Optimized Water Analysis: How to Ensure Quality Control & Meet Regulatory Requirements

In this video, Dr Edward F. Askew pinpoints the benefits of using Spectroquant Test Kits for water analysis, as well as tackling some frequently asked questions about industry regulations and quality control. Dr Askew is President of Askew Scientific Consulting LLC, a research lab and consultancy that has worked with Merck KGaA to produce the kits which are designed to meet method equivalency for EPA, clean water act methods and safe drinking water act methods.

Spectroquant® quality assurance for photometers

Merck KGaA, Darmstadt, Germany

The Spectroquant® analysis system includes photometers with cell tests and reagent tests which can be identified by barcodes pre-diluted standard solutions in various concentrations for increased reliability requirements residue-free cleaning agents Three-stage concept for internal controls Photometer Check - AQA 1 Easy to perform with certified color standards and/or Certipur® UV/VIS standards. System Check - AQA 2 Reliable documentation by measuring the recovery with CombiCheck standard solution, Certified Reference Material standard solutions (CRM), or Certipur® standard solutions. Matrix Check - AQA 3 Through one-time spiking with CombiCheck R-2 solution or multiple dilution/spiking with self-prepared solutions. Error-free results with analytical quality assurance With the Spectroquant® analysis system Merck Millipore offers a complete analytical quality assurance (AQA) concept for all Spectroquant® photometers. This allows users to be sure at all times that laboratory processes are running within defined minimum margins of error from beginning to end, providing reliable measurement results. Merck Millipore's ammonium standard solutions for photometric applications have an expanded measurement uncertainty of no more than 0.012 mg/l.
