  • 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 ...

  • Measurement of moisture in HBr

    Introduction Moisture in corrosive gases will accelerate the rate of metal corrosion in gas supply systems which, in turn, can lead to their premature failure. For this reason, it is important to monitor moisture levels in these gases. FTIR is an effective way to monitor for moisture in these corrosive gases. In order to determine low levels of moisture in corrosive gases, it is ...

  • Detection of moisture in ammonia gas

    Problem Statement As technologies advance, so does the request for ultra high purity ammonia. Ultra high purity (UHP) ammonia is used in the semiconductor industries, production of flat panel displays, and a number of other applications. Due to this rising interest in UHP ammonia, manufacturers are having to battle ammonia’s most prominent and damaging impurity--moisture. For ...

  • Sampling moisture in the soil profile

    Patterns of water replenishment and use give rise to large spatial variations in soil moisture over the depth of the soil profile. Accurate measurements of profile water content are therefore the basis of any water budget study. When monitored accurately, profile measurements show the rates of water use, amounts of deep percolation, and amounts of water stored for plant use.Experimental ...

  • Moisture in Oils: The Three-Headed Beast

    Abstract Moisture contamination in in-service lube oils is perhaps one of the most destructive forms of engine corrosion second only to particle contamination.  Water contamination in oil can be categorized into three forms of water; Free, emulsified, and dissolved.  All forms of water have direct consequences to the oil and gears of the engine, but indirect consequences as ...

  • Moisture Audits & Analyser Performance Assessments at Woodside, Karratha - Case Study

    Woodside had been experiencing intermittent blockages in 4/5 S1406 LNG trains since September 2008 and had been unable to pinpoint the source of the problems. Repeated hydrate formations were leading to reduced productivity and the existing process monitoring instrumentation had failed to confirm moisture breakthrough on the beds. The site's existing Panametrics portable moisture analysers had ...

  • Determining levels of moisture permeation through Kalrez and Chemraz o-ring material

    Problem Statement As the manufacturers of corrosive resistant gas cells we are often called upon to design a system for the detection of moisture in various gases. Most of our requests are to detect moisture in the low ppb levels. This can be a rather difficult task to accomplish when the surrounding environment has high levels of moisture (humidity). There are several steps that we ...

  • Thermal Patters Due to Moisture Accumulation within Exterior Walls

    In cold climates, air leakage is accompanied by moisture transport. When migrating through dew point temperatures, a considerable amount of moisture accumulation may occur depending on variables such as the duration of sub-zero exterior temperatures, building pressurization, wind effects and the level of interior relative humidity. Moisture accumulation may result in premature deterioration of ...

  • Improved Water Supply Forecasts Using Soil Moisture Data

    HydraProbe used to improve water supply forecast from 3 SNOTEL sites in Idaho over traditional antecedent conditions using the principle component forecast model Much of the water in the Western United States used for irrigation, municipal supplies and hydro-electric production originates as winter snow pack at higher elevations. Since the early 1900s, the correlation between stream flow and the ...

  • The Role of Soil Moisture on our Climate, Weather and Global Warming

    Global warming is a topic that has received much attention in the media, especially during the hot days of summer. The process by which carbon dioxide (CO 2) in the atmosphere prevents the escape of thermal energy into outer space is known as the green house effect. The higher the carbon dioxide levels in the atmosphere the less thermal energy that can escape thus an increasing global ...

  • An analysis of extinction coefficients of particles and water moisture in the stack after flue gas desulfurization at a coal-fired power plant

    Two important factors that affect in-stack opacity—light extinction by emitted particles and that by water moisture after a flue gas desulfurization (FGD) unit—are investigated. The mass light extinction coefficients for particles and water moisture, kp and kw, respectively, were determined using the Lambert-Beer law of opacity with a nonlinear least-squares regression method. The ...

  • Noise Monitors and Meters

    Sound level meters Description and ApplicationsThe sound level meter is a lightweight instrument for the measurement of sound pressure level (SPL) in decibels. All ANSI-approved meters meet minimum requirements that include an A-weighted network, a slow-response meter characteristic, and a fully graduated scale with measurements ranging from 80 to 130 dBA. The Type II meter is most frequently ...

  • HydraProbe Field Portable Used to Validate the Soil Moisture Active Passive Satellite Data in Manitoba

    The calibration and validation of remotely sensed soil moisture products relies upon an accurate source of ground truth data. The primary method of providing this ground truth is to conduct intensive field campaigns with manual surface soil moisture sampling measurements, which utilize gravimetric sampling, soil moisture probes, or both, to estimate the volumetric soil water content. Soil ...
