Drinking Water Application Notes

41. Improved Determination Of Volatile Organic Compounds In Water By SPME And GC/MS 6/21/2018

    The analysis of water for volatile organic compounds is important due to their toxicity. The current methods for this determination lack of sensitivity, selectivity or capability for automation. This paper presents the new ISO 17943 Standard using Solid Phase Microextraction (SPME) and GC/MS. The sample preparation by SPME enables limits of detection and easy automation of the whole method. GC/MS provides the required sensitivity and selectivity. This ISO Standard was validated by an interlaboratory trial, which results confirm the outstanding performance for this method.

42. 'TOTEX' Is Key When Purchasing Instrumentation 4/29/2021

    There’s a lot to be considered in the price tag of an ultrasonic instrument. Derek Moore from Siemens explains how the historical way of thinking only of capital costs needs to change to the more holistic approach of total expenditures.

43. Phosphate In Groundwater And Surface Water: A Rapid And Reliable Determination Method Using The Photometric Spectroquant® Test 1/31/2019

    Phosphorus is an essential element for organisms and plants. In natural, uncontaminated waters, it occurs as organically bound phosphate, condensed phosphates or as orthophosphate — often referred to by its chemical formula PO₄-P. The small quantity of phosphorus present in natural waters does not promote the growth of plants. However, a rise in the concentration of phosphorus results in the proliferation of algae, which leads to the eutrophication of the water body.

44. Determination Of Pesticide Residues In Honey, By An Automated QuEChERS Solution 9/17/2014

    The QuEChERS (Quick-Easy-Cheap-Effective-Rugged-Safe) sample extraction method was developed for the determination of pesticide residues in agricultural commodities.

45. Removal Of Chloramines With Activated Carbon 12/30/2013

    In order to reduce the formation of harmful disinfection byproducts in drinking water, alternative disinfectant use has become increasingly widespread. Monochloramine is a leading alternative disinfectant that offers advantages for municipal water. This tech brief details the removal of monochloramine using activated carbon.

46. Industry-Specific Applications For UV Technology 6/17/2024

    In Microelectronics, Aquafine UV systems provide a synergistic approach towards the reduction of trace organics and microbial contamination for ultrapure water.

47. Water Treatment In Boilers And Cooling Towers 10/29/2021

     Most people recognize problems associated with corrosion. Effects from scale deposits, however, are equally important. For example, as little as 1/8" of scale can reduce the efficiency of a boiler by 18% or a cooling tower heat exchanger by 40%!

48. Innovative Solutions To Drinking Water Decontamination In Small And Medium Treatment Plants 9/21/2017

    Air stripping technology effectively removes VOCs, THMs, and CO2 for improved adherence to water quality regulations.

49. Bottled Water Industry: Liquid Analytical Solutions 11/10/2013

    Americans consume more than 9.1 billion gallons of bottled water annually - an average of twenty nine gallons per person every year. 

50. Water Determination In Liquefied Petroleum Gas Using GC BID And Ionic Liquid Column Watercol™ 6/28/2018

    Water in petrochemical feedstocks can cause problems for processors. Freezing of pipe lines and valves and poisoning of expensive catalysts are just a few examples.
