    QC and optimization of coating processes in chrome plating with IC

    For an efficient plating process, chrome plating baths contain catalysts, such as sulfuric acid, MSA, or MDSA. Excessive catalyst concentrations can cause defects on the plating surface, while insufficient concentrations can impair the process and/or cause dull spots or burned deposits. Monitoring their concentration level is therefore a prerequisite. Ion chromatography (IC) is the ideal solution for monitoring catalyst concentrations, besides chromate and inorganic anions, such as fluoride or chloride.

    QC and optimization of coating processes using IC

    Surface finishing such as electroplating is one of the most important industrial processes to design products with dedicated physical, chemical, and electronic properties. Purity and composition of solutes, solvents, catalysts, and the electrolytic baths are a key requirement to achieve the desired properties, prevent damages and inferiority of the products by imbalances or contaminations. Ion chromatography (IC) is the ideal method for analyzing ionic impurities, even in the ng/L range.

    Analysis of stabilizers in electroless nickel baths

    Stabilizers play an important role in electroless nickel plating solutions as they control the plating rate and prevent uncontrolled plate out (decomposition) of the bath. However, it is important to hold the stabilizer concentration at an optimal level. Too low stabilizer levels negatively affect the deposition rate and bath stability. Too high levels can poison the deposition at the edges or stop the plating reaction. Learn more in the free application notes.

    Screening for per- and polyfluorinated alkyl substances (PFASs) in water

    Per- and polyfluorinated alkyl substances (PFASs) are the class of almost 10,000 manmade organofluorine compounds more commonly known as «forever chemicals». PFASs are resistant to water, oil, and heat. Due to their unique properties, they find widespread applications in many products and industries. They can enter the water supply and the food chain, causing various health problems in humans. The stability of these substances and their decay products, combined with their affinity to bind to proteins, makes them especially harmful. Targeted analysis methods only capture a small fraction of the variety of PFASs. Non-targeted screening methods offer a more comprehensive view of water quality by estimating the overall impact of organofluorine substances. Read more in this free white paper.

    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.
