  • Ammonia (NH3) Slip Measurement with Continuous

    2020-4-133. Direct Measurement with Tunable Diode Laser. There’s a relatively newer method for measuring NH3 that has addressed some of the major issues with other NH 3 approaches. TDL uses a near-IR tunable diode laser absorption spectrometer to measure NH 3 in a process gas.. This is an in-situ measuring device meaning it measures directly in the stack or duct.

  • Measurement of NH3 Concentrations in Stack Flue Gas Using

    The ammonia (NH3) gas is injected to remove the NOx and thus reduce the NOx concentration in the stack flue gas. With conventional NH3 analyzers that perform measurements indirectly, NH3 concentrations are obtained through a sampling system. Therefore, there are problems with the maintenance and running costs of the sampling system, and time delays in measurement.

  • Measurement of NO, NO2, NH3, and O2 at the SCR outlet SICK

    The NO X concentration is typically measured at the outlet of the SCR to calculate the denitrification efficiency. Ammonia is measured to ensure that NH3 slip is low. The GM32 in-situ gas analyzer measures NO and NO 2 (NO X) concentrations in the exhaust duct – directly, quickly, and without gas sampling and transport.The GM700 TDLS in-situ gas analyzer continuously monitors low NH 3

  • Reducing NH3 Slip in Selective Catalytic Reduction (SCR

    This excess NH3 is known as Ammonia Slip. There are two major ways to monitor NH 3 Slip – Differential Chemiluminescence of sample with NH 3 conversion, or Tunable Diode Laser (TDL) which provides a direct NH 3 measurement. Each method has its own

  • Thermal Atomic Layer Etching of Titanium Nitride Using

    2017-11-15measurements. The TiN film on the silicon wafers was cleaved to produce samples that were 1.25 cm by 1.25 cm in size and used in the ALE experiments. For the selectivity experiments, the Al 2 O 3, HfO 2, ZrO 2, SiO 2, and Si 3 N 4 thin films on silicon wafers were placed together with the TiN sample in the reactor. The Al 2 O 3, HfO 2, and ZrO 2 films Figure 1.

    Freshwater Marine water Pond Water testing Care. Makes it easy to monitor the ammonium/ammonia level in fresh and marine water. Ammonium and ammonia mainly arise from fish waste. They are converted into each other depending on the pH value. While ammonium is mostly harmless, ammonia is toxic to fish. The sera NH
