A252035031C
2035 Process Analyzer - ThermometricThe 2035 Process Analyzer for Thermometric Titration performs automated titrations with a fast-responding, highly sensitive temperature sensor. Instead of the electrochemical potential, the endpoint is determined by enthalpy, i.e., by change in temperature of the solution during the titration. Thermometric titration is by far the most robust titration method available on the market and is excellent for 24/7 online process applications, such as the monitoring of etching baths. No sensor calibration is necessary, and less cleaning steps are needed. Rapid analysis is possible with this technique; acid mixtures, e.g., can be analyzed in less than three minutes.Thermometric titration can be used for a wide variety of titration analyses and is well-suited to handle aggressive sample matrices because of the robust thermometric sensor. The sensor needs no maintenance because fouling and other undesired interactions are minimal, and there are no membrane or diaphragm problems as with other titration methods. Thermometric titration is a problem solver for difficult samples which cannot be titrated potentiometrically, and is also a preferred technique in situations when HF is present in samples.

- 8.000.60538.000.6053Trace-level determination of perfluorinated compounds in water by suppressed ion chromatography with inline matrix elimination
This poster describes a simple and sensitive method for the determination of perfluorooctanoate (PFOA) and perfluorooctane sulfonate (PFOS) in water samples by suppressed conductivity detection. Separation was achieved by isocratic elution on a reversed-phase column thermostated at 35 °C using an aqueous mobile phase containing boric acid and acetonitrile. The PFOA and PFOS content in the water matrix was quantified by direct injection applying a 1000 μL loop. For the concentration range of 2 to 50 μg/mL and 10 to 250 μg/mL, the linear calibration curve for PFOA and PFOS yielded correlation coefficients (R) of 0.99990 and 0.9991, respectively. The relative standard deviations were smaller than 5.8%.The presence of high concentrations of mono and divalent anions such as chloride and sulfate has no significant influence on the determination of the perfluorinated alkyl substances (PFAS). In contrast, the presence of divalent cations, such as calcium and magnesium, which are normally present in water matrices, impairs PFOS recovery. This drawback was overcome by applying Metrohm`s Inline Cation Removal. While the interfering divalent cations are exchanged for non-interfering sodium cations, PFOA and PFOS are directly transferred to the sample loop. After inline cation removal, PFAS recovery in water samples containing 350 mg/mL of Ca2+ and Mg2+ improved from 90…115% to 93…107%.While PFAS determination of low salt-containing water samples is best performed by straightforward direct-injection IC, water rich in alkaline-earth metals are best analyzed using Metrohm`s Inline Cation Removal.
