Product Guide
Ammonium ion standard
A single-ion reference material for ion-chromatographic calibration and analytical quality checks. The named ion, concentration basis and matrix must match the method; a reagent salt is not a substitute for a documented reference solution.
Practical purchasing guidance for universities, research laboratories, industry and institutional buyers.
Applications and workflows
Typical workflows help you define the application and compare suitable product configurations.
- Instrument calibration and independent quality checks
- Chromatographic method development and quality control
- Raw-material identification and quality control
Technical selection criteria
Include these parameters in your inquiry to align laboratory users, technical teams and purchasing.
- Analyte, solvent matrix and concentration units
- Certified value, uncertainty and metrological traceability
- Concentration, units and preparation basis
- Shelf life, opening stability and storage instructions
Variants and compatibility
Reference solutions differ by analyte, certified value, matrix, uncertainty and expiry. Match all of these to the method; an ordinary reagent or another concentration is not a documented equivalent.
Documentation and delivery
Request the current safety data sheet and a specification or batch analysis appropriate to the intended grade. Confirm identity and impurities before substituting a salt, hydrate or grade. Transport status must be assessed for the supplied form and quantity.
Confirm the required documents, packaging and delivery conditions for the selected item and destination.
