Flame Ionization Detector
-
A flame ionization detector converts a hydrocarbon gas concentration into an electrical signal. The flame is hydrogen fueled and burns in hydrocarbon free combustion air. Either side of the flame are two electrodes between which an electric field is generated by means of a polarization voltage. The sample is pre-mixed with the fuel gas and heated in the flame to a temperature at which the hydrocarbon molecules ‘crack’ and CH fragments appear. These CH fragments are oxidated by the oxygen in the combustion air resulting in the formation of CHO+ ions. The ion current then passes to the electrodes and the resulting current measured is proportional to the quantity of C atoms derived from organic compounds.The Thermo-FID features two separate microprocessor controlled pressure compensations to avoid any influence from environmental or sample conditions. In addition, the complete Thermo-FID range of analyzers are equipped with a flame trap that is used as a heated sample inlet filter. The measurement chamber and all material in contact with the sample gas are heated between 120°C and 200°C to avoid condensation.

Non-Multiplexed High Speed Continuous Function Card Overview
-
This type of system can be designed with benefits of both the multiplexed amplifier-per-channel and transient recorder systems. Benefits of the non-multiplexed amplifer-per-channel system include: High Sampling Rates: With an ADC per channel, the sampling rate is not encumbered with considerations such as multiplexing and post-amplifier settling time.Superior Filtering: With an ADC per channel, digital filtering can be used to augment analog filtering to achieve better anti-aliasing performance with much lower effective sampling rates.Superior Phase Matching: Digital filtering provides much steeper, more predictable rolloff rates and phase characteristics than analog filtering with greater stability with time and temperature changes at lower cost.

Mid-Range Gas Filter Correlation Carbon Monoxide Analyzer
Model T300M
-
The Model T300M CO analyzer measures low to mid ranges of carbon monoxide by comparing infrared energy absorbed by a sample to that absorbed by a reference gas according to the Beer-Lambert law. Using a Gas Filter Correlation Wheel, a high-energy IR light source is alternately passed through a CO filled chamber and a chamber with no CO present. The light path then travels through the sample cell, which has a folded path of 2.56 meters.The energy loss through the sample cell is compared with the span reference signal provided by the filter wheel to produce a signal proportional to concentration, with little effect from interfering gases within the sample. This design produces excellent zero and span stability and high signal to noise ratio, allowing excellent performance from low to high range.All T Series instruments offer an advanced color display, capacitive touch screen, intuitive user interface, flexible I/O, and built-in data acquisition capability. All instrument set up, control and access to stored data and diagnostic information is available through the front panel, or via RS232, Ethernet, or USB com ports, either locally or by remote connection.The Model T300M comes with NumaView™ Software. NumaView™ Remote PC Software allows for a remote connection with virtual interface and data downloading capability to analyzers operating NumaView™ Software.
