Test Kits and Photometric Methods On-Demand Webinars

Did you miss the live webinar? Catch up on all the technologies and troubleshooting tips for test kits and photometric methods by watching our collection of on-demand webinars.

Ultra-Sensitive Silicate Analysis in Process and Boiler Water

Sept. | 2017
  • Presenters: Bruce Herzig, Application Scientist, Merck
  • Abstract

    The webinar will discuss photometric methods for analysis of silicate in boiler and process water using an ultrasensitive photometric technique. This technique is presented as an alternative to the graphite furnace atomic absorption technique. The webinar is aimed at anyone performing water analysis on boiler and cooling water, and/or anyone interested in silicate analyses. By attending this webinar you will learn:

    • About ultrasensitive photometric methods for measuring silicates in boiler and process water
    • Instruments and test kits from Merck KGaA for the application of this technique
    • Comparison data to GFAAS methods


UV-vis Spectrophotometric Analysis of Water, Food, and Beverages

Measuring Phosphate in Ground and Surface Water

Sept. | 2016
  • Presenters: Carolin Klein, Global Product Manager, Photometry, Merck; and Onur Akbulut, Regional Field Marketing Manager, Advanced Analytics, Merck Turkey, MENAPT+, Turkey
  • Abstract

    Separation Science, in collaboration with Merck KGaA, Darmstadt, Germany, has developed an online eSeminar focusing on the use and application of UV-vis spectrophotometry for the analysis of water. This event will provide scientists with updates on the latest issues faced by individuals working in these challenging analytical fields. Taking place in a 1-hr session, this unique event will feaure technology experts and provide an interactive learning environment and online resource.

    Featured Speakers and Presentations:

    • Sensitive and Reliable Measurement of ortho-Phosphate in Ground and Surface Water
      by Carolin Klein
      This presentation concentrates on a photometric method that can be used to detect ortho-phosphate levels as low as 2.5 µg/L. Examples demonstrated are surface water samples from lakes in Germany with their phosphate levels measured using photometry. This is an important application, because too high levels of phosphate may pose a risk to both human health and the environment.

    • Analysing Phosphonates in Cooling and Boiler Water
      by Onur Akbulut
      Organic phosphonate salts are mainly used in industrial cooling and boiler water applications. As antiscalants and corrosion inhibitors, the main purpose of phosphonates (organic phosphorus) is to reduce scale and remove rust, and thus lower maintenance costs. For an efficient and smooth-running system, both dosing and monitoring the concentration of phosphonates(in circulation in the system), are crucial for boiler water. Therefore, accurate and sensitive determination of phosphonates is necessarily the cornerstone of laboratory analysis.


    Multiple Fast and Easy Possibilities for Disinfection Control

    April | 2015
    • Presenters: Carolin Klein, Global Product Manager, Photometry, Merck
    • Abstract

      Disinfection control and monitoring of disinfection residues in water is an important topic in many industries – especially Food and Beverage. Learn about the advantages and disadvantages of different disinfectants such as chlorine, ozone, chlorine dioxide and cyanuric acid, and which disinfectant is the best choice for specific applications.

      This webinar presents different possibilities for monitoring disinfection residues. Attendees will learn about fast and easy control with a test strips, along with an easy photometric measurement of disinfection parameters with the new mobile colorimeter - Spectroquant® Move Cl2/O3/ClO2/CyA/pH.

      What will you learn?

      • Different possibilities for disinfection and their advantages and disadvantages
      • How to make disinfection control efficient and easy
