- AN-C-191AN-C-191Sodium in lanthanum acetate
Lanthanum (La) is a transition metal which oxidizes easily in air to lanthanum(III) oxide. This oxide, as well as salts resulting from its dissolution in acid and recrystallization, is a component of different catalysts. Here, a lanthanum(III) acetate solution prepared by dissolution of lanthanum(III) oxide in acetic acid, has to be tested for a sodium contamination. The high concentration of La3+ is complexed by the dipicolinic acid in the eluent and forms anionic complexes. These complexes are eluted in the front and therefore do not interfere with the sodium impurity as well as other cations such as ammonium and calcium.
- AN-C-192AN-C-192Cations in sodium rich wastewater
Wastewaters often contain high loads of sodium, making the determination of minor cations quite a challenge. In the present wastewater study, the determination of lithium, ammonium, zinc, strontium, and barium is requested. If the sodium concentration exceeds 2 g/L, this negatively influences the peak shape of closely eluting peaks. Applying a appropriate dilution factor to the sample enables the quantification of minor cations. Therefore zinc and barium can be properly quantified with a dilution ratio of 1:2, while lithium and ammonium require minimum dilution factors of at least 1:10 and 1:100, respectively.
- AN-C-193Alkyl amines in scrubber solutions
Harmful industrial flue gases like H2S and CO2 cause corrosion of pipes and damage the environment. Adding the correct amount of amines in scrubber solutions, e.g. ethanolamines and methylamines, will neutralize these gases («gas sweetening»). Non-suppressed cation analysis with direct conductivity detection is a straightforward and robust technique for the quantification of monoethanolamine (MEA), diethanolamine (DEA), triethanolamine (TEA), monomethylamine (MMA), dimethylamine (DMA), and trimethylamine (TMA) via ion chromatography. Thanks to the high capacity of the Metrosep C 6 column, large volumes can be injected without compromising the peak shapes. The analytical technique can be used at laboratory scale but also for process analysis.
- AN-C-194IC Assays for Calcium and Magnesium according to USP
Calcium carbonate has a wide applicability in the pharmaceutical industry as an excipient and also as an active ingredient, and in the food industry as a major dietary supplement. The U.S. Pharmacopoeia (USP) monographs for calcium and magnesium carbonates tablets as well as calcium carbonate and magnesia chewable tablets currently describe manual titration as the assay procedure for calcium and magnesium. The USP has embarked on a global initiative to modernize many of the existing monographs across all compendia. In response to this initiative, two alternative analytical methods were developed to determine the analytes calcium and magnesium. This Application Note presents ion chromatography (IC) procedures using conductivity detection that provide better accuracy and specificity and are suitable for the intended purpose. These validated IC methods (according to USP General Chapter <1225>) offer a significant improvement to the existing assays because they can simultaneously determine both analytes calcium and magnesium, saving both time and effort.
- AN-C-195Cation quantification with increased performance using microbore IC
Microbore ion chromatography offers better sensitivity, shorter retention times, and consumes less eluent, increasing sample throughput and reducing running costs.
- AN-C-196Purity quantification of tris(hydroxymethyl)aminomethane (TRIS) with IC
Tris(hydroxymethyl)aminomethane (TRIS) is often used in life science applications and its purity must be monitored. This analysis is possible with ion chromatography.
- AN-C-197Potassium assay in potassium citrate and citric acid oral solution
Potassium citrate and citric acid oral solutions act as systemic alkalizers. Potassium assays, validated per USP <621> and <1225>, use IC with L76 cation-exchange columns.
- AN-C-198Calcium acetate assay in calcium acetate capsules
The assay of calcium acetate, often used as a phosphate binder for dialysis patients, can be performed with ion chromatography (IC) as per USP <621> and <1225>.

Laboratory Practice - Determination of L-lactic acid in winesThese practical kits allow students with or without electrochemical experience to complement their academicprograms by an inquiry-based learning on research experiences. They are also useful for those researchers that are starting in the biosensing field.Lactate detection is of great importance in a wide range of areas, including the wine industry, where it is frequently used as key indicator of wine quality. Amperometric biosensors for lactate detection, used in this practice, are an optimal alternative to perform this analysis since they allow the selective detection of this analyte at low concentrations in a simple way. The main goals in this laboratory teaching kit are: defining the detection potential, studying the inter-electrode reproducibility, the establishment of a calibration curve, and the measurement of L-lactic acid in wine samplesThe kit contains:• The professor outline• The student outline• A box of suitable screen-printed electrodes shipped in an isulated kit (50 units)

Laboratory Practice - Determination of chloride in synthetic sweatThese practical kits allow students with or without electrochemical experience to complement their academicprograms by an inquiry-based learning on research experiences. They are also useful for those researchers that are starting in the biosensing field.The determination of chloride in synthetic sweat plays a key role in the early diagnosis of cystic fibrosis (CF) in people of all ages. People with CF have a high level of chloride in sweat. In voltametric sensors the analytical signal usually employed is the peakcurrent generated when a suitable potential window is scanned. This peak current is related to the concentration of the analyte. The main objectives of this didactic laboratory kit are the establishment of a calibration curve to study the accuracy of the procedure for the determination of chloride in synthetic sweat sample.The kit contains:The professor outline; The student outline; A box of suitable screen-printed electrodes (50 units); Solid NaCl (300 mg); Sinthetic sweat (3 solutions with different concentrations);

Laboratory Practice - Determination of hydrogen peroxide in milkThese practical kits allow students with or without electrochemical experience to complement their academicprograms by an inquiry-based learning on research experiences.They are also useful for those researchers that are starting in the biosensing field. Hydrogen peroxide can be found in milk at different stages of its processing. Despite this, the addition of peroxide to milk in any concentration is not allowed in many countries including EU. This is the reason why developing economical and accurate devices for the determination of its existence in the whole line of milk processing must be done.The main objectives of this laboratory kit are the establishment of a calibration curve, analysis of the analytical performance of the sensor and evaluation on the precision of the assay for the determination of hydrogen peroxide in milk.The kit contains:The professor outline; The student outline; A box of suitable screen-printed electrodes (50 units);

They are also useful for those researchers that are starting in the biosensing field.According to European regulations, the labelling of drinks containing more than 1.2% by volume of alcohol must indicate the actual volumetric alcoholic strength. Due to the health and legal importance that implies showing the alcohol content of a beer in its label, it is important to determine its percentage with good precision and selectivity.The main goals in this laboratory teaching kit are studying the establishment of a calibration curve and the determination of the alcohol content in samples of commercial beers by employing a fast and easy electrochemical assay. The kit contains:The professor outline; The student outline; A box of suitable screen-printed electrodes (50 units);
