5100 Current Capabilities • H2O, CH4, CO2, H2S & O2 are the gas analytes that we can measure now. • Our laser platform will enable adding other lasers with minimum or no changes to the set up in the future. • Most measurements are for monitoring trace levels of the gas analytes in various backgrounds. • O2- we can do 1000 ppm LDL. • H20- Typical H2O levels in hydrocarbons 0-10 ppm subject to application. • H2S- we can do low level percentages ( > 1000 ppm)...
5100 - Future Capabilities • Measurement of CO, NH3, HCL • O2 – 200 ppm LDL. We will be able to target all the paramagnetic applications with laser. • Natural gas – 0-10 ppm moisture with an LDL of 1 ppm or better.
Current Target Applications • Petrochemical - Moisture, CO2,CH4 • Refinery- H2O, H2S • Natural Gas Processing-H2O, CO2, H2S, O2,CH4 • LNG Processing-H2O • Chemical-H2O, CO2, CH4 • Combustion Monitoring-O2, CO2

Key Feature of 5100Built-In Performance Verification • •
• •
•
External calibration is time consuming especially for polar species like water with long equilibration times. Model 5100 uses sealed reference cells (containing the analyte of interest in a buffer gas that does not absorb in the spectral range of interest) for quick analyzer verification. The reference cell value is accurate; we use engineering calculations to determine the actual concentration value. Since the value of the analyte concentration in the reference cell is known, the analyzer response is compared to it and the analyzer performance is verified every two seconds. Each gas analyte will have its own reference cell. We sometimes have the ability to mix two gas analytes in one reference cell.
Key Feature of 5100Laser Line Lock •
• •
Laser wavelength can drift due to slight changes in the ambient temperature. Even a very small wavelength error can result in much larger signal error in the derivative mode. The sealed reference cell contains a high concentration of the target analyte in a host gas, which does no absorb in the spectral range of interest. Part of the laser beam is passed through the reference cell. The spectra of the analyte sample in the reference cell are monitored and any shift in the observed peak is used as a feedback signal for the temperature control of the tunable laser diode
Key Feature of 5100Use of Fiber Optics • Use of fiber optics – Allows the isolation of the laser for better thermal control. – Allows for easier alignment of the optical system. – Simplifies the addition of internal reference cells. – Enables future options of remote cell assemblies.
5100 Calibration •
5100 analyzer does not require frequent calibration. – The tunable methodology enables zero baseline normalization every scan. – Built-in reference cell enables laser line lock and verification.
•
Standard gas bottles can be connected to the analyzer for a single point span check like we do with other gas analyzers. – Customers should have the ability to independently to verify the analyzer calibration.
• • • •
The span factor can be automatically adjusted after the calibration check. The span factor can also be manually adjusted. Calibration is background gas dependent. For example, use moisture in methane in the case of natural gas applications and not standard moisture gas bottles. We use NIST traceable gas standards for calibration.
