    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.

    Substituting chromium – thermometric titration method allows aircraft manufacturer to streamline monitoring of anodizing baths

    One of the biggest players from the aerospace industry has replaced chromium in their anodizing process of aircraft parts by a mix of sulfuric and tartaric acid (TSA, Tartaric Sulfuric Anodizing). Metrohm developed a new method allowing this customer to determine both acids quickly and reliably using the same sensor, a highly sensitive, fast responding thermometer. An Application Note describing this application is available free of charge from Metrohm.

    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.

    The 2060 MARGA – a re-invented way of air quality monitoring

    Ambient air quality is critical for our health and the environment. According to the World Health Organization 91% of the world population lives in places where the WHO air quality guideline levels are not met. To monitor the air quality, Metrohm Process Analytics has re-invented the well-known Monitor for AeRosols and Gases in ambient Air (MARGA) as the 2060 MARGA.

    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.

    Fully automated water conductivity testing safeguards compliance with USP<645>

    USP<645> describes conductivity as key parameter for measuring the purity of ultrapure water and water for injection. Compliance with USP<645> is key for manufacturers from the pharmaceutical industry. However, following the three stage test procedure defined by the standard can be a challenge, particularly if the testing is performed manually. A dedicated Metrohm system provides a fully automated solution to this challenge reducing the risk of error while increasing productivity.
