PRODUCT ADVANTAGES I ~ I

_ What are the advantages of the Laser Detectors compared to Electrochemical or Catalytic Detectors?

Zeto Poisoning, No Ageing and No Cross-sensitivity:

Eh~ctrochemical detectors are always in direct contact with the gas. They , are prone to ageing as the measurement principle is based on a chemical

reaction depleting the sensor substance. This leads to short life times.

This life time decreases when the gas to be measured is present

frequently. The response is rarely specific to a single gas, which may lead

to costly false alarms. Issues with zero drift for multiple reasons are

frequent. Therefore, calibration is necessary in short intervals, which in

turn increases the cost-of-ownership for initially low-cost instruments.

The sensors are also sensitive to pressure and humidity changes. As the

laser gas sensor is an optical detector without direct contact to the gas, it

is not at all subject to pOisoning or degradation. Humidity and pressure

changes around normal atmospheric conditions have no influence.

Calibrations are enduring and recovery from high concentrations is

instantaneous.

Continuous Sensor Status Monitoring for Functional Safety:

The European norm IEC 61508 is regarded as "good practice" for

security sensors. It requires functional safety from any device and

needs redundancy and constant monitoring of the sensor status. With

an optical sensor, this is achieved by monitoring the light source

intensity (which is a basic feature of the laser gas detector

measurement principle). However, electrochemical gas sensors or

pellistors cannot comply with this norm as any testing degrades the

sensor performance and due to this operator of security sensitive

installations (chemical plants, refineries etc.) will have to replace

electrochemical sensors in the future.

High Dynamic Range:

Most detection technologies can either measure only low

concentrations (e.g. electrochemical detectors below 100 ppm) or

high concentrations (catalytic sensors in the % range) . The high

dynamic range of the laser gas detector makes it very versatile for

many applications, without the need to use 2 or 3 different detection

technologies in the same instrument to cover the range of interest.

Dalian Actech is demonstrating laser gas sensors to US oil companies.

What are the advantages of the Laser Detectors as compared to Solid State Sensors (MOS)?

No cross-sensitivity, no influence from environmental parameters:

Solid state sensors are sensitive to humidity and generally have poor

selectivity for toxic gases. Also, variations in the oxygen content lead to

unreliable readings. Exposure to high gas concentrations can lead to

irreversible changes to the O-gas reading, as well as to the sensitivity. On

the contrary, cross-sensitivity to other gases, humidity or oxygen is

virtually zero for the laser detector if the bands from the absorption fine

structure are carefully chosen. There is no direct contact to the gas to be

measured.

Low power consumption:

A solid state sensor needs to be continuously at high temperature to

be operational, which leads to significant power consumption . In

applications where this is an issue, e.g. portable instruments, the laser

detector could have the advantage of lower power consumption .

PRODUCT ADVANTAGES

_ What are the advantages of the Laser Detectors as compared to NDIR systems?

Both NDIR and the laser detector monitor the absorption of infrared light by the target gas - however, NDIR only achieves rather weak resolution. NDIR

detectors select the appropriate wavelength by filtering the light of a thermal emitter through an interference filter. This,filter has a spectral resolution

which is roughly a factor 1'000 weaker compared to the sharp laser measurement ifTDLS. While overlapping gas absorption bands can pose a serious

problem to NDIR detectors - particularly with ever-present water absorption bands, the high resolution approach of the laser detectors makes this a

non-issue, resulting in Zero Cross-Sensitivity.

Better long-Term Stability with Single-Channel Systems:

NDIR detectors need a second measurement channel as reference in

order to monitor the light intensity of the bulb that changes

intensity over time due to ageing. As the reference channel has a

separate detector and a separate narrow band interference filter,

difference in these devices compared with the measurement

channel and different ageing can lead to drift. Therefore calibration

needs to be relatively frequent. The laser detector uses a specia l

measurement technique connected to proprietary electronics, which

extracts the requ ired intensity information from the detector signal.

Therefore, there is no need for a reference channel or frequent

calibration routines.

lower Power Consumption : The thermal light bulb of a NDIR

detector uses electrical power to generate a broad spectrum of

intensit ies -like a light bulb in a ceiling lamp. The optical filter is

tuned to the gas absorption wavelength and therefore uses only a

tiny fraction of the emitted light, leaving the main portion of the

used electrical power wasted . In contrast to this, the laser diode of

the laser detector emits 100% of its light at exactly the wavelength

of interest, wasting only a minimal amount due to the conversion

efficiency of the laser. Therefore, the laser detector will have lower

power consumption in most applications.

_ What are the advantages of the Laser Detectors as compared to FTIR instruments?

FTIR analytical instruments can be used for multiple gas measurements in laboratory and some process applications. However, accurate and fast devices can

be expected to be at 10 or 20 times the price point of a laser detector. Standard instruments have susceptible optics (contamination) and measurements in

the lower ppm range are difficult. Furthermore they are sensitivity to vibrations and shock and often need expert operators. Bulkiness and relatively high

power consumption are not in favor of easy OEM integration, particularly for mechanical in-situ, gas-extractive set-ups.

Dalian Actech (up left) is selected as one leading innovator by US Environmental Defense Fund (EDF) that advance in the Methane

Detectors Challenge, a collaboration with seven oil and natural gas companies aimed at identifying next -generation technologies

that will help better monitor methane emissions from oil and natural gas operations, with the intent to ultimately promote

meaningful reductions of these gases.
