- AN-P-087AN-P-087Quality labels for novel foods
This Application Note presents an update to the standard AOAC method for total GOS determination in foodstuffs.
- AN-BAT-016AN-BAT-016EIS at different states of charge with INTELLO
This application shows how EIS, combined with INTELLO and NOVA, tracks changes in internal battery resistance across SOC levels to study performance and aging mechanisms.
- AN-C-197AN-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>.
- AN-CS-021Sodium in sodium bicarbonate and sodium phosphates compounded injections
Compounded injections of sodium bicarbonate are sterile solutions for correcting metabolic acidosis and other conditions requiring systemic alkalinization. Compounded injections of sodium phosphates serve as a phosphate source to either prevent or correct hypophosphatemia in patients with restricted oral intake. Ion chromatography (IC) with suppressed conductivity detection is the standardized way to accurately quantify sodium in these solutions.
- AN-FLU-002Understanding the mechanism of a bioassay indicator by fluorescence
Alamar Blue is monitored with fluorescence spectroelectrochemistry during its irreversible reduction to resorufin and further reversible reduction to dihydroresorufin.
- AN-NIR-022Quality Control of Gasoline
In recent years, there has been a significant push to reduce the environmental impacts of fuels through improvements to fuel quality. The determination of key quality parameters of gasoline, namely research octane number (RON, ASTM D2699-19), motor octane number (MON, ASTM D2700-19), anti knock index (AKI), aromatic content (ASTM D5769-15), and density, conventionally requires several different analytical methods, which are laborious and need trained personnel. This application note demonstrates that the XDS RapidLiquid Analyzer, operating in the visible and near-infrared spectral region (Vis-NIR), provides a cost-efficient and fast solution for the multiparameter analysis of gasoline.
- AN-S-375Fluoride in sodium fluoride for pharmaceutical use
Dental care products often contain sodium fluoride as an active ingredient. Manufacturers use the United States Pharmacopeia and National Formulary (USP-NF) Monograph «Sodium Fluoride» to quantify sodium fluoride and its anionic contaminants chloride and acetate in these products. The validated USP method proposes ion chromatography (IC) with suppressed conductivity detection to carry out the fluoride assay as well as the impurity determination in a single chromatogram.
- AN-S-376Fluoride in sodium fluoride gel for pharmaceutical use
Sodium fluoride gel for pharmaceutical use needs to comply with USP requirements. The actual monograph (USP 42) uses two different methods for the identification and the assay. Ion chromatography allows the analysis of these two parameters in one single determination. In the course of the USP monograph modernization, this ion chromatographic approach makes this type of analysis even easier.
- AN-S-379Fluoride in sodium fluoride tablets for pharmaceutical use
Sodium fluoride tablets for pharmaceutical use need to comply with U.S. Pharmacopeia (USP) requirements. Ion chromatography (IC) with suppressed conductivity detection has been approved by the USP as a validated method to quantify fluoride content in sodium fluoride tablets. In the course of the USP monograph modernization, using automated IC makes this type of analysis even easier.
- 26 lut 2024Certyfikowanie i gwarancja wysokiej jakości oraz zgodności w środowiskach podlegających przepisom prawnym
Wyposażenie Metrohm, które zostało objęte certyfikatem AOAC dotyczącym kwalifikacji instalacji i operacyjności (Q2), przynosi poczucie pewności, ułatwiając jednocześnie spełnianie wymogów regulacyjnych.
- 14 wrz 2020History of Metrohm IC – Part 3
Blog post on Metrohm ion chromatography and the introduction of sequential suppression for increased sensitivity in ion chromatographic analysis.
- 18 lis 2024Chromatografia jonowa dla przemysłu farmaceutycznego
Przedstawiono zasady chromatografii jonowej, a następnie niektóre zastosowania i korzyści wynikające ze stosowania chromatografii jonowej w analizie farmaceutycznej zgodnie z rozdziałem ogólnym USP <1065>.
- 25 maj 2020Photometric complexometric titration
What is photometric complexometric titration and how does it work, read our chemistry blog.
- 16 paź 2023Stosowanie metod zatwierdzonych przez USP w celu sprawdzenia równoważności kolumn separacyjnych
Modernizacja Monografii USP pozwala obecnie na szerszy wybór kolumn separacyjnych do analiz farmaceutycznych z wykorzystaniem chromatografii jonowej (IC). Badania równoważności kolumn umożliwiają stosowanie alternatywnych kolumn analitycznych bez konieczności stosowania skomplikowanych procedur walidacji metod. Przynosi to korzyści badaczom branży farmaceutycznej, oszczędzając czas i wysiłek, zachowując jednocześnie dokładność i wiarygodność wyników analitycznych zgodnie z zatwierdzonymi metodami.
- 8.945.50018.945.5001Brochure: 945 Professional Detector Vario IC Amperometric Detector – Amperometric detection for the determination of electroactive substances
Amperometric detectors are an alternative to conductivity and UV/VIS detectors. They are used when electroactive – i.e. oxidizable or reducible – substances are to be determined. The amperometric detector exists as an embedded detector – the IC Amperometric Detector – and as a stand-alone detector – the 945 Professional Detector Vario. The present brochure describes these two instruments
