- AN-C-144AN-C-144Variable Inline Preconcentration including matrix elimination for trace cation determination (MiPCT-ME)
Metrohm Inline Preconcentration Technique with matrix elimination (MiPCT-ME) is a powerful method that combines preconcentration, matrix elimination, and multilevel calibration. In this Application Note, the methodology is applied to the determination of traces of sodium in addition to 2 mg/L ammonia. The Metrosep C 6 - 250/4.0 column is used for selectivity reasons.
- AN-C-145AN-C-145Ammonium traces besides excess sodium using 940 Professional IC Vario and direct conductivity detection
The determination of low ammonium concentrations besides excess sodium is demanding due to the small retention time difference of these two cations. This Application Note shows direct conductivity detection as an ideal means to detect ammonium in a wastewater sample containing 400 mg/L sodium. AN-S-313 shows the analysis of nitrite traces.
- AN-C-146AN-C-146Bethanechol and HPTA (2-hydroxy-propyl-trimethyl ammonium) besides sodium and calcium (Metrosep C 6 - 250/4.0)
Bethanechol is a pharmaceutical compound which is used to treat urinary retention. This API (active pharmaceutical ingredient) can be determined by cation chromatography with direct conductivity detection. A good separation is achieved between bethanechol and its degradation product 2-hydroxy-propyl-trimethyl ammonium (HPTA) and the standard cations. Peak shape and resolution meet the USP requirements for bethanechol.
- AN-C-147AN-C-147Fast analysis of cations in tap water using Metrosep C 4 - 100/2.0
Reducing the analysis time is a demanding task because it is accompanied by a parallel reduction of peak resolution. With a Microbore column 100 mm in length, standard cations in tap water can be determined in only 5 minutes. Strontium can also be determined by simply extending the run time to 6.5 min.
- AN-C-148AN-C-148Metrohm Inline Dilution – Dilution factors of up to 10,000 in two intelligent steps
Sample dilution is a work-intensive routine task in the analysis laboratory. An automatic two-step dilution exponentiates the dilution factor – 1:100 – thus incorporating a dilution factor of 10,000. The intelligent dilution is made possible by MagIC Net, which calculates the essential dilution steps, and by the dosing properties of the 800 Dosino and the Liquid Handling Station. The Application Note shows statistical results of a 1:10,000 dilution.
- AN-C-149AN-C-149Determination of cations on surfaces of printed circuit boards
Cleanliness is indispensable in electronics production. Ionic contaminations in particular lead to a drastic worsening of the quality of the printed circuit boards. The present Application Note describes the determination of cations on printed circuit board surfaces. The intelligent Partial Loop Injection Technique (MiPT) used for this purpose permits the determination of cations and anions in the same sample. The determination of the anions is described in AN-S-317.
- AN-C-150AN-C-150Fast IC: Separation of standard cations in eleven minutes
Fast IC means short run times on separation columns with a relatively high flow rate and the standard eluent. Here the standard cations are separated within eleven minutes on the Metrosep C 4 - 250/2.0. The sodium and ammonium peaks are separated from one another under these conditions.
- AN-C-151AN-C-151Fast IC: Separation of standard cations in five minutes
Fast IC means short run times on separation columns with a relatively high flow rate. Separation with the Metrosep C 4 - 150/2.0 is even quicker than that in the AN-C-150 at 1.1 mL/min. Here, the standard cations are separated within five minutes. Under the selected conditions, sodium and ammonium are no longer completely separated.
- AN-C-152AN-C-152Fast IC: Separation of ethanolamines in 2.5 minutes
