- AN-CIC-035Halogens and sulfur in solid samples according to EN 17813
Organic halides must be monitored in the environment. Combustion ion chromatography (CIC) is used for accurate halogen analysis in solids following EN 17813:2023.
- AN-RS-018Trace Detection of Malachite Green in Stream Water
Malachite green (MG) is a textile dye with effective fungicidal properties, however it is acutely toxic and its metabolites persist in the flesh of fish and mammals, making it a threat to the human food chain. The EU has concluded that contaminated foods containing levels higher than 2 μg/g MG constitute a credible health risk, and several countries have banned malachite green as an aquaculture additive. Despite tight regulation, seafood products contaminated with MG continue to find their way to consumers. Using Misa (Metrohm Instant SERS Analyzer) to ensure food safety, the rapid and highly sensitive detection of malachite green is achieved in a facile assay format.
- AN-C-056Sodium, ammonium, methylamine, guanidine, and aminoguanidine in wastewater
Determination of sodium, ammonium, methylamine, guanidine (Gu), and aminoguanidine (Agu) in wastewater using cation chromatography with direct conductivity detection.
- AN-C-114Semi-continuous determination of cations in aerosol using PILS-IC
Determination of sodium, ammonium, potassium, magnesium, and calcium in an ambient aerosol (PM2.5) using aerosol sampling with the PILS (Particle Into Liquid Sampler) and cation chromatography with direct conductivity detection.
- AN-C-103Standard cations in lake water on the Metrosep C 3 - 250/4.0 column
Determination of lithium, sodium, potassium, magnesium, and calcium in lake water using cation chromatography with direct conductivity detection.
- 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-I-011Fluoride content in drinking water
Fluoride content in drinking water can be determined quickly and conveniently with the help of potentiometric titration and the ion-selective fluoride electrode (F-ISE). The F-ISE is calibrated with suitable standard solutions before the measurement.
- AN-I-019Ammonium in Soil – Reliable determination by Standard Addition with NH4 - ISE
Nitrogen is essential for plant growth. In soil, it can be present in the form of nitrate, ammonium, or urea. Knowing the nitrogen content of soil and in which form it is present helps selecting the right kind of fertilizer to stimulate plant growth. This Application Note shows a fast and reliable way to determine the ammonium concentration in soil by using standard addition.
- AN-M-013Chromium speciation by IC-ICP-MS
Differentiation between Cr(III) and Cr(VI) is possible following ISO 24384 guidelines by combining ion chromatography with inductively coupled plasma mass spectrometry.
- AN-M-017IC-MS/MS analysis of trifluoroacetic acid according to DIN 38407-53
The new DIN draft standard 38407-53 outlines TFA analysis in water using direct injection LC-MS/MS, enabling quantification from 0.1–3.0 μg/L as shown in this Application Note.
