering an economical concept to environmental laboratories for TOC analysis on aqueous samples.

The PrimacsMCS is equipped with a dual-oven design, allowing separate analysis of Total Carbon (TC) and Inorganic Carbon (IC). TC is determined by catalytic oxidation of the sample at 1100°C, converting the carbon present in the sample to CO2, which is detected by the NDIR detector of the FormacsSERIES Total Organic Carbon analyser. IC is determined by acidification of the sample in the IC reactor, which converts the Inorganic Carbon to CO2. The PrimacsMCS software collects the data and calculates the TOC concentration of the sample by substraction (TC - IC = TOC).

The PrimacsMCS analyses TC, IC and TOC in a range of 500 µg to 40 mg absolute carbon in up to 3 g of sample weight. Due to the automatic low-to-high range switching IR detector of the FormacsSERIES TOC analyser, the combination of the FormacsSERIES analyser with the PrimacsMCS add-on module offers environmental laboratories a powerful tool to analyse TOC from low ppb concentrations in aqueous samples up to ppm levels in solid materials. The PrimacsMCS conforms to international regulations such as EPA, ISO, NEN-EN 13137 and US EPA 9060.

PrimacsSLC

Primacs SLCThe increasing demand for reliable TOC analysis in solid materials such as sludges, sediments and soils have led Skalar to complement its range of TOC analysers with the PrimacsSLC analyser. Based on a dual oven design the analyser is capable of performing rapid, reliable, separate determinations of TC, IC and TOC on one instrument, and has been developed especially for solid materials on sample weights of up to two grams. Automatic balance interfacing avoids the necessity of error-free typing of weight data. The reusable quartz and ceramic crucibles combined with the unique vertical sample introduction system and fully computerized operation/calculation, make the PrimacsSLC the most economical choice in today's environmental laboratory.

The PrimacsSLC conforms to international regulations such as ISO and NEN-EN 13137 and US EPA 9060.
