  • Overview of Rotating Disc Electrode (RDE) Optical Emission Spectroscopy for In-Service Oil Analysis

    Introduction The basis of modern oil analysis is the use of optical emission spectroscopy (OES) to measure the ppm (parts per million) levels of wear metals, contaminants and additives in oil samples. Whatever else an oil lab may measure, a multi-elemental analysis is the core of in-service oil analysis. This paper gives an overview of Rotating Disc Electrode Elemental Spectroscopy and its ...

  • Spectroscopic tools for remote sensing of greenhouse gases CH 4, CF 4 and SF 6

    Abstract Highly symmetrical molecules such as CH 4, CF 4 or SF 6 are known to be atmospheric pollutants and greenhouse gases. High-resolution spectroscopy in the infrared is particularly suitable for the monitoring of gas concentration and radiative transfers in the earth's atmosphere. This technique requires extensive theoretical studies for the modeling of the spectra of such molecules ...

  • Detection of early PFA seals (perfluoroalk-oxyethylene) degradation exposed to process gases inside a reactor chamber

    Problem Statement Replacement of PFA seals inside the reactor chamber is performed according scheduled maintenance and life expectancy of the seals. Early degradation of seals goes completely undetected until there is a complete failure of the seal, letting atmospheric contaminants inside the reactor and forcing an unscheduled reactor downtime. IRGAS ...

  • Monitoring the performance of moisture purifiers for process gases

    Problem Statement Moisture purifiers are a big aid in keeping moisture levels under control inside a process chamber. They are provided by manufacturers with certain life expectancies, which vary depending on the moisture content of the gas being purified. As a result, it is difficult to determine which gases have a high moisture content and which moisture purifier is becoming ...

  • Continuous monitoring of moisture present inside a process chamber

    Problem Statement Moisture inside a process chamber is a big silent killer during wafer production. When production yield goes down, it is hard to pinpoint the source of the problem. Most of the time wafers need to be sent to labs for analysis, while production is stopped. If the problem is related to a high level of moisture inside the reactor, there are several factors that can cause ...

  • Detection and measurement of toxic gases from destructive testing of batteries

    Problem Statement New formulations of organic-compound-based batteries for vehicle use must be tested for release of potentially harmful and toxic gases if crushed in accidents. Potential gases include hydrocarbons, fluorocarbons, and hydrogen fluoride, released within seconds of an incident. Actual time-resolved and quantitative data are required from destructive testing to ascertain ...

  • Water and environmental analysis according to US EPA regulations using the lambda 25/35/45 UV/Vis spectrophotometers

    UV/Vis spectroscopy is an important analytical technique used for the determination of many water constituents. Environmental regulations in many countries prescribe the use of UV/Vis spectroscopy. Depending on the method, UV/Vis determinations of metal and organic nonmetal analytes in water have a minimum detectability in the ppb-ppm range. The Lambda UV/Vis Spectrophotometers ...

  • Atmospheric particulate matter in the city of Sao Carlos/SP, Brazil

    This paper presents experimental data and source apportionment simulations on particulate matter (PM10 and PM2.5) in the atmosphere of Sao Carlos/SP, Brazil. Both a Hi-vol sampler equipped with glass fibre filters and a Dichotomous sampler with nucleopore filters were used. The collected material was analysed for total carbon, using a thermometric method, and for ...

  • Beer`s law

    The Beer-Lambert relationship (or Beer's law) states that the concentration C is directly proportional to the absorbance A. Generally, this relationship is more often applied by comparing the height of a maximum absorption peak of a reference gas to the height of the corresponding peak in a sample spectrum. However, this technique suffers if the baseline is not accurately known, and it fails ...

  • Smart Infrastructure is Key for QA/QC

    Paperless, or more accurately integrated, labs enjoy streamlined operations with better data, while minimizing costs, validation and maintenance. Laboratories responsible for QA/QC are a sum of many parts, but no part is more important than data. Data is THE product, and the integrity of that data is more than critical to today’s pharmaceutical laboratories. So what happens when processes ...
