    Know your ions – overcoming the limits of HPLC with ion chromatography

    What’s the difference between High Performance Liquid Chromatography (HPLC) and Ion Chromatography (IC)? What are the capabilities and limitations of each technique? Knowing these differences can actually make a huge difference. As a proven, robust and highly versatile technique, IC can help HPLC users extend their analytical capabilities tremendously. Our free white paper compares the two methods systematically focusing on the strengths of ion chromatography.

    Thermometric titration – fast and highly accurate determination of metal organic compounds

    Due to their highly reactive nature, metal organic compounds require sophisticated sample preparation. Butyl lithium, a rather instable compound, which readily reacts with water and oxygen, is an example. For quality control and further usage it is therefore important to determine their exact content. With thermometric titration, Metrohm offers a method that is fast, robust, and very reliable for measuring metal organic compounds.

    Quality control of NPK fertilizers – Rapid and reliable analysis by thermometric titration

    Metrohm is pleased to present several titrimetric applications for the fast and straightforward of macronutrients such as sulfate, ammonium, potassium, and phosphate in NPK fertilizers. The reaction endpoint is determined using a thermometric sensor. Unlike competing methods such as gravimetric analysis or flame photometry, thermometric titration usually requires no sample preparation at all, and it is also faster, more robust, and easier to use.

    Water in lithium ion battery materials – Reliable and precise determination by Karl Fischer titration

    Lithium ion batteries are energizing the current mega trend towards electrical mobility. One of the key requirements of lithium ion batteries is that they must be free of water, because water reacts with the conducting salt of the electrolyte. A proven and reliable method to measure the water content in the electrolyte matrix of lithium ion batteries directly is coulometric Karl Fischer titration.

    Total sodium in foodstuffs – new video explains the better determination method

    A commonly used method for quantifying sodium in foodstuffs is to determine chloride and subsequently deduce the sodium concentration from the 1:1 stoichiometry of sodium chloride. This method involves errors because sodium is not only present with chloride as the counterion. A direct thermometric titration method for sodium solves this problem. In a new Metrohm Application Video, Lucia Meier, product specialist titration at Metrohm International Headquarters, presents this method.

    Knowing the real corrosion potential of fuel ethanol – measuring pHe according to ASTM D6423

    Excessive acidity in alcohol based fuels accelerates engine corrosion. Total Acid Number (TAN) accounts for all titratable acids regardless of their strength and is therefore not suitable to accurately predict the corrosion potential. pHe, on the other hand measures the strength of the acids present in the sample. Therefore, pHe is the better parameter for manufacturers to monitor the corrosion potential, maintain the quality of their product, and maximize profits.
