  • An urgent and ongoing need to test steel punches for the pharma industry

    Nottingham-based I Holland supplies steel dies and punches to the pharmaceutical industry to manufacture tablets. In July 2017 they had an urgent need to identify and sort a large quantity of punches. Unable to do so accurately themselves, they turned to Hitachi High-Tech for a Vulcan laser analyser. I Holland was so impressed with the Vulcan that they purchased their own which is now in use ...

  • Trust your supplier, but also check

    In the wake of mis-certification scandals around the world, firms are tightening their quality assurance (QA) processes using materials analysers. Industry has been shaken recently by news of companies providing false certification in a range of fields, from emissions testing through to metal grading. Cases where suppliers have delivered mislabelled products only serve to highlight the importance ...

  • Real-time O2 monitoring in VCM plants using the In-situ laser gas analyzer – Case Study

    Vinyl Chloride Monomer (VCM) Vinyl Chloride Monomer is a colorless, flammable gas. It is of very great importance as feedstock in the production of polyvinyl chloride (PVC), one of the world´s most versatile thermoplastics. Originally, acetylene has been used as feedstock for VCM production but was replaced stepwise by the inexpensive ethylene. Complete changeover to almost ...

  • Insitu analysis of ammonia slip and water vapor using a tunable diode laser for SCR/SNCR optimization and boiler tube surveillance in power plants

    ABSTRACT Environmental Regulations driven by the 1990 Clean Air Act require Power Plants to reduce NOx emissions. SCR's and SNCR's reduce NOx emission by injecting ammonia into the combustion flue gas. which ideally reacts with the NOx to form H?0 and Nj. The efficiency of the SCR SNCR is determined by monitoring the outlet for excess NH3. referred to as NH3 slip. The flue gas sample ...

  • What is a Spectrometer?

    The characteristics of a white LED light differs greatly, when compared to a yellow CFL. Without any special tools, one can see that the LED emits a clear white color, while the CFL generates yellow light. Going one step further, using a spectrometer, one will be able to “dissect” the light sources and see that they are composed of other colors in the visible light spectrum, such as ...

  • Argon Gas, 3D Printing, and How to Stay Safe

    For the average person, Argon gas is not a topic of daily conversation, or, for that matter, any conversation, ever. It may be surprising to learn that argon is the third most common gas in the earth’s atmosphere, though most people know little about it. The word argon itself comes from a Greek word meaning ‘inactive’ because of its lack of chemical reactions. Argon is ...

  • Model 5100 Verification/Validation case study

    Background Many sensors used in gas analyzer systems come into direct contact with the process gas, and there is the potential for degradation over time especially with streams that contain contaminants like glycol, moderate to high levels of hydrogen sulfide etc. With sensor degradation, the analyzer response characteristics change resulting in inaccurate readings. In order to ...

  • Continuous measurement of Process oxygen for Claus sulfur recovery unit (sru) start-ups and shut-downs case study

    During start-up and shut-down, any time a sulfur recovery unit (SRU) transitions from ambient temperature through fuel gas warm up to the introduction of acid gas, measurement of 02 stoichiometry is critical. Historically, operators have manually taken samples using a portable electrochemical type Os analyzer. While giving more or less satisfactory results, the requirement for more stringent ...

  • Low level moisture measurement in Natural gas using a Lunable diode laser absorption spectroscopy (tdlas) based laser case study

    Introduction The measurement of water vapor in natural gas has long been of industrial importance, and has been addressed by a variety of analytical techniques over the years. Chief among these techniques has been the quartz crystal microbalance (QCM) based analyzers. The QCM technology is still the workhorse for production and pipeline applications, and the technique is considered by most ...

  • Measurement of a Doubly Substituted Methane Isotopologue, 13CH3D

    ABSTRACT: Methane is an important energy resource and significant long-lived greenhouse gas. Carbon and hydrogen isotope ratios have been used to better constrain the sources of methane but interpretations based on these two parameters alone can often be inconclusive. The precise measurement of a doubly substituted methane isotopologue, 13CH3D, is expected to add a critical new dimension to ...
