  • Moisture

    COSA Xentaur

    Moisture refers to the presence of a liquid, especially water, often in trace amounts. Small amounts of water may be found, for example, in the air (humidity), in foods, and in various commercial products. Control of moisture in products can be a vital part of the process of the product. There is a substantial amount of moisture in what seems to be dry matter. Ranging in products from grain to washing powders, moisture can play an important role in the final quality of the product. There are two main aspects of concern in moisture control in products: allowing too much moisture or too little of it. For example, water moisture in steel furnaces play a major role as this will have an great effect on the quality of the steel. Moisture also triggers corrosion in metal pipes which can create high costs.

  • Micro Coulometry

    COSA Xentaur

    Coulometry is the name given to a group of techniques in analytical chemistry that determine the amount of matter transformed during an electrolysis reaction by measuring the amount of electricity (in coulombs) consumed or produced. Coulometric titrations use a constant current system to accurately quantify the concentration of a species. In this experiment, the applied current is equivalent to a titrant. Current is applied to the unknown solution until all of the unknown species is either oxidized or reduced to a new state, at which point the potential of the working electrode shifts dramatically. This potential shift indicates the endpoint. The magnitude of the current (in amperes) and the duration of the current (seconds) can be used to determine the moles of the unknown species in solution. When the volume of the solution is known, then the molarity of the unknown species can be determined.

  • Ion Speciation

    COSA Xentaur

    Ion Speciation refers to the changing concentration of varying forms of an ion as the pH of the solution changes.

  • Purity Pro

    SF6 - COSA Xentaur

    Utilizing the SF6 Purity Pro''s small size and light weight it is very easy to carry and transport. The SF6 Purity Pro also requires zero warm-up time increasing your efficiency and costs in the field. Truly a great asset for making your measurements when time and accuracy are of great importance.

  • Relative Humidity

    COSA Xentaur

    The amount of water vapor in the air at any given time is usually less than that required to saturate the air. The relative humidity is the percent of saturation humidity, generally calculated in relation to saturated vapor density. Relative humidity is the ratio of the current absolute humidity to the highest possible absolute humidity (which depends on the current air temperature). A reading of 100 percent relative humidity means that the air is totally saturated with water vapor and cannot hold any more, creating the possibility of rain. This doesn''t mean that the relative humidity must be 100 percent in order for it to rain -- it must be 100 percent where the clouds are forming, but the relative humidity near the ground could be much less.

  • Nuclear Magnetic Resonance

    COSA Xentaur

    Nuclear magnetic resonance (NMR, is a phenomenon which occurs when the nuclei of certain atoms are immersed in a static magnetic field and exposed to a second oscillating magnetic field. This energy is at a specific resonance frequency which depends on the strength of the magnetic field and the magnetic properties of the isotope of the atoms; in practical applications, the frequency is similar to VHF and UHF television broadcasts (601000 MHz). NMR allows the observation of specific quantum mechanical magnetic properties of the atomic nucleus.

  • Stack Oxygen Analyzer

    COSA Xentaur

    Oxygen analyzers provide valuable measurements in combustion control, process quality, safety and environmental applications. These are used in a variety of measurement scenarios including, but not limited to, boiler trimming in power plants, furnace optimization in refinery and petrochemical applications, process safety in vent headers, and product quality in ethylene production.

  • Dew Point

    COSA Xentaur

    Dew Point Temperature is a measure of humidity. If air is cooled eventually enough energy will be removed for water vapor to begin to condense. The temperature where condensation begins is the dew point temperature. If the air is gradually cooled while maintaining the moisture content constant, the relative humidity will rise until it reaches 100%. This temperature, at which the moisture content in the air will saturate the air, is called the dew point. If the air is cooled further, some of the moisture will condense.

  • Gas Chromatography

    COSA Xentaur

    Gas chromatography (GC), is a common type of chromatography used in analytical chemistry for separating and analyzing compounds that can be vaporized without decomposition. Typical uses of GC include testing the purity of a particular substance, or separating the different components of a mixture (the relative amounts of such components can also be determined). In some situations, GC may help in identifying a compound. In preparative chromatography, GC can be used to prepare pure compounds from a mixture.

  • Emissions Analysis

    COSA Xentaur

    The speciation of components in an exhaust gas stream typically coming from an internal combustion engine, boiler or turbine the values of which are used in combustion efficiency control or environmental monitoring.

  • Wobbe Index Calorimeter / BTU

    COSA Xentaur

    The Wobbe Index (WI) or Wobbe number[1] is an indicator of the interchangeability of fuel gases such as natural gas, liquefied petroleum gas (LPG), and town gas and is frequently defined in the specifications of gas supply and transport utilities. The Wobbe Index is used to compare the combustion energy output of different composition fuel gases in an appliance (fire, cooker etc.). If two fuels have identical Wobbe Indices then for given pressure and valve settings the energy output will also be identical. Typically variations of up to 5% are allowed as these would not be noticeable to the consumer.
