  • Monitoring of Hydrogen Sulfide in Industrial Processes

    Hydrogen sulfide, H2S, is a very poisonous, corrosive, and flammable gas. As such, it needs to be carefully monitored and controlled in industrial processes where it is generated or used. At relatively low concentrations, it has an odour of rotten eggs which effectively works as a warning, but at higher concentrations where it becomes acutely toxic and even lethal, it can no longer be smelled ...

  • Changing the Rules with Mass Detection

    How simplified detectors can provide mass data for every analytical run and speed up method development With access to multiple mass spectrometry systems of varying degrees of sophistication, Davy Guillarme (University of Geneva, Switzerland) wasn’t actively looking for new mass detection solutions. Nevertheless, the Waters ACQUITY QDa mass detector caught his eye. Why? Because it opens a ...

  • Ultra-Pure Proof with Mass Detection

    Before joining the newly formed Reach Separations in February 2012, I spent five years at AstraZeneca in analysis and purification (latterly as group lead in reversed phase and chiral purification). This experience gives me a good perspective of both the needs of “big pharma” and, more recently, the needs of a specialist separation solution provider. My ...

  • How to prepare for a chemical attack

    It is a shocking and sad reality that chemical attacks are happening in the world today. The threats continue to rise as global tensions become greater. It can only be a good thing to be prepared if one was to occur in your area. The first step in preparation is to understand more about what chemical attacks are. What are chemical attacks? Chemical attacks involve using toxic ...

  • Chlorine Dioxide gas detection: A comprehensive guide

    Introduction Some years agoago, the bleaching process in the paper industry was changed from using Chlorine (Cl2) as bleaching agent to Chlorine dioxide (ClO2). This was a challenge forThis posed a major challenge to industrial hygienists, as there were no sensors or detectors available that were specific to Chlorine dioxide: There was no sensor technology for gas detectors available that ...

  • Chemical disinfection of Legionella in hot water systems biofilm: a pilot-scale 1 study

    Legionella bacteria encounter optimum growing conditions in hot water systems and cooling towers. A pilot-scale 1 unit was built in order to study the biofilm disinfection. It consisted of two identical loops, one used as a control and the other as a ‘Test Loop’. A combination of a bio-detergent and a biocide (hydrogen peroxide + peracetic acid) was applied in the Test Loop three times under the ...

  • Chemical Industry: Sale of by-Product HCl Covers Cost of Emission Control System Problem Case Study

    Some of the specialty chemical processes at a major chemical manufacturer’s plant result in considerable HCl loading in the off-gas. The HCl must be removed before the off-gas can be discharged to the atmosphere. Production of saleable by-product HCl solution was an important goal when looking for a high-efficiency HCl removal system. The company wanted to achieve a very low level of ...

  • Developing Technologies to Detect Hydrogen Sulfide (H2S) Gas

    Abstract Hydrogen sulfi de (H2S) gas can cause nausea, headaches, unconsciousness, and death. Industries struggle to detect this deadly substance before it harms workers or communities. Safety system manufacturers have developed detectors that sense the H2S quickly and accurately. This paper illustrates, in general terms, considerations in effective placement of H2S detectors: ...

  • Fixed Versus Portable Gas Detection – Which Is Better?

    Did you know that workers are needlessly injured every year as a result of leaking toxic or combustible substances? Such incidents are known to involve a wide range of hazardous gases (including ammonia, carbon monoxide, chlorine, hydrogen sulfide, hydrocarbon vapors and so on). The sad reality is that most of these accidents are avoidable if only the workplace is adequately monitored. This leads ...

  • Implementation of an automatic and miniature on-line multi-parameter water quality monitoring system and experimental determination of chemical oxygen demand and ammonia-nitrogen

    An automatic, miniature and multi-parameter on-line water quality monitoring system based on a micro-spectrometer is designed and implemented. The system is integrated with the flow-batch analysis and spectrophotometric detection method. The effectiveness of the system is tested by measuring chemical oxygen demand (COD) and ammonia-nitrogen in water. The results show that the modified system ...

  • Chemical Industry: Ammonia Emergency Plan Calls on Packed Tower to Scrub Released Chemicals Case Study

    A few years ago Union Camp turned a corner. Management decided that advance planning would take the place of reacting after the fact to an emergency or regulatory agency demands. At Union Camp’s Dover, OH. facility, byproducts of the paper industry are converted into usable specialty chemicals for cosmetics, adhesives and other industries. Crystallization is a process used intensively with ...

  • Biomonitoring can measure what chemical monitoring cannot

    Algae and Daphnia (waterfleas) forewarn drinking water sector Biomonitors, instruments which measure the biological effects of different substances on organisms, detect substances which cannot be detected using chemicals anaylsis methods. This is also valid for combinations of substances which are present in the water in large concentrations. A well-functioning monitor is necessary since our ...

  • Studies on natural radioactivity of some Egyptian organic and chemical fertilisers

    Radiometry techniques were applied to evaluate the activity and concentration values of 238U, 232Th and 40K in four types of Egyptian made fertilisers. Also, radon and thoron concentration values were estimated for the same samples. The Hyper-Pure Germanium Detection System (HPGeDS) installed at the hot laboratories of Inchas, Cairo, and the Solid State Nuclear Track Detection System (SSNTDS) ...
