In situ through type laser absorption spectroscopy gas analyzer-Fornitore globale

A207 Rongchuang Power Document Creative Industry Base, No. 32, Courtyard 5, Guangshun North Street, Chaoyang District, Beijing

Four types meet different measurement requirements:

LAS 300 XD HF measurement of HF and moisture
LAS 300 XD HCL measurement of HCL and moisture
LAS 300 XD NH3 Measurement of NH3 and Moisture
LAS 300 XD O2 measurement of oxygen
LAS300 XD CO/O2 simultaneous measurement of carbon monoxide and oxygen

Product advantages:

High sensitivity (capable of measuring ppb and ppm concentrations)

Measurement is not affected by interference from other gas components

Larger dynamic measurement range

Absolute measurement: no drift, no calibration required, linear response

Real time measurement (response time of 1 second)

In situ installation of flue gas outside (optical technology)

Suitable for harsh on-site environments, sensors are not easily contaminated (corroded)

Eliminating errors in the sampling process of the extraction method
Lower maintenance volume and cost

Main applications:

Process analysis, combustion control, emission monitoring, chemical plants, fertilizer plants

Petrochemical industry, power plants, waste incineration plants, cement plants, glass plants

Pulp and paper mills, flue gas scrubbing equipment, biomass boilers

System Description:

Adjustable diode laser spectroscopy is an excellent measurement technique that can selectively and rapidly measure certain gas components including NH3, HCL, HF, CO, and can also measure oxygen under harsh environmental conditions. use

Solid state laser emission technology, which modulates the wavelength of the laser source to a specific range, is also known as the fingerprint spectrum of gas components.

TDLS is a non-contact measurement method, so there is no risk of contamination and corrosion of the emitting light source, and maintenance and operation costs are much lower compared to other methods. Thanks to its fast A/D conversion, Direct Absorption Spectroscopy (DAS) is more suitable for TDIS analyzers compared to Wavelength Modulation Spectroscopy (WMS).

Through DAS technology, the LAS 300 analyzer series can achieve the following functions:

Measure very low concentration range (several PPBs)
Measure very high gas concentrations - with a large dynamic range
Very high-precision measurement (absorption spectrum directly related to molecular structure, using reliable signal processing algorithms to measure single gas and multi-component gas)
Measurement has a very high linear correlation (spectral absorption is calculated according to Lambert Beer's law)

The LAS 300 XD analyzer uses TDL and DAS technologies to measure ammonia leakage during denitrification processes, and is applied for ammonia measurement in SCR, SNCR, or urea fertilizer plants. This device can be used for both HCL measurement in raw flue gas and low concentration HCL measurement in incineration processes And the measurement of CO and oxygen in process control.
